This tells them how long it’s been since the individuals shared ancestors.Comparison of DNA between you and your sibling would show relatively few mutational differences because you share ancestors – mom and dad – just one generation ago.At that time, a population – the common ancestors of both human groups – separated geographically and genetically.Some individuals of the group migrated to Eurasia and over time evolved into Neanderthals.DNA holds the story of our ancestry – how we’re related to the familiar faces at family reunions as well as more ancient affairs: how we’re related to our closest nonhuman relatives, chimpanzees; how mated with Neanderthals; and how people migrated out of Africa, adapting to new environments and lifestyles along the way.And our DNA also holds clues about the timing of these key events in human evolution.Analyzing DNA from present-day and ancient genomes provides a complementary approach for dating evolutionary events.

The case of Neanderthals illustrates how the mutation and recombination clocks can be used together to help us untangle complicated ancestral relationships.However, there are millions of differences between humans and chimpanzees; our last common ancestor lived over six million years ago.Recombination, also known as crossing-over, is the other main way DNA accumulates changes over time.However, these methods require ancient remains to have certain elements or preservation conditions, and that is not always the case.Moreover, relevant fossils or artifacts have not been discovered for all milestones in human evolution.
