An ancestral human species faced a startling population bottleneck and teetered on the brink of extinction around 800,000 years ago, according to new research.

Muyi Aina, Executive Director of the NPHCDA, says Nigeria needs $1 billion to secure vaccines for its population.

A study of the inner ear bones of Neanderthals shows a significant loss of diversity in their shape around 110,000 years ago, suggesting a genetic bottleneck that contributed to Neanderthals' decline.

This represents a severe population bottleneck. This was seen genetically through increased runs of homozygosity within the genome, caused when both parents contribute nearly identical chromosomes ...

An ‘ancestral bottleneck’ took out nearly 99 percent of the human population 800,000 years ago Only 1,280 breeding individuals may have existed at this dramatic era of human history. By Laura ...

The population of early humans dwindled to around 1,280 individuals during a time of dramatic climate change and remained that small for about 117,000 years, the study said.

Before the bottleneck, the scientists concluded, the population of our ancestors included about 98,000 breeding individuals. It then shrank to fewer than 1,280 and stayed that small for 117,000 years.

The genetic data suggest that between 813,000 and 930,00 years ago, the ancestors of modern humans experienced a severe "bottleneck," losing about 98.7% of its breeding population.

What I got from the article is that a small population of 10 individuals may recover, and purge the very harmful mutations, but that their offspring will be stuck with a lot of mildly harmful ...

Almost 99% of all human ancestors may have been wiped out around 930,000 years ago, a new paper has claimed. The new research, published in the journal Science, used DNA from living people to suggest ...
