DURHAM, N.C. -- Female baboons may not have bills to pay or deadlines to meet, but their lives are extremely challenging. They face food and water scarcity and must be constantly attuned to predators, illnesses and parasites, all while raising infants and maintaining their social status. A new study appearing April 21 in Science Advances shows that female baboons with high life-long levels of glucocorticoids, the hormones involved in the ‘fight or flight’ response, have a greater risk of dying than those with lower levels… read more about Stress and Death in Female Baboons -- as Measured by Hormones in Poop »

DURHAM, N.C. -- Some guys have it all: the muscle, the power, the high social status, the accelerated aging. But wait. Faster aging? Who wants that? For male baboons, it’s the price they pay to be at the top. New research appearing April 6 in eLife by Jenny Tung, associate professor of evolutionary anthropology and biology at Duke University, and her colleagues shows that male baboons that climb the social ladder age faster than males with lower social standing. If a male drops in social status, his estimated rate of… read more about A Male Baboon’s Dominance Gives Him Babies, but Costs Him Years »

DURHAM, N.C. -- When you think about what separates humans from chimpanzees and other apes, you might think of our big brains, or the fact that we get around on two legs rather than four. But we have another distinguishing feature: water efficiency. That’s the take-home of a new study that, for the first time, measures precisely how much water humans lose and replace each day compared with our closest living animal relatives. Our bodies are constantly losing water: when we sweat, go to the bathroom, even when we breathe.… read more about Humans Evolved to Be the Water-Saving Ape »

Duke's primate researchers travel the globe to observe wild primates, including the chimpanzees of Gombe who were first studied by Jane Goodall, and the baboons of Amboseli, who have been studied for five decades. Longevity in Humans and Chimpanzees Many humans live to see their 80s, some even reach 100. But chimpanzees rarely make it past 50, despite sharing 99% of our genetic code. While modern medicine has added years to human lifespans, a Sept. 2020 Duke study points to a more ancient explanation why humans are the long… read more about Learning From Our Closest Relatives »

DURHAM, N.C. -- Humans aren’t the only mammals that form long-term bonds with a single, special mate -- some bats, wolves, beavers, foxes and other animals do, too. But new research suggests the brain circuitry that makes love last in some species may not be the same in others. The study, appearing Feb. 12 in the journal Scientific Reports, compares monogamous and promiscuous species within a closely related group of lemurs, distant primate cousins of humans from the island Madagascar. Red-bellied lemurs and mongoose lemurs… read more about Lemurs Show There’s No Single Formula For Lasting Love »

DURHAM, N.C. -- Malaria is an ancient scourge, but it’s still leaving its mark on the human genome. And now, researchers have uncovered recent traces of adaptation to malaria in the DNA of people from Cabo Verde, an island nation off the African coast. An archipelago of ten islands in the Atlantic Ocean some 385 miles offshore from Senegal, Cabo Verde was uninhabited until the mid-1400s, when it was colonized by Portuguese sailors who brought enslaved Africans with them and forced them to work the land. The Africans who… read more about Malaria Threw Human Evolution Into Overdrive on This African Archipelago »

We use our mouths to tell stories, but we rarely ask what stories our teeth can tell. Teeth can reveal our age, what we eat, where we come from and may even give hints about how stressed we are. Can they do the same for our extinct hominid ancestors? They just might, with help from a Gordon P. Getty Grant from the Leakey Foundation to a multi-institutional team led by Dr. Richard Kay, Duke professor of Evolutionary Anthropology. This prestigious award honors scientists whose research advances multidisciplinary science… read more about What Can Fossil Teeth Tell Us About Our Ancestors? »

Tell me what you eat, and I’ll tell you your skull shape. Well, not quite, but thanks to a newly-funded grant from the Leakey Foundation, Dr. Justin Ledogar might have some good insights. Dr. Ledogar, an Assistant Research Professor in Evolutionary Anthropology, will examine dietary ecology and feeding biomechanics in a unique group of South American primates, the sakis and bearded sakis, at Brownsberg Nature Park in Suriname. Unlike most other fruit-eating primate species, these monkeys specialize on the nutrient-… read more about New Grant Sheds Light on the Evolution of Primate Skull Shape »

