Human Evolution Chart
The human evolution chart shown below provides basic information about each of the various known hominids. All the major players of human evolution are listed, together with the approximate dates when they existed and the locations where their fossils have been found. Together, their remains represent the physical evidence for evolution of humans, human ancestors, and their relations (click here to read a history of how the idea originally arose that humans evolved from apes). When available, small pictures of the various hominid skulls are shown (to see a larger view of a skull, click on it). The chart is broken into two separate sub-charts, one for the more ancient hominids, the other for the more recent ones. Click on the gray tabs (just below at left) to change between the two.
