Anthropologists awarded major early-career development support Rachel Sauer Fri, 05/30/2025 - 15:44

91�� scholars William Taylor and Fernando Villanea have been named 2025 National Science Foundation CAREER award winners

Two 91�� anthropologists have been named 2025 Faculty Early Career Development (CAREER) award winners by the National Science Foundation (NSF) to support their research of animal domestication and genomic variation.

William Taylor, a 91�� assistant professor of anthropology and CU Museum of Natural History curator of archaeology, has been awarded a $419,696 grant for his research project “Understanding Animal Domestication and Human-Environmental Relationships.” Fernando Villanea, an assistant professor of anthropology, has been awarded a $579,010 grant to study “Archaic Hominin Genomic Variation in Modern Human Populations.”

William Taylor, a 91�� assistant professor of anthropology and CU Museum of Natural History curator of archaeology, has been awarded a $419,696 NSF CAREER grant for his research project “Understanding Animal Domestication and Human-Environmental Relationships.”

The NSF CAREER Program offers the foundation’s most prestigious awards in support of early-career faculty “who have the potential to serve as academic role models in research and education and to lead advances in the mission of their department or organization,” according to the NSF. “Activities pursued by early-career faculty should build a firm foundation for a lifetime of leadership in integrating education and research.”

“Funding from this grant means my research team’s salaries will be supported for the next five years, including hiring a new post-doctoral scholar, to explore the effects of Neanderthal and Denisovan ancestry in living people,” Villanea says. “A portion of the grant will also fund functional genetic experiments in collaboration with scientists at the CU Anschutz School of Medicine.”

Taylor notes that this award “is a tremendous honor and a huge step forward in our scientific investigation of the past. Ancient Mongolia was deeply intertwined with so many parts of the story of animal domestication, from dogs to horses, reindeer, and beyond. It’s exciting we will be able to start exploring that with our interdisciplinary team at CU over the years ahead.”

Doing community archaeology

Taylor’s research aims to understand animal domestication and human-environmental relationships on northeast Asian prehistory through archaeology.

His NSF CAREER project will investigate rare, well-preserved archaeological and biological assemblages recovered from archaeological field research in western Mongolia—including new finds from high mountain snow and ice features and excavation of stratified dry caves—spanning the last four millennia and beyond.

The research will be paired with a multifaceted program of museum education and outreach, building on Taylor’s past findings, providing infrastructure for the protection of cultural resources and the cultivation of international scientific cooperation while supporting early-career scientists and expanding public education in Mongolia and the United States.

The NSF CAREER support will aid Taylor and his Mongolian partners, including the Mongolian Academy of Sciences and National Museum of Mongolia, to analyze ancient animal remains, artifacts and ecofacts with cutting-edge techniques from archaeozoology, biomolecular sciences and paleoenvironmental data from the Mongolian Altai. The research team will seek to establish data-driven models for the introduction and dispersal of domestic livestock to northeast Asia; the timing and role of Mongolian cultures in the innovation of large animal transport, including the chariot, the saddle/stirrup and reindeer riding; and the relationship of key social developments to ancient environments in the eastern Steppe.

Fernando Villanea, an assistant professor of anthropology, has been awarded a $579,010 NSF CAREER grant to study “Archaic Hominin Genomic Variation in Modern Human Populations.”

“Leveraging partnerships and expertise from scientists and institutions at home and abroad, this award will produce key scientific research on animal domestication and the human story,” Taylor noted, adding that the CAREER award will help “to build important educational tools and capacity for a future generation of scientists and scholars, along with strong international partnerships and scientific cooperations between Mongolia and the United States.”

Archaic genetics, modern applications

Villanea’s NSF CAREER research begins with the concept that “living people carry archaic genetic material inherited from other hominins such as Neanderthals and Denisovans. This genetic inheritance can affect fitness and health, and its persistence and effects cannot be fully understood unless studies consider each group’s unique population history and the evolutionary processes that shaped them,” he explained.

The goal of Villanea’s study is to assess the presence and evaluate the impact of archaic hominin ancestry in groups with a complex population history by applying sophisticated computational genetic techniques to existing information. Villanea and his research colleagues aim to develop educational tools, provide training opportunities for students at different educational levels and build capacity in a new generation of scientists.

This research advances knowledge of archaic ancestry in groups with complex admixture. To separate the archaic ancestry contributions from those derived from modern groups, this study analyzes the genomes of individuals that predate well-documented historic processes as well as those from modern peoples. To improve admixture models, the study creates computational tools that benefit from artificial intelligence techniques. The study examines the relationship between archaic gene variants and phenotypic traits.

