An extreme climate event might have caused the evolutionary bottleneck. The population of our ancestors might have been reduced to just 1,280 individuals for about 117,000 years. Early human ...

The fact that we can reconstruct events from hundreds of thousands or millions of years ago just by looking at DNA today is ...

Research data suggests humans may have nearly gone extinct almost 1 million years ago, but scientists aren't sure why.

and whether natural selection during the bottleneck has accelerated the evolution of human brain,” co-author and East China Normal University evolutionary and functional genomics expert Yi-Hsuan ...

It raises the possibility that a climate-driven bottleneck helped split early humans into two evolutionary lineages — one that eventually gave rise to Neanderthals, the other to modern humans.

This severe bottleneck occurred roughly between 930,000 and 813,000 years ago, profoundly influencing the genetic makeup of today's humans. Understanding human evolution often involves looking ...

and whether natural selection during the bottleneck has accelerated the evolution of human brain,” Yi-Hsuan Pan, senior author and evolutionary and functional genomics researcher at East China ...

"The 'longevity bottleneck hypothesis' may shed light on evolutionary forces that have shaped the mammalian aging over millions of years. While humans are among the longest-living animals ...

It’s forcing the human race into what evolutionary biologists call a “bottleneck” — a period of rapid pressure that threatens cultures, customs and peoples with extinction. When college ...
