Hard-won genetic clues from the bones of Philistines, a people known from the Old Testament for their battles with Israelites, have taken some of the mystery out of their hazy origins.

DNA extracted from the remains of 10 individuals buried at Ashkelon, an ancient Philistine port city in Israel, displays molecular links to ancient and modern populations in the eastern Mediterranean,...

Neandertals had evolutionary stamina. An unbroken genetic line of the jut-jawed, powerfully built human relatives inhabited Europe for at least 80,000 years until dying out around 40,000 years ago, scientists say.

DNA extracted from fossils of two roughly 120,000-year-old European Neandertals displays closer genetic links to 40,000-year-old European Neandertals than to a Siberian...

After police used DNA sleuthing techniques to arrest a teenage suspect in Utah accused of assault, a public genealogy website shut off most police access in May, following public outcry. That move by GEDMatch to protect the privacy of its users could backfire, some experts warn, creating more privacy issues, not fewer. 

Forensic genetic genealogy — the use of genetic databases by police...

Normal isn’t always normal. A new study finds that large groups of cells in healthy tissues carry mutations, including ones tied to cancer.

About 95 percent of healthy people had patches of mutated cells in at least one of the 29 tissues examined, including kidney, muscle and liver, researchers report in the June 7 Science. Most of those mutations found in the 488 people in the study are...