Villanea’s research will focus on the Neanderthal and Denisovan ancestry distribution in Indigenous American and descendant Latin American genomes, promoting understanding of the forces of evolution as they acted in Indigenous American and descendant Latin American genomes. A goal is that the knowledge gained will empower underrepresented students to access higher education in medical and STEM fields.

“Computational and statistical competency is a lower cost of entry to STEM and medical sciences than hands-on experience in laboratory techniques, and I believe that this trend is democratizing access to genomics research across all institutions,” Villanea noted. “The trend towards free access to scientific resources is exemplified by the public availability of modern and ancient genomes, and the acceptance of preprint services to remove paywalls to exciting new results and methodologies.

“For this reason, I advocate for the inclusion of computational competency in the curriculum for all students, and see an opportunity for online resources to provide an early form of access to evolutionary theory for pre-college level students that can both grow their interest in biology and improve their chances at academic development by equipping them with high-level theory they can be self-taught supplementing their school curriculum.”

Newly opened exhibit at the University of Colorado Museum celebrates ceramic artist’s donation and the legacy of her family and community

A new piece of Acoma Pueblo pottery begins, in a way, with all the pottery that came before it.

Artisans finely grind shards of old pottery and mix it into clay gathered from Acoma Pueblo land, hand-forming the light yet strong vessels for which they are renowned. There are no precise measurements, no written recipes, for the clay or slip or mineral paints that come together in Acoma Pueblo pottery; “you just know when it’s right,” says artist Dolores Lewis Garcia.

Noted Acoma Pueblo ceramics artist Carmel Lewis Haskaya, a proud 91�� alumnus, ensured that her love for her community and its traditions would unite with her love for 91�� by donating one of her pieces to the University of Colorado Museum.

Lewis Garcia learned the art from her mother, Lucy M. Lewis, the famed New Mexico ceramics artist known for reviving traditional pottery techniques whose work is displayed in the Smithsonian National Museum of the American Indian. Most of Lewis’ nine children learned by watching her and also became ceramic artists, including her youngest, Carmel Lewis Haskaya.

Lewis Haskaya was not only a respected ceramic artist, but a proud 91�� alumnus. Before her death in 2019, she ensured that her love for her community and its traditions would unite with her love for 91�� by donating one of her pieces to the University of Colorado Museum.

The vibrant cylindrical pot is a centerpiece of the new exhibit “A Family Tradition: Acoma pottery, CU and the Lewis family,” which opened with a reception and ribbon cutting Tuesday evening.

“We are delighted to highlight and honor the important artworks that this family has shared with us,” says Nancy J. Stevens, 91�� professor of anthropology and director of the Museum Institute. “It represents a pivotal point for connecting communities and growing meaningful collaborations into the future.”

The exhibit features pieces by Lucy Lewis and many of her children, including Forever Buff Carmel Lewis Haskaya.

“(Lewis Haskaya’s cylinder jar) is not just an object or a gift,” explains William Taylor, a 91�� assistant professor of anthropology and CU Museum curator of archaeology who partnered with the Lewis family to create the exhibit.

“For many folks, creating pottery is a way to impart something of yourself in a permanent and lasting way. Having this pottery at CU means that a part of Carmel and her family will always be here in 91��.”

Learn by watching

Lewis Haskaya belonged to an artistic lineage that can be traced in centuries. For hundreds of years, Acoma Pueblo artists have gone to certain spots on their land to collect the clay, white slip, wild spinach and oxides that are the raw materials for their pottery.

“Being an Acoma potter, there’s a lot of work that goes into it,” Lewis Garcia says.

“Everything is gathered from the land and hand-processed,” adds Claudia Mitchell, also a famed Acoma Pueblo artist and Lewis’ granddaughter. “It teaches you to take your time and be present; you’re putting yourself into the work.”

As a child, Lewis Haskaya learned these traditions and techniques watching her mother. When she came to 91�� through the American Indian Educational Opportunity Program and built a career with the Native American Rights Fund, she never forgot or outgrew her community, Mitchell says. Eventually, Lewis Haskaya returned to her community at Acoma, west of Albuquerque, New Mexico, and became an accomplished artist.

Lewis Haskaya was a student of history and art traditions from around the world and was known for creating cylinder vessels in the style of ones found at Chaco Canyon, Mesa Verde and other ancient sites, adding her own touch to traditional designs.

