Until 1980, the family ( and term ) Hominidae meant humans only; the non-human great apes were assigned to the family Pongidae.
12.
Those ancestors of the family Hominidae had already speciated from the family Hylobatidae ( the gibbons ), perhaps 15 million to 20 million years ago.
13.
A " hominid " is any member of the family Hominidae ( great apes ) which includes chimpanzees, bonobos and gorillas as well as humans.
14.
Among the Hominidae, gorillas have little female promiscuity and sperm competition and the testes are small compared to body weight ( 0.03 % ).
15.
Within the primate family Hominidae ( great apes ), gorillas ( eastern and western ) are a sister group to common chimpanzees, bonobos and humans.
16.
Loss of tail in Hominidae, loss of limbs in snakes and some lizards, loss of gills, and loss of parietal eye seem to be valid examples.
17.
Subfamilies Homininae and Ponginae are both basal within Hominidae, but given that there are no nonbasal subfamilies in the cladogram it is unlikely the term would be applied to either.
18.
The most recent common ancestor of all Hominidae lived roughly 14 million years ago, when the ancestors of the orangutans speciated from the ancestral line of the other three genera.
19.
They show that either the development of the cerebellum is tightly linked to that of the rest of the brain or that neural activities taking place in the cerebellum were important during Hominidae evolution.
20.
Evidence for the evolution of " Homo sapiens " from a common ancestor with chimpanzees is found in the number of chromosomes in humans as compared to all other members of Hominidae.
