Scientists have used computer analysis to reverse-engineer evolution and reconstruct much of the genome of a mammal from 80 million years ago.This little shrew-like creature is common ancestor of humans and other live mammals such as horses, bats, tigers and whales.

Are humans related to whales?

This can be explained by the following facts Whales share a more recent common ancestor with humans (Fig. 4) than they did with sharks. We predict that their closer relationship means they have more features in common, and the evidence supports this prediction.