The cylindrical vessel made by noted Acoma Pueblo artist Carmel Lewis Haskaya, which she donated to the University of Colorado Museum before her death in 2019.

“She had the hardest time grinding mineral paints,” Lewis Garcia recalls with a laugh, adding that her sister eventually conquered the hurdle that many artisans using traditional techniques encounter.

Like her mother and siblings, and now her nieces and nephews, Lewis Haskaya walked Acoma land to specific spots for the gray and yellow clays, the minerals and the plants that are the foundation of traditional techniques. “To get the white slip, it’s not in an easy place,” Lewis Garcia says. “It’s underground and there’s a big boulder on it. You have to use it sparingly.”

Though it’s more common now to use kilns rather than dung fires, the process of thinning vessel walls, of burnishing with a stone, of applying the geometric patterns associated with Acoma Pueblo pottery hasn’t changed for centuries.

‘The ties that bind us together’

While pottery is revered as art, “in our traditional ways, it’s a utility, it’s an item that we use,” says Benny Shendo Jr., 91�� associate vice chancellor for Native American affairs and a member of the Jemez Pueblo Tribe. “And it plays a big role in our ceremonial life.”

Mitchell notes that traditional pottery helps not only those who make it, but those who use it to “ground ourselves to the place that we’re from; it’s that connection that we have to our land and to our people—not only just for personal use, but for community use. It gives us that tie to one another. We’re keeping those traditions alive not only through our dance and song but through our pottery.

“Those are the ties that bind us together, that make us a people. It’s important to keep those ties, to make sure that those things—the pottery making, the dancing, the singing—all of those are taught to our younger generations, because that helps them identify who they are and where they are. It helps give them a sense of place and sense of purpose.”

“It’s part of life,” says Diana Lim Garry (Anth'71), Lucy Lewis’ granddaughter who lives in 91�� and helped bring the exhibit to life, loaning pieces from her own collection. “Everywhere we go—you’re walking on a hike and you’re walking along the streambed, and you’re saying, ‘Would that make a good polishing stone?’ You go along, even (in) roadcuts there’s all these pretty colors of the minerals in the rocks: ‘Would that make good paint?’ It’s always on your mind that this is something that’s been done for a long time and will continue to be done thanks to my aunts and my cousins.”

Mitchell adds that a pottery vessel made in traditional ways allows the Acoma Pueblo people to say “I have my piece of the rock. That’s how we identify ourselves, by place and name, that’s our place in this world, and no matter where we go in this world, we can always go back to that one place, and that’s where we belong. For our people, that’s who we are, that’s where we’re from.”

"A Family Tradition: Acoma pottery, CU and the Lewis family” is open to the public during regular museum hours, which are 9 a.m. to 5 p.m. Tuesday through Friday and 10 a.m. to 4 p.m. Saturday and Sunday.

Pieces made by famed Acoma Pueblo artist Lucy M. Lewis are part of the new University of Colorado Museum exhibit "A Family Tradition: Acoma pottery, CU and the Lewis family."

Following in the footsteps of her grandmother, Lucy M. Lewis, Acoma Pueblo artist Claudia Mitchell made these pieces using traditional techniques and designs.

91�� researcher Carla Jones finds that what Indonesian women wear in court can convey messages of piety and shame, or just the appearance of them

No matter who you are and what clothes you have on, you have probably, at some point, thought about how what you wear affects how you are seen.

Fashion is an important mode of self-expression, but it can also be a significant component of social communication. 91�� anthropology Professor Carla Jones’ recently published research focusing on fashion within the Indonesian criminal justice system illustrates how appearance can be a public and personal feature of social and political communication.

91�� researcher Carla Jones, a professor of anthropology, noticed that when Indonesian women were accused of corruption, they faced intense scrutiny about their appearances, both before and during their trials.

Jones’ interest in Indonesia started when she visited the country in college, but her youth in Southeast Asia also played a part in her sustained interest in the culture there. As an anthropologist, she says, she is interested in diversity–in which Indonesian culture and social life is rich.

She also credits her interest in learning to speak Indonesian with her total immersion there. “Learning a new language can change your life,” she says. “Cultural anthropologists need to be able to ask questions and understand. You have to learn how to be an insider and an outsider at once.”

In the past two decades, public political culture in Indonesia has become increasingly focused on corruption. Although Indonesia is not unusually corrupt, many of the most visible corruption trials have captivated public attention through media focus on theft of public funds.