Viruses and bacteria not only make us sick, but have also played an important role in shaping primate evolution. Because pathogens are so large in number and replicate so quickly, we know that the immune system has had to adapt very fast to stay on a level playing field. Still, many open questions about our evolutionary history with pathogens remain. For example, what kinds of disease-causing microbes have been more important—viruses or bacteria? What changes have occurred in primate genomes to deal with these threats? Do… read more about Ph.D. Candidate Jordan Anderson Receives Leakey Foundation grant! »

We’ve all heard the term “survival of the fittest,” which scientist Charles Darwin famously coined to explain how organisms with heritable traits that give them an advantage — such as avoiding predators or beating out others for the chance to mate — are able to survive and pass on these advantageous traits to their offspring. In his talk with ClubEvMed last Tuesday, Brian Hare of Duke Evolutionary Anthropology explained key points from his new book that he co-authored with his wife and research partner, Vanessa Woods,… read more about The Evolutionary Advantage of Being Friendly »

When COVID hit last spring, many graduate students had to give up their summer plans for teaching, field research and internships. The Provost’s Office quickly pledged support, and Vice Provost Ed Balleisen spearheaded the effort to identify virtual opportunities. Experiential fellowships with eight host organizations and research assistantships with more than 20 Duke units provided summer funding and career development for all 59 Ph.D. students in need. Every student who responded to Duke’s end-of-summer evaluation would… read more about Duke Ph.D. Students Find Unexpected Benefits in an Unusual Summer »

DURHAM, N.C. -- Close bonds with the opposite sex can have non-romantic benefits. And not just for people, but for our primate cousins, too. Drawing on 35 years of data, a new study of more than 540 baboons in Amboseli National Park in Kenya finds that male baboons that have close female friends have higher rates of survival than those who don’t. Researchers have often assumed that when a male is friendlier to certain females, it’s for the reproductive perks: to better protect his offspring, or to boost his chances of… read more about Male Baboons With Female Friends Live Longer  »

DURHAM , N.C. -- Many humans live to see their 70s and 80s, some even reach 100 years old. But life is much shorter for our closest animal relatives. Chimpanzees, for example, rarely make it past age 50, despite sharing almost 99% of our genetic code. While advances in medicine and nutrition in the last 200 years have added years to human lifespans, a new study suggests there could be a more ancient explanation why humans are the long-lived primate. Part of the secret to human longevity, researchers say, may lie… read more about Your Cells Look Young for Their Age, Compared to a Chimp’s »

It’s 1 PM and you’re only halfway through a 6-hour hike, climbing in steep terrain under a 100° cloudless sky. Your water bottle is nearly empty, and you’ve heard the worst of this hike is yet to come. And then, just as you are making peace with the fact that you may collapse from dehydration at any second, you approach a small river. The germaphobe side of your brain is shouting for you not to drink from that. The dehydrated animal in you, however, is seriously considering it. What do you do? That is the question that Dr.… read more about For Lemurs, Water Holes Are a Matter of Taste »

Humans have conquered smallpox and drastically reduced child mortality rates, yet we now face problems never seen before. Conditions like heart disease, obesity, cancer, and diabetes pose serious threats to our health. How can we overcome them? The answer may lie in our past. Herman Pontzer, an associate professor of evolutionary anthropology at Duke, thinks we have something to learn by looking at hunter gatherers For most of human evolution, we had to work for our food. Recent developments like supermarkets and cities are… read more about Paleo Fact and Fiction: the Key to Being Healthy »

Even kids who are nearly grown still need a parental figure to help them navigate the long path to adulthood -- and our closest animal relatives are no exception. A new study of wild chimpanzees finds that males whose moms were present during their tween and teen years had higher odds of survival later in life, compared with their peers who lost their mothers before they finished puberty. The results appear in the February 2020 issue of the journal Behavioral Ecology and Sociobiology. Beginning in the 1960s, researchers led… read more about Adolescent Male Chimps Still Need Their Mamas  »
