One more reason why evolution is better than your myth:
Title of the article: “Sleeping around gave early humans immune boost from Neanderthals, Denisovans”
The ancestry of modern humans has gotten much more interesting in recent years. Completion of the Neanderthal genome came with a bit of a surprise: they may be extinct, but many modern humans carry pieces of their genome, a sign that our ancestors had some rather significant interactions with them. About the same time, we learned that there was another group of archaic humans called the Denisovans present in Asia at the same time; nine months later, we learned that our ancestors had slept with them, too.
The evidence came in the form of DNA that was unevenly distributed within modern human populations. Modern humans had gotten their start in Africa, but Neanderthal or Denisovan DNA is rare or absent in African populations. Instead, it’s more common in Asian and European populations, which suggests that interbreeding only took place after modern humans had migrated out of Africa.
