Other similar basal primates were widespread in Eurasia and Africa during the tropical conditions of the Paleocene and Eocene. Purgatorius is the genus of the four extinct species believed to be the earliest example of a primate or a proto-primate, a primatomorph precursor to the Plesiadapiformes, dating to as old as 66 million years ago.
Hominoidea (commonly known as apes) are thought to have evolved in Africa by about 18 million years ago. Among the genera thought to be in the ape lineage leading up to the emergence of the great apes (Hominidae) about 13 million years ago are Proconsul, Rangwapithecus, Dendropithecus, Nacholapithecus, Equatorius, Afropithecus and Kenyapithecus, all from East Africa.
Proconsulidae is an early family of primates that lived during the Miocene epoch in Kenya, and was restricted to Africa.Members of the family have a mixture of Old World monkey and ape characteristics, so the placement in the ape superfamily Hominoidea is tentative; some scientists place Proconsulidae outside of Hominoidea in a separately superfamily Proconsuloidea, before the split of the ...
Proconsul is an extinct genus of primates that existed from 21 to 17 million years ago during the Miocene epoch. Fossil remains are present in Eastern Africa, including Kenya and Uganda. Four species have been classified to date: P. africanus, P. gitongai, P. major and P. meswae. The four species differ mainly in body size.
The 18-million-year-old fossil species has been considered a possible ancestor of both great and lesser apes, and of humans. The paleontologist Louis Leakey, who was one of the foremost fossil-hunters of the 20th century and a champion of evolution, said: An especially important creature was Proconsul africanus. This, many authorities once ...
In Africa in the Early Pleistocene, 1.5–1 Ma, some populations of Homo habilis are thought to have evolved larger brains and to have made more elaborate stone tools; these differences and others are sufficient for anthropologists to classify them as a new species, Homo erectus—in Africa. [71] The evolution of locking knees and the movement ...
A primate is a member of the biological order Primates, the group that contains lemurs, the aye-aye, lorisids, galagos, tarsiers, monkeys, and apes, with the last category including great apes. With the exception of humans, who inhabit every continent on Earth, most primates live in tropical or subtropical regions of the Americas, Africa and Asia.
Victoriapithecus macinnesi was a primate from the middle Miocene that lived approximately 15 to 17 million years ago in Northern and Eastern Africa. Through extensive field work on Maboko Island in Lake Victoria, Kenya, over 3,500 specimens have been found, making V. macinnesi one of the best-known fossil primates. [1]
