A new study shows that early Homo sapiens in Europe co-exist with Neanderthals in some regions where there are sufficient herbivores to support both populations.
Herbivore carrying capacity In ecology, there’s an idea called the competitive exclusion principle, which states that competitive species cannot coexist over a long period of time.
It’s an old idea, established by Thomas Malthus and subsequently built upon by Charles Darwin.
However, more recent research complicates the idea, showing that complete competitors can coexist if there are enough resources to keep things balanced.
When it comes to our expansion out of Africa, which probably started around 60,000 years ago, the traditional assumption was that our ancestors competed with other early human species for scarce resources.
But again, the reality appears to be far more complicated.
It seems the extent of this mass extinction did not occur all at once.
In fact, there was a kind of mosaic of cultural and biological overlap between our two species for