Jones noticed that when women were accused of corruption, they faced intense scrutiny about their appearances, both before and during their trials. Jones says she noticed that female defendants in corruption cases adjusted their clothing in ways that went far beyond the public norms for the majority-Muslim country.

Modesty was a particularly compelling visual strategy. Although modest styles are increasingly popular globally (think: trad-wife trends on TikTok), the styles that accused Indonesian women adopted for trials were especially visible when they appeared in court and were very different from their styles of dress prior to their trials, Jones says.

Many women, she says, would elect to wear facial coverings, called a niqab or cadar, when appearing before a judge. Wearing a niqab is not especially common in Indonesia. Jones argues in her paper that women choosing to express their religion so outwardly was also an effort to appear more pious and ashamed of their actions (or more innocent) to judges and to the public.

Niqab in court

So, does it work? According to Jones, yes, along with other factors. The women in these cases who wore a niqab to court tended to get shorter prison sentences than others did. “Their attorneys also did a really good job conveying that they are mothers, and their justification was to provide for their children,” she says.

However, that doesn’t mean these women on trial were received the same way all over the world. When Anniesa Hasibuan, an internationally famous modest-fashion designer who was charged with fraud, took the stand in West Java, the coverage expanded to all over the world, including the United States.

The international coverage of Hasibuan’s trial called additional attention to her choice to wear a niqab. Some Indonesians who were following her case closely viewed her choice to cover her face much as some Americans might: as an attempt to foreclose transparency about her appearance and therefore her finances. Many Indonesians viewed her appearance as a sign of dishonesty rather than piety.

In the archaeological record, size does matter

In the archaeological record, size does matter Rachel Sauer Mon, 04/14/2025 - 09:24

91�� archaeologist Scott Ortman and colleagues around the world explore relationships between housing size and inequality in PNAS Special Feature

If the archaeological record has been correctly interpreted, stone alignments in Tanzania’s Olduvai Gorge are remnants of shelters built 1.7 million years ago by Homo habilis, an extinct species representing one of the earliest branches of humanity’s family tree.

Archaeological evidence that is unambiguously housing dates to more than 20,000 years ago—a time when large swaths of North America, Europe and Asia were covered in ice and humans had only recently begun living in settlements.

Between that time and the dawn of industrialization, the archaeological record is rich not only with evidence of settled life represented by housing, but also with evidence of inequality.

91�� archaeologist Scott Ortman partnered with colleagues Amy Bogaard of the University of Oxford and Timothy Kohler of the University of Florida on a PNAS Special Feature focused on housing size in the archaeological record and inequality.

In a Special Feature published today in the Proceedings of the National Academy of Sciences (PNAS), scholars from around the world draw from a groundbreaking archaeological database that collects more than 55,000 housing floor area measurements from sites spanning the globe—data that support research demonstrating various correlations between housing size and inequality.

“Archaeologists have been interested in the study of inequality for a long time,” explains Scott Ortman, a 91�� associate professor of anthropology who partnered with colleagues Amy Bogaard of the University of Oxford and Timothy Kohler of Washington State University to bring together the PNAS Special Feature. (Special Features in PNAS are curated collections of articles that delve into important topics.)

“For a long time, studies have focused on the emergence of inequality in the past, and while some of the papers in the special feature address those issues, others also consider the dynamics of inequality in more general terms.”

Kohler notes that "we use this information to identify the fundamental drivers of economic inequality using a different way of thinking about the archaeological record—more thinking about it as a compendium of human experience. It’s a new approach to doing archaeology.”

Patterns of inequality

Ortman, Bogaard and Kohler also are co-principal investigators on the Global Dynamics of Inequality (GINI) Project funded by the National Science Foundation and housed in the 91�� Center for Collaborative Synthesis in Archaeology in the Institute of Behavioral Science to create the database of housing floor area measurements from sites around the world.

Scholars then examined patterns of inequality shown in the data and studied them in the context of other measures of economic productivity, social stability and conflict to illuminate basic social consequences of inequality in human society, Ortman explains.

“What we did was we crowdsourced, in a sense,” Ortman says. “We put out a request for information from archaeologists working around the world, who knew about the archaeological record of housing in different parts of world and got them together to design a database to capture what was available from ancient houses in societies all over world.”

Undergraduate and graduate research assistants also helped create the database, which contains 55,000 housing units and counting from sites as renowned as Pompeii and Herculaneum, to sites across North and South America, Asia, Europe and Africa. “By no stretch of the imagination is it all of the data that archaeologists have ever collected, but we really did make an effort to sample the world and pull together most of the readily available information from excavations, from remote sensing, from LiDAR,” Ortman says.

