* The Past
* Cryptic Populations
* Sideways in Time
* The Future
* Science!
It left out crossbreeding with other species (like Spock in Star Trek) as well as backbreeding where remnant genes become more prevalent due to environmental pressures until speciation occurs. Regarding the latter, Sherpas are already a borderline species because they can survive at higher altitudes than other Homo sapiens due to their Denisovan heritage. They are at least a definable subspecies based on habitat adaptations, more realistically a remnant population of Denisovans with heavy Homo sapiens introgression. But when you start talking about biological differences among humans, then humans immediately start doing stupid things, so most scientists won't do it. Anyhow, if the Sherpas became isolated from other humans and stayed in the Himalayas, environmental pressure would push them toward more Denisovan-like traits.
