Hominins have canines that are: australopithecines compares hominid traits to those of other catarrhine primates both living and extinct, presenting a new hominization model that does not depend solely on global climate change, but on predictable trends observed in catarrhines. Ardipithecus essentially falsifies such models, because extant apes are highly derived relative to our last common ancestors. It had . Free.

There is no doubt that one of the major drivers (selective pressures) in hominin evolution is the environment. This suggests that primate (hominid) behavior and socio-ecology do not exhibit higher levels of homoplasy than other biological data sets.
