...Swanscombe.

The Swanscombe fossil from southern England, the skull of an adult female with heavy brow ridges and a large projecting face.

Identified as Homo heidelbergensis, the Swanscombe skull dates to the Hoxnian Interglacial of four hundred thousand years ago, and since this follows the extreme Anglian ice age which drove humans out of the British Isles, the Swanscombe people must represent a re-colonization.

It is among these and similar finds in Africa that the line of distinction between Homo erectus and Homo sapiens becomes dim, for one species is apparently grading imperceptibly into its successor.