The housing represented in the data spans non-industrial society from about 12,000 years ago to the recent past, generally ending with industrialization. The collected data then served as a foundation for 10 papers in the PNAS Special Feature, which focus on the archaeology of inequality as evidenced in housing.

Housing similarities

In their introduction to the Special Feature, Ortman, Kohler and Bogaard note that “economic inequality, especially as it relates to inclusive and sustainable social development, represents a primary global challenge of our time and a key research topic for archaeology.

In the PNAS Special Feature published Monday, researchers from around the world describe evidence of inequality found in archaeological data of housing size. (Cover image: Johnny Miller/Unequal Scenes)

“It is also deeply linked to two other significant challenges. The first is climate change. This threatens to widen economic gaps within and between nations, and some evidence from prehistory associates high levels of inequality with lack of resilience to climatic perturbations. The second is stability of governance. Clear and robust evidence from two dozen democracies over the last 25 years that links high economic inequality to political polarization, distrust of institutions and weakening democratic norms. Clearly, if maintenance of democratic systems is important to us, we must care about the degree of wealth inequality in society.”

Archaeological evidence demonstrates a long prehistory of inequality in income and wealth, Ortman and his colleagues note, and allows researchers to study the fundamental drivers of those inequalities. The research in the Special Feature takes advantage of the fact “that residences dating to the same chronological period, and from the same settlements or regions, will be subject to very similar climatic, environmental, technological and cultural constraints and opportunities.”

Several papers in the Special Feature address the relationship between economic growth and inequality, Ortman says. “They’re thinking about not just the typical size of houses in a society, but the rates of change in the sizes of houses from one time step to the next.

“One thing we’ve also done (with the database) is arrange houses from many parts of the world in regional chronological sequences—how the real estate sector of past societies changed over time.”

The papers in the Special Feature focus on topics including the effects of land use and war on housing disparities and the relationship between housing disparities and how long housing sites are occupied. A study that Ortman led and conducted with colleagues from around the world found that comparisons of archaeological and contemporary real estate data show that in preindustrial societies, variation in residential building area is proportional to income inequality and provides a conservative estimator for wealth inequality.

“Our research shows that high wealth inequality could become entrenched where ecological and political conditions permitted,” Bogaard says. “The emergence of high wealth inequality wasn’t an inevitable result of farming. It also wasn’t a simple function of either environmental or institutional conditions. It emerged where land became a scarce resource that could be monopolized. At the same time, our study reveals how some societies avoided the extremes of inequality through their governance practices.”

The researchers argue that “the archaeological record also shows that the most reliable way to promote equitable economic development is through policies and institutions that reduce the covariance of current household productivity with productivity growth.”

GINI Project data, as well as the analysis program developed for them, will be available open access via the Digital Archaeological Record.

Counting hidden deaths at the U.S.’s most dangerous border crossing

CU PhD candidate Chilton Tippin working to document migrant mortality in El Paso

With the desert sun beating down on the jagged trails of Mount Cristo Rey just outside El Paso, Texas, Chilton Tippin, a PhD candidate in cultural anthropology at the 91��, wipes sweat from his brow. His backpack is weighed down with bottles of water and food—not for himself, but for the people his research group expects to find hiding in the desert.

In the distance, he sees groups of migrants who just crossed the Mexican border, many of them exhausted and injured, pursued by Border Patrol agents on horseback and in helicopters.

91�� PhD candidate Chilton Tippin spent the summer of 2024 documenting the crisis at a deadly crossing point along the U.S.-Mexico border.

Tippin recalls this almost-daily scene on the mountain, a pilgrimage site that has become the deadliest crossing point along the U.S.-Mexico border.

He spent the summer of 2024 documenting the regional crisis. Though he originally expected to study the environmental impact of the Rio Grande, the unfolding humanitarian crisis was too important to ignore.

“My dissertation is about the Rio Grande, but since the river has been turned into a border and become heavily militarized, it has become a site for a lot of violence and death,” he says.

Yet, when Tippin tried to gather data on how many migrants were dying in the El Paso region, he ran into another problem: bureaucratic stonewalls. Many deaths, he discovered, weren’t being officially counted at all.

Without accurate data, the full scale of the crisis in El Paso is obscured, he says, and over the course of his fieldwork, Tippin saw how systemic failures, political pressure and logistical challenges combine to erase countless migrant deaths from public view.

