It’s been revealed that experts managed to find the reasons that might have led to the extinction of Neanderthals.
Ancient-origins website writes that analysts who used population models now believe that inbreeding and the internal dynamics of the small populations have resulted in their extinction.
In other words, this could mean something more: the modern humans did not necessarily cause the extinction of this species of “archaic humans” as the online publication’s article notes.
This new research was led by a group at the University of Eindhoven, in the Netherlands and it sought to test if the internal dynamics that operate in small populations might have led to the elimination of the Neanderthals, says the study that has been published in PLOS ONE.
The study aimed to establish is the decline had anything to do with the demographic factors or the mating behavior.
It seems that the global population of the species was small and there were about 5,000-70,000 individuals, according to the study mentioned above.
Demographic decline and inbreeding
Statistical tools have been used in this study in order to find out the causes of the population’s decline.
The website mentioned above cites the info from The Daily Mailand Science Alert, and they write that according to The Daily Mail , “the researchers modeled how their populations might have fared over 10,000 years”.
Experts wanted to make the findings reliable, and they also used modern human hunter-gathering groups.
They reportdly “ran population simulations for Neanderthal societies of various starting sizes (from 50 individuals to 100, 500, 1,000, or 5,000),” according to Science Alert.
The second factor is considered the allee effect
The second factor that was analyzed in the study was something called the allee effect. This is when a small population does not reproduce itself because of an inability to secure enough resources, and there is a limited choice of mates.
