Page "Ardipithecus" Paragraph 3

Like most primitive, but unlike all previously recognized hominins, it had a grasping or big toe adapted for locomotion in the trees.

However, its describers claim that other features of its skeleton reflect adaptation to bipedalism on the ground as well.

Like later hominins, Ardipithecus had reduced canine teeth.

Its brain was small and comparable in size to that of the modern chimpanzee.
