How can analyzing DNA help scientists determine the amount of time that has passes since species shared a common ancestor?
In evolutionary biology, a group of organisms have common descent if they have a common ancestor. All living organisms on Earth are descended from a common ancestor or ancestral gene pool. Keep asking ChaCha!
