A new study published in PLOS ONE by a team of researchers at the University of Technology in eindhoven, the Netherlands, suggests that The main cause of Neanderthal extinction was inbreeding, not Homo sapiens. It is believed that Because Homo sapiens were smarter or larger, they invaded Europe and the Near East, where Neanderthals lived, leading to nemesutt stoic extinction.
To do this, the researchers built a model that simulated 10,000 years of Neanderthal population, taking into account three different factors: first, inbreeding, which impaired the adaptability of the population.
The second is the Allee effect (a positive relationship between individual fitness and population density at low density), i.e. because of limited spouse choices, small groups cannot grow, have too few populations to hunt, and cannot raise children.
The third factor is the natural fluctuation sq. birth rate, mortality rate and sex ratio.
These models suggest that although Neanderthals could not have been extinct simply because of inbreeding, inbreeding combined with the Allee effect and natural changes in populations could be achieved.
When Homo sapiens arrived, the number of Neanderthals was between 10,000 and 70,000, and they were not necessary for Neanderthal extinction, the researchers said.
