Nuclear war is an often-predicted cause of the extinction of humankind. [1]Human extinction 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 Denisovans or Denisova hominins(/ dəˈniːsəvə / də-NEE-sə-və) are an extinct species or subspecies of archaic human that ranged across Asia during the Lower and Middle Paleolithic, and lived, based on current evidence, from 285 to 25 thousand years ago. [ 1 ] Denisovans are known from few physical remains; consequently, most of what ...
The following tables give an overview of notable finds of hominin fossils and remains relating to human evolution, beginning with the formation of the tribe Hominini (the divergence of the human and chimpanzee lineages) in the late Miocene, roughly 7 to 8 million years ago. As there are thousands of fossils, mostly fragmentary, often consisting ...
In over 4.5 billion years of Earth’s existence and millions of years of human evolution, we’ve seen civilizations rise and fall, survived wars and famines, and made discoveries that have ...
Extinction: The Facts is a 2020 documentary film by the natural historian David Attenborough which aired on the BBC.

Homo heidelbergensis (also H. erectus heidelbergensis, [ 1 ]H. sapiens heidelbergensis[ 2 ]) is an extinct species or subspecies of archaic human which existed during the Middle Pleistocene. It was subsumed as a subspecies of H. erectus in 1950 as H. e. heidelbergensis, but towards the end of the century, it was more widely classified as its ...
The early modern human vocal apparatus is generally thought to have been the same as that in present-day humans, as the present-day variation of the FOXP2 gene associated with the neurological prerequisites for speech and language ability seems to have evolved within the last 100,000 years, [125] and the modern human hyoid bone (which supports ...
t. e. Human history is the record of humankind from prehistory to the present. Modern humans evolved in Africa around 300,000 years ago and initially lived as hunter-gatherers. They migrated out of Africa during the Last Ice Age and had populated most of the Earth by the end of the Ice Age 12,000 years ago.
