A 2015 Q&A from the Smithsonian Insider suggests that Neanderthals went extinct because of climate change. Kind of a political synchronicity: Neanderthals didn’t believe in climate change and paid the price. Humans out of Africa were more adaptive to climate change and survived.
I’m not making this up. Take a look here.
While the study is a theory, there has never been any evidence of wars between humans and Neanderthals. Quite the contrary, humans and Neanderthals mated, though there probably was no flowers or chocolates involved. So many of us now carry between 1-4 percent DNA of Neanderthal origin.
That bit of DNA might just be biting us back now as we see so many of a particular political persuasion who don’t believe in climate change. Synchronicity.
