When We Met Other Human Species

  • Published: 10 July 2019
  • We all belong to the only group of hominins on the planet today. But we weren’t always alone. 100,000 years ago, Eurasia was home to other hominin species, some of which we know our ancestors met, and spent some quality time with.

    I've studied a fair amount of biogeography and I've always read that one of the defining characteristics of a species is that can only breed with members of that same species. If Homo Sapiens mated successfully with Neanderthal or Denisovans (or whoever else) then they were not really different species.

        Just think, most of us have more Neanderthal blood in our veins than Elizabeth warren has Cherokee. Thrilling to think it

            There are still other human species among us today. What would you call Patty the bigfoot? The native Americans called them human.

                                Hold on,didn’t at least some of us come from Africa? I mean life in the Tropics surely had the highest chance of producing Humanoid animals.

                                  I've always thought that Neanderthals were the descendants of the previous species of hominids that were destroyed by a nuclear disaster/war. That's why they went extinct, not been able to have an immune system to survive due that.
                                  Think of avant guard artifacts from the ancient history, the pyramids...

                                                            Why are modern humans not different species? I am asking from a purely scientific standpoint since physical and genetic differences are real and apparent (while they have no bearing on the kind of person you are) I don't understand why each group of humans doesn't get its own classification?

It should be looked at as a merging continuum instead of compartmentalized. Neanderthals didn't go "extinct." They were simply merged into the evolving modern human, and because the product was superior, Neanderthals faded away. I'm sure Homo heidelbergensis from around 500K years ago and Homo antecessor 1 mill. years ago will be proved as our descendants as well.

Phenotype follows genotype up until the point where interbreeding results in no viable offspring. Observe the cultures around you and think.

Would that not mean those offspring are a completely different species......
