Various smaller-, bipedal hominins.

These include members of genus genus Australopithecus as well as members of genus .

The australopiths lived from at most about 4.5 to 1.5 million years ago. Together they are considered to be a paraphyletic grouping because of the omission of their descendant clade, genus Homo.
