In 1994, Tim White announced the discovery of a new species based on a juvenile partial mandible. This was met with a great deal of debate, as juvenile fossils are well known for being morphologically deceptive. In 2009, the discovery of a large collection of non-juvenile fossils - many of them from a single specimen - validated the initial announcement. “Ardi,” as this creature has been dubbed, was found with a great deal of other fossil evidence indicative of a heavily forested paleoenvironment. Astonishingly, it was found with fossilized seeds and wood, as well as several species of non-hominin animals, including monkeys. This collection paints a vivid picture of heavy woodlands typical of a flood plain. Ardi has many features that suggest an arboreal lifestyle: long, curved phalanges, a divergent big toe, and a short palm - which points to palm walking rather than the expected knuckle-walking. This discovery could mean that knuckle-walking is not an ancestral locomotive method, but one that evolved later (and independently) in gorillas and chimps. Humans appear never to have passed through this long-assumed style of movement. In contrast to her ape-like arms, Ardi also has less pronounced canines than their predecessors and a more centrally located foramen magnum, which points to bipedalism. Based on dentition, Ardi appears to have been omnivorous, but did not regularly consume harder substances such as nuts.
