Homo habilis (lit. 'handy man') is an extinct species of archaic human from the Early Pleistocene of East and South Africa about 2.3 million years ago to 1.65 million years ago (mya). Upon species description in 1964, H. habilis was highly contested, with many researchers recommending it be synonymised with Australopithecus africanus, the only ...
Extinction: The Facts is a 2020 documentary film by the natural historian David Attenborough which aired on the BBC. It depicts the continuing sixth mass extinction, caused by humans, and the consequences of biodiversity loss and climate change. It also suggests positive action which can be taken to halt or reverse these effects.
There is disagreement if certain extinct members of the genus, namely Neanderthals, should be included as a separate species of humans or as a subspecies of H. sapiens.
