  • In 2012, a team found evidence of DNA methylation in the bones of a 26,000-year-old bison, but it wasn't clear whether it was a fluke. To find out, Rick Smith of the University of Texas in Austin, and colleagues, collected samples from 30 different human remains, ranging from 200 to 6,000 years old who were treated with a chemical that revealed where the methyl tags were when the DNA was sequenced. The epigenetic changes should therefore be detectable in other ancient remains, says Smith, who presented the findings at the American Association of Physical Anthropologists in Knoxville TN.
