Sahelanthropus Tchadensis, or Toumai

Sahelanthropus tchadensis, or Toumai,

A) may be the oldest possible human ancestor yet found.
B) moves scientists close to the time when humans and apes in the Americas diverged from a common ancestor.
C) may be the oldest possible "missing link" between gorillas and Orrorin tugenensis.
D) looks more like a chimp than a human, specifically because of the placement of its foramen magnum at the base of its skull, which is farther back than in later hominins.
E) apparently lived in a habitat with scarce animal life and mountain terrain.
