Abstract

The look of Toumaï The discovery of the skull known as Toumaï four years ago in Chad began a controversy. Faunal studies suggested an age close to 7 million years; a small cranium suggested chimpanzee-like brain size. The team that found Toumaï considered it to be a hominid on our side of the chimp-human divide, but others thought it more ape-like. Important finds of teeth and jaw pieces of the Toumaï species, Sahelanthropus tchadensis, now help to distance the species from apes, suggesting that it is a hominid closely related to the last common ancestor of chimps and humans. A virtual reconstruction of the Toumaï cranium provides more evidence of a close relationship to humans — and this week's cover. You are looking at the face of the earliest known hominid.
