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.… read more about What Can Fossil Teeth Tell Us About Our Ancestors? »

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 in chemical… read more about Your Cells Look Young for Their Age, Compared to a Chimp’s »

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  »

In chimpanzee society, males spend their entire lives in the group where they were born, cooperating to defend their territory, while females tend to move away. But some chimp females seem less willing to cut the apron strings. New findings from researchers at Duke University and North Carolina State University show that female chimpanzees with high-ranking mothers are more likely to be homebodies. The study suggests that the perks of having a powerful mom can make it worthwhile for some females to stay and reproduce in the… read more about Female Chimps With Powerful Moms Are Less Likely to Leave Home »

If you asked Jenny Tung’s parents, “no one’s kids that they knew of went off to Africa every summer to look at monkeys.” But Tung has been doing just that since her first trip to Kenya in 2006 to study the wild baboons of Amboseli. She joined a research project that year that had been watching the same troops of free-ranging baboons within sight of Mt. Kilimanjaro since 1971, witnessing pairings, births, fights, deaths. Many generations of baboons later, the Amboseli Baboon Research Project is still going on, and… read more about Duke's Jenny Tung Wins $625k MacArthur Foundation Genius Grant »

Anyone who says females are the ‘gentle sex’ has never met a lemur. Lady lemurs get first dibs on food, steal their mates’ favorite sleeping spots and even attack males, swatting or biting those that annoy them. What gives these female primates the urge and ability to reign supreme while the meeker males give in or get out of the way? New research suggests that female lemurs’ bullying behavior may get programmed early, before birth. A Duke University study shows that a mother lemur’s hormone levels during pregnancy can have… read more about Lemur Sex Role Reversal Gets Its Start in the Womb »

DURHAM, N.C. -- A team of Peruvian and American scientists have uncovered the 18-million-year-old remains of the smallest fossil monkey ever found. A fossilized tooth found in Peru’s Amazon jungle has been identified as belonging to a new species of tiny monkey no heavier than a hamster. The specimen is important because it helps bridge a 15-million-year gap in the fossil record for New World monkeys, says a team led by Duke University and the National University of Piura in Peru. The new fossil was unearthed from an… read more about World's Smallest Fossil Monkey Found in Amazon Jungle »

DURHAM, N.C. -- Duke University scientists have given us another way to tell which endangered lemur species are most at risk from deforestation -- based on the trillions of bacteria that inhabit their guts. In a new study, researchers compared the gut microbes of 12 lemur species across the island of Madagascar, where thousands of acres of forest are cleared each year to make way for crops and pastures. The team found that some lemurs harbor microbes that are more specialized than others for the forests where they live,… read more about EvAnth Alum publishes lemur research »
