The origins and early evolution of primates is shrouded in mystery due to lack of fossil evidence. They are believed to have split from plesiadapiforms in Eurasia around the early Eocene or earlier. The first true primates so far found in the fossil record are fragmentary and already demonstrate the major split between strepsirrhines and ...

Sexual reproduction may have increased the rate of evolution. [52] By 1000 Ma First non-marine eukaryotes move onto land. They were photosynthetic and multicellular, indicating that plants evolved much earlier than originally thought. [53] 750 Ma Beginning of animal evolution. [54] [55] 720–630 Ma
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
For example, ape has been used either as an alternative for monkey or for any tailless, relatively human-like primate. [5] [6] Sir Wilfrid Le Gros Clark was one of the primatologists who developed the idea of trends in primate evolution and the methodology of arranging the living members of an order into an "ascending series" leading to humans.

The Monkey Island of Pomraning and Simon's youth was a fraction of the size of today's island. The island is currently about 1,800 feet long and 800 feet wide.
New World monkeys are small to mid-sized primates, ranging from the pygmy marmoset (the world's smallest monkey), at 14 to 16 cm (5.5 to 6.5 in) and a weight of 120 to 190 g (4.2 to 6.7 oz), to the southern muriqui, at 55 to 70 cm (22 to 28 in) and a weight of 12 to 15 kg (26 to 33 lb).
The Infinite Monkey Theorem hypothesizes that, given a typewriter and an infinite amount of time, a monkey could in theory produce the full works of William Shakespeare. It has long been used to ...
