The common ancestors of all humans are thought to have lived 2,000-3,000 years ago. The term "common ancestor" is used in the study of human genetic heritage and refers to an individual from which a group is directly descended. It is thought that anyone who was alive about 3,000 years ago is either an ancestor of everyone now on Earth or not an ancestor of anyone now on Earth.

- All people of European descent are thought to have the first Holy Ruler of Europe, Charlemagne, as a common ancestor.
- It is believed that the most common ancestor for Neanderthals lived more than 500,000 years ago, which some scientists believe could mean that Neanderthals did not contribute any genetic material to modern humans.
- The most common female ancestor of all humans is referred to by scientists as Mitochondrial Eve.
