how can Homo sapiens and Neanderthal be different species but Neanderthal dna is common in modern day people

861 views

To my 5 year old knowledge I thought Neanderthals were different species but for us to have part of their dna that means they got jiggy together and created fertile off spring with Homo sapiens but when a donkey and a horse do it they make infertile offspring? Are we not like actual separate species?

Just like dogs are all members of the same species and yet the multiple breeds can procreate and create viable offspring. Neanderthal extinction would be the equivalent of specific breed’s extinction.

Homo(sapien)
Homo(neanderthalensis)

Homo would be the genus which we share with them and others allowing us to mate with viable offspring being the product.
