| | Scientists Recreate Genome of Ancient Human Ancestor (Site not responding. Last check: 2007-11-06) |
 | | To find out what those text changes were, Blanchette, Haussler, and their colleagues used a computer program to compare and contrast the known DNA sequences of 19 of the ancestor's living relatives, including species of pig, horse, cat, dog, bat, mouse, rabbit, gorilla, chimpanzee, and human. |
 | | The results allowed the scientists to reconstruct a DNA sequence common to each species, including their common ancestor, thought to be the mother of most placental mammals. |
 | | Scientists recreated part of the genome of a later species, known simply as the "boreoeutherian ancestor," which is thought to be the most recent common ancestor of all placental mammals. |
