I have read about hybrid speciation: "speciation where hybridization between two different species leads to a new species, reproductively isolated from the parent species". I wanted to know if it would be possible for two members of the homo genus to come together, create a hybrid species, and having that species/subspecies reproduce isolated from the parent species, given these parameters for a potential story:
- A Homo sapiens and other member of the Homo genus (like a Neanderthal) come together to produce and child. Other members of both human species follow suit.
- The union leads to hybrids that can be considered a new species/subspecies of the Homo genus. These hybrids separate and reproduce
- The hybrids continue to live on a produce more of their new species. This species continues to exists as Neanderthals die out and competes directly with homo sapiens, forming their own society that continues into this alternate-worlds version of the modern day
