Timing

Timing of appearance of the difference in the Hominin Lineage as a defined date or a lineage separation event. The point in time associated with lineage separation events may change in the future as the scientific community agrees upon better time estimates. Lineage separation events are defined in 2017 as:

the Last Common Ancestor (LCA) of humans and old world monkeys was 25,000 - 30,000 thousand (25 - 30 million) years ago
the Last Common Ancestor (LCA) of humans and chimpanzees was 6,000 - 8,000 thousand (6 - 8 million) years ago
the emergence of the genus Homo was 2,000 thousand (2 million) years ago
the Last Common Ancestor (LCA) of humans and neanderthals was 500 thousand years ago
the common ancestor of modern humans was 100 - 300 thousand years ago

Possible Appearance:

40,000 thousand years ago

Probable Appearance (Lineage Separation Event):

Last Common Ancestor of Humans and Chimpanzees

Definite Appearance:

200 thousand years ago