He’s on a mission to change that.

Life and death on Mount Cristo Rey

“We would go up the mountain regularly,” Tippin recalls, “because a lot of the migrants and undocumented people trying to sneak across would be staged just on the Mexican side of the border.”

Mount Cristo Rey, the northernmost peak of the Sierra Juárez mountain range, is famous for the 29-foot-tall statue of Jesus on the Cross at its summit. With roughly two-thirds of the mountain in Texas and the rest in Mexico, it has also become a major hotspot for border crossings.

“When we would approach, often there were 20 or 30 people just sitting there in the desert with no shade, and it’d be 110 degrees (F). They would come running to us, and we would drop our backpacks and hand out 50 water bottles and any food we could carry,” Tippin says.

The migrants he and his team encountered weren’t just battling the elements. Many had endured days or weeks of travel, cartel-controlled smuggling routes and the fear of being caught and detained, or worse.

“Because of the whole process of being chased by Border Patrol in the desert, where the heat is up to 115 degrees, people are malnourished, depleted and exhausted,” Tippin says. “Then they try to swim across the river, and they’re drowning. Or they’re going out into the desert and getting lost and succumbing to dehydration and heat illness.”

The mountain itself is a paradox, both a path to safety and a trap ready to spring. The rugged terrain provides cover from Border Patrol and makes expeditions up the slopes more difficult, but it also means there’s no easy escape if something goes wrong.

“The mountain itself is such a surreal landscape,” Tippin recalls. “We often felt like we were in The Matrix or The Twilight Zone because we could be up there just kind of walking on the trails, and people are getting chased and detained and tackled.

“It’s also weird because it’s a religious place. But at the same time you’re moving through that landscape, people are running for their lives.”

The cartel’s grip on the El Paso region

For many of the migrants Tippin encountered, danger didn’t begin on the mountain. In Ciudad Juárez, just across the border from El Paso, the Juárez Cartel has taken control of border crossings, turning human smuggling into a lucrative extension of its drug trade.

“I don’t want to push this idea that the violence is just a ‘Mexico problem.’ But the reality is that people wouldn’t be forced into these cartel-run routes if they had a safe, legal way to cross the border,” Tippin says.

Cartel smugglers, known as coyotes, lead groups of migrants across the border, often charging thousands of dollars per person. In the mountains, the cartel stations lookouts to monitor movements of migrant groups and evade the Border Patrol.

“They are just posted up on the peaks, watching for agents and guiding groups through,” Tippin says. “Border Patrol would try to menace them with helicopters, but they never actually go up there because it’s too dangerous.”

Even for individuals who make it safely across the border, the ordeal often isn’t over. Many are sent right back into cartel-controlled territory, where they face violence, extortion or death.

“That’s the deadly dynamic,” Tippin says. “People cross, they get pushed back and then they get extorted again. Women get assaulted. Families get separated. And they keep trying, because what choice do they have?”

The deaths no one wants to count

When the official numbers of migrant deaths didn’t match what Tippin was seeing on the ground, he quickly realized documenting the crisis would be harder than expected.

“I went through the whole summer filing open records requests, and I was told, ‘We don’t count migrants,’” he recalls. “Then when I tried to get autopsy reports, they said that if I wanted to see the records of drowning victims, it would cost over $4,000. And if I wanted a broader dataset—covering deaths in the desert as well—I got a bill for over $100,000.”

Tippin notes that U.S. Customs and Border Protection (CBP) reporting rules can be obscure, which may lead to underreporting. If a migrant drowns in the El Paso canals or is found in the desert by local first responders, the Texas National Guard or civilians, they aren’t counted in the official data. If they die in a hospital after being rescued, they also don’t make the list. Even if remains are discovered by CBP personnel but the person was not in custody, guidelines state the death isn’t reportable.

As a result, the official data can be off by hundreds—if not thousands—of deaths.

This isn’t just an oversight, Tippin notes. It’s part of a pattern. No More Deaths, a volunteer organization, exposed years of under-counted fatalities, with actual migrant deaths sometimes exceeding CBP’s reports by two to four times.

For Tippin, the answer to why this happens is simple: Acknowledging the full scale of the crisis would shed light on the deadly consequences of U.S. border policies.

“I think that the deaths go uncounted because it’s inconvenient for the whole political and bordering apparatus to have it be known that, as a consequence of their policies and their practices, hundreds of people are dying in the United States, in the deserts and in the rivers that form the border,” he says.

