    DNA testing can bring families together, but gives mixed answers on ethnicity

    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...

    Genetic sleuthing again IDs a murder suspect in a cold case

    For the second time in less than a month, DNA probes of family trees in a public database have helped police catch a murder suspect.

    On May 17, detectives in Washington arrested 55-year-old William Earl Talbott II of Seatac for the 1987 double murder of Jay Cook and Tanya Van Cuylenborg. A new DNA sleuthing technique called genetic genealogy led to Talbott’s capture. His arrest came just...

    ‘First Face of America’ explores how humans reached the New World

    A teenage girl climbed into an underground cave around 13,000 years ago. Edging through the ink-dark chamber, she accidentally plunged to her death at the bottom of a deep pit.

    Rising seas eventually inundated the cave, located on Central America’s Yucatán Peninsula. But that didn’t stop scuba divers from finding and retrieving much of the girl’s skeleton in 2007.

    “First Face of...

    The story of humans’ origins got a revision in 2017

    Human origins are notoriously tough to pin down. Fossil and genetic studies in 2017 suggested a reason why: No clear starting time or location ever existed for our species. The first biological stirrings of humankind occurred at a time of evolutionary experimentation in the human genus, Homo.

    Homo sapiens’ signature skeletal features emerged piece by piece in different African...

    Mating with Neandertals reintroduced ‘lost’ DNA into modern humans

    ORLANDO, Fla. — Interbreeding with Neandertals restored some genetic heirlooms that modern humans left behind in the ancient exodus from Africa, new research suggests.

    Those heirlooms are versions of genes, or alleles, that were present in humans’ and Neandertals’ shared ancestors. Neandertals carried many of those old alleles, passing them along generation after generation, while...

    We’re more Neandertal than we thought

    Modern people of European and Asian ancestry carry slightly more Neandertal DNA than previously realized.

    About 1.8 to 2.6 percent of DNA in non-Africans is an heirloom of ancient human-Neandertal interbreeding, researchers report online October 5 in Science. That corresponds to 10 to 20 percent more Neandertal ancestry than previous estimates — and it may carry consequences for human...
