The tarsian hypothesis of Jones, which he held to from 1918 [14] until his death, claimed that the human line of development did not diverge from that of apes or monkeys but from much earlier, before the Oligocene 30 million years ago, from a common ancestor with a primitive primate group of which the only other survivor is the Tarsier.

Films about primates, eutherian mammals. There are 190–448 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were described in the first decade of the 2000s, and eleven since 2010. Primates are divided into two distinct suborders.
You've probably heard the popular claim that humans only tap into about 10 percent of their brain power. Neurologists have debunked that urban legend countless times in the past, with many calling ...
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.
The savannah hypothesis (or savanna hypothesis) is a hypothesis that human bipedalism evolved as a direct result of human ancestors' transition from an arboreal lifestyle to one on the savannas. According to the hypothesis, hominins left the woodlands that had previously been their natural habitat millions of years ago and adapted to their new ...