Fighting for the truth

Despite the resistance, Tippin and several grassroots organizations aren’t giving up the fight. They’re using the limited data they have, as well as anecdotal fieldwork, to push for policy changes, local resolutions and new initiatives aimed at tracking and preventing migrant deaths.

“It’s such a preventable public health trend,” he says, “and the way we attempt to address problems such as these is to gather data on them.

“We need to make what’s happening apparent and use the data to strategically implement interventions that could help reverse this alarming and tragic trend.”

One organization in Tucson, Arizona, Humane Borders, is using this approach. It works directly with the local medical examiner’s office to gather precise data on migrant deaths. That data is then used to strategically place water stations in high-risk areas.

Tippin and others want to replicate that success in El Paso, but without government cooperation, progress is slow.

“The medical examiner’s office in Tucson works with humanitarian groups,” he explains. “In El Paso, they won’t even meet with us. That’s the difference.”

But activists like Tippin aren’t waiting for permission. They continue to document deaths, advocate for policy changes and pressure local officials to increase transparency.

Recently, Tippin and his research team went before the El Paso County commissioners, pushing them to acknowledge the crisis and demand more transparency from the medical examiner’s office.

“We recently had them pass a resolution decrying all the deaths in El Paso. It’s a step in the right direction, but we need more than words—we need action,” he says.

In the El Paso region, migrants continue to suffer and die from preventable causes. The work to help them is slow, and the resistance is strong. Yet Tippin and others refuse to back down because, ultimately, it’s not about numbers.

“These aren’t just statistics,” he says. “These are people. And until we start treating them as such, nothing is going to change.”

91�� anthropologist says ‘Lucy’ is pivotal to the science of human origins a half-century after her discovery

A half-century after her discovery in Ethiopia, the 3.2-million-year-old hominin popularly known as “Lucy” remains a critical touchstone in humanity’s understanding of its origins.

Matt Sponheimer, a 91�� professor of anthropology, notes that the Australopithecus afarensis skeleton known as Lucy is "instantly recognizable in a world awash in fossils."

Officially labeled A.L.288-1, Lucy extended humanity’s ancient history by almost a million years, and she remains a standard to which decades of discoveries have been compared.

“Lucy is instantly recognizable in a world awash in fossils,” says Matt Sponheimer, a 91�� professor of anthropology whose research focuses on the ecology of early hominins from the African continent. “She is in many ways a touchstone.”

American anthropologist Donald Johanson first noticed what appeared to be a human-like elbow while out looking for fossils with a graduate student on Nov. 24, 1974, at Afar, Ethiopia, and soon spied multiple fragments nearby. He and his team eventually unearthed 47 remarkably well-preserved bones—about 40% of a complete skeleton—including skull fragments, a mandible with teeth, ribs and pieces of an arm, leg, pelvis and spine.

Lucy was eventually revealed to be an early hominin—a member of a hominid subfamily that includes humans, chimps and bonobos—with a brain about one-third to one-fourth the size of modern humans who walked upright. Research suggests that Lucy’s kind thrived in a wide range of ecosystems, from woodlands to grasslands and riverine forests.

Sharing characteristics of both Australopithecus africanus, a previously discovered hominin from South Africa, and chimpanzees, Lucy was assigned to a new species, Australopithecus afarensis.

Lucy's well-preserved skeleton, comprising about 40% of her body, provided unprecedented insights into early hominin anatomy.

A singular discovery

When Lucy was discovered, she was “singular,” Sponheimer says. But subsequent research has uncovered hundreds of fossils from Australopithecus afarensis as well as other distinct hominin species and footprints of bipedal hominins preserved in volcanic ash.

Despite fifty years of major discoveries, anthropological consensus still considers Lucy a likely ancestor to modern humans.

Beyond her monumental significance to the scientific understanding of human origins, Lucy has played a key role in educating people about evolution and anthropology.

Her fame and wide recognition have helped spur generations of children’s and students’ interest in the field. Johanson’s best-selling 1981 book, Lucy: The Beginnings of Humankind, is still widely read by popular audiences.

“A huge number of anthropologists were inspired by that book,” Sponheimer says. “When I read it, I remember thinking, ‘Wow, this is the kind of thing I would like to pursue.’”

Years later, he considers not just anthropology but also research in the broader humanities, arts and sciences to be critical to human knowledge and flourishing. He cautions against the unforeseen consequences of American culture’s gradual shift to a more instrumental, economic view of the world.

