News in Brief
Northeastern Siberia hosted migrations of three consecutive ancient populations that created a genetic framework for Siberians and Native Americans today, scientists say.
While each incoming population largely replaced people already living there, mating between newcomers and old-timers also occurred, conclude evolutionary geneticist Martin Sikora of the University of Copenhagen and...
DNA from a 9,000-year-old baby tooth from Alaska, the oldest natural mummy in North America and remains of ancient Brazilians is helping researchers trace the steps of ancient people as they settled the Americas. Two new studies give a more detailed and complicated picture of the peopling of the Americas than ever before presented.
People from North America moved into South America in at...

Talk about blended families. A 13-year-old girl who died about 50,000 years ago was the child of a Neandertal and a Denisovan.
Researchers already knew that the two extinct human cousins interbred (SN Online 3/14/16). But the girl, known as Denisova 11 from a bone fragment previously found in Siberia’s Denisova Cave, is the only first-generation hybrid ever found.
Humans’ gift of gab probably wasn’t the evolutionary boon that scientists once thought.
There’s no evidence that FOXP2, sometimes called “the language gene,” gave humans such a big evolutionary advantage that it was quickly adopted across the species, what scientists call a selective sweep. That finding, reported online August 2 in Cell, follows years of debate about the role of FOXP2...
Commercials abound for DNA testing services that will help you learn where your ancestors came from or connect you with relatives. I’ve been interested in my family history for a long time. I knew basically where our roots were: the British Isles, Germany and Hungary. But the ads tempted me to dive deeper.
Previous experience taught me that different genetic testing companies can yield...
Michael Douglas, a new resident of southern Maryland, credits genetic testing for helping him find his heritage — and a family he knew very little about.
Douglas, 43, is adopted. He knew his birth mother’s name and had seen a birth certificate stating his birth name: Thomas Michael McCarthy. Over the years, Douglas had tried off and on to find his birth family, mostly by looking for his...
