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.
[99] [100] Modern Europeans of today bear no trace of the genomes of the first Homo Sapiens Europeans, but only of those from after the ecological crisis of 38,000 BCE. [101] Modern humans then repopulated Europe from the east after the eruption and the ice age that took place from 38,000 to 36,000 BCE. [102]
Homo sapiens were less vulnerable to Neanderthal diseases, partly because they had evolved to cope with the far higher disease load of the tropics and so were more able to cope with novel pathogens, and partly because the higher numbers of Homo sapiens meant that even devastating outbreaks would still have left enough survivors for a viable ...
The trove is the oldest Homo sapiens DNA ever documented, scientists say. ... Some, such as those related to the immune system, were beneficial to humans as they lived through the last ice age ...
Around 60,000 years ago, during the middle of an ice age, it was extremely cold in the far north, but ice sheets sucked up much of the moisture in Africa, making the continent even drier and droughts much more common. The result was a genetic bottleneck, pushing Homo sapiens to the brink of
A Homo fossil was found near some Oldowan tools, and its age was noted at 2.3 million years old, suggesting that maybe the Homo species did indeed create and use these tools. It is a possibility but does not yet represent solid evidence. [ 195 ]
Skull of Cro-Magnon 1. Cro-Magnons or European early modern humans (EEMH) were the first early modern humans (Homo sapiens) to settle in Europe, migrating from western Asia, continuously occupying the continent possibly from as early as 56,800 years ago.
Fossils of early Homo sapiens were found in Qafzeh and Es-Skhul Caves in Israel and have been dated to 80,000 to 120,000 years ago. [50] [51] These humans seem to have either become extinct or retreated back to Africa 70,000 to 80,000 years ago, possibly replaced by southbound Neanderthals escaping the colder regions of ice-age Europe.
