Meet Homo habilis

less than 1 minute read

This station has several of the key cranial specimens of Homo habilis, together with Sts 5, the representative of Australopithecus africanus. The H. habilis specimens include:

  • KNM-ER 1470, from Koobi Fora, Kenya, 1.9 million years old.
  • KNM-ER 1813, from Ileret, Kenya, 1.65 million years old.
  • OH 24, from Olduvai Gorge, Tanzania, 1.8 million years old.

Another skull, KNM-ER 1805, is also included here. This skull may also represent H. habilis, or it may be something else.

What to do: Examine the H. habilis crania compared to A. africanus and early Homo erectus. What makes these skulls more like Homo than Australopithecus?

KNM-ER 1470 and KNM-ER 1813 are very different in size. Are they male and female of the same species, or do you think they are different species?

What is KNM-ER 1805?
