characteristics that lived 434 mya.
Proconsul lived about 20 mya and had a larger brain than a monkey, apelike teeth, and diet (fruit) but
monkeylike body. Proconsul was a transition arthropoid that had limbs and body proportions of a
monkey but lacked a tail like apes
Dryopithecus is an advanced chimp-size ape that may have been ancestoral to modern hominoids.
Dryopithecus lineage may have lived 15 mya and led to modern apes as well as humans.