“Exploring is part of what it means to be human. What’s more human than experiencing wonder and trying to understand the world around us? Tens of thousands of years of archaeology teaches us that. Channeling exploration into a narrow economic field of vision misses the point, I think, and is ultimately self-defeating on the economic front,” he says.

91�� anthropology PhD candidate Sabrina Bradford has been learning what’s on the menu for grizzlies in Montana

If you’re ever heading to Montana’s backcountry, you’d be hard pressed to find a better guide than Sabrina Bradford, a 91�� PhD candidate in biological anthropology.

Bradford has spent more than a decade in the area’s countryside, mostly on horseback, studying conflict between humans and wildlife, social-ecological systems, livestock damage and the grizzly-bear diet.

Lately she’s been getting noticed for that last item.

Anthropology PhD candidate Sabrina Bradford (left) wrote Grizzly Bear Foods: Reference Guide to the Plants, Animals, and Fungi in the Montana Grizzly Bear's Diet, published by Montana Fish, Wildlife and Parks.

This fall, Montana Fish, Wildlife and Parks published her new 100-page book, Grizzly Bear Foods: Reference Guide to the Plants, Animals, and Fungi in the Montana Grizzly Bear's Diet, which will be part of the state’s “bear aware” education program for the public in 2025.

“I saw a lot about how grizzlies used the landscape,” says Bradford, who sometimes has ridden 20 miles a day in the backcountry doing research and working as a guide and bear education specialist. “I took plenty of photos of grizzly bear signs―areas where it looked like a tiller had rolled through the soil, over rocks and torn up trees. I wanted people to be able to see the landscape similar to the way I did. It’s really important to me that the public understands what bears are actually doing on the landscape.”

Of course, that landscape is a massive buffet for grizzlies, whose four food groups are plants, animals, fungi and trash from humans. A few specific examples of their diet: grasses, shrubs, seeds and fruits of trees, mushrooms, ducks, bird eggs, trout, salmon, squirrels, beaver, moose, bison, elk, deer, bighorn sheep, ants, termites and bees.

Bradford, who graduates this month, says grizzlies serve an important role as seed dispersers within the ecosystem there, and many of the shrubs grizzlies eat produce berries (e.g. huckleberry, raspberry, serviceberry, grouse whortleberry, buffaloberry) that are dispersed via scat.

‘Pretty cool animals’

“Bears are pretty cool animals,” Bradford says. “They have incredible spatiotemporal memory [they can recall where and when food was presented], and they use social learning. Mom teaches her cubs food acquisition strategies. This is key for people to understand, those who question why cubs were removed from an area as well as when the mother is removed for dumpster diving. She’s just teaching her cubs how to access a reliable food resource.”

Bears are also not above stealing other animals’ food stash, an activity called kleptoparasitism.

“People who hike in grizzly country with their dogs off the leash say their dog will protect them. That doesn’t really work,” Bradford explains. “Kleptoparasitism is one of the food-source acquisition strategies grizzlies use, and they’ll steal food from packs of wolves. Wolves will yield to grizzly bears, and your dog is nowhere near as tough as a pack of wolves.”

Bradford says while she’s seen many grizzlies, she’s never had to use her bear spray. Her advice to avoid attacks: “Realize that the human voice is the most powerful deterrent out there, not radios or bear bells. Talk loud in areas of low visibility so the bears can hear you coming. It’s critical to understand that you shouldn’t surprise a bear, that they’ll do anything to protect their cubs. And be aware of magpies or ravens in the forest because they’re a sign you might be hiking up on a carcass.”

And while grizzlies’ sense of hearing is strong, their sense of smell is astounding. “The size of the olfactory bulb, the part of the brain that processes scent information in grizzlies, is more than five times larger than humans’ olfactory bulb.” She advises people to sleep in clothes they haven’t cooked in: “Just because you can’t smell food on your clothes doesn’t mean bears can’t.”

Bradford adds that there is a common misunderstanding that grizzlies are looking to wipe out the first person they see and that livestock producers want to kill all grizzlies.

“That isn’t true,” she says. “Yes, livestock loss to grizzlies does occur, but ranchers I interviewed said over 80% of the grizzlies out there never cause any trouble. And other ranchers reported that it’s common to see grizzlies grazing grass in the same fields that the cattle use.”

She recalls one rancher telling her, “’Wildlife is embedded deep in our traditions. We don't hate grizzly bears; they're amazing animals. I don't want to give up all I have to the grizzly bear but I'm willing to share it.’”
