Nuclear war is an often-predicted cause of the extinction of humankind. [1]Human extinction or omnicide is the hypothetical end of the human species, either by population decline due to extraneous natural causes, such as an asteroid impact or large-scale volcanism, or via anthropogenic destruction (self-extinction), for example by sub-replacement fertility.
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.
Homo rhodesiensis ("Broken Hill Cranium"): dated to 324,000 to 274,000 years ago.. The category archaic human lacks a single, agreed definition. [11] According to one definition, Homo sapiens is a single species comprising several subspecies that include the archaics and modern humans.
“Whatever caused the proposed bottleneck may have been limited in its effects on human populations outside the Homo sapiens lineage or its effects were short-lived,” the two researchers said ...
Homo (from Latin homÅ 'human') is a genus of great ape (family Hominidae) that emerged from the genus Australopithecus and encompasses only a single extant species, Homo sapiens (modern humans), along with a number of extinct species (collectively called archaic humans) classified as either ancestral or closely related to modern humans; these include Homo erectus and Homo neanderthalensis.
Imagine life with no humans. One group of researchers has done exactly that -- and they even made a map to show how the world might look sans homo sapiens. SEE ALSO: California drought may ...
The spotty fossil record has left unclear the details of how Homo sapiens spread through Europe and what role our species played in the extinction of Neanderthals, who disappeared roughly 40,000 ...
After 1.5 million years ago (extinction of Paranthropus), all fossils shown are human (genus Homo). After 11,500 years ago (11.5 ka, beginning of the Holocene ), all fossils shown are Homo sapiens ( anatomically modern humans ), illustrating recent divergence in the formation of modern human sub-populations .
