Scientists Recreate Genome of Ancient Human Ancestor

Scientists have recreated part of the genetic code of an extinct, shrewlike creature that is thought to have been the most recent common ancestor of most placental mammals, including humans.

Placental mammals give birth to live young, and they descended from a common ancestor scientists simply call the “boreoeutherian ancestor.” The creature scurried about the woodlands of Asia more than 70 million years ago.
