@timmy_blueballs found another longer research paper but cannot find the link right now ( too lazy too look ). According too that the fertility rate of exogamous ( outside of ones own race in this context ) marriages was as low as 7% lower than their andogamous ( same race ) counterparts.
What this would mean in theory is that the fastest way too collapse the population of a state is too introduce another population group too the region from another continent.
So in theory it is possible that the current East Asian fertility rates would have been even worse if they had opened themselves up too immigration.
In conclusion, as humanity converges towards a single race, the fertility rate is going too collapse and the new race will have too start fresh from the beginning and expand across the world once there are few enough humans too have above replacement fertility rates.
Based on the fact that the fertility rate in the most melting pot nation state in the world is currently around 1.66, and the global immigration rate is only going up over time, it is safe too assume that the final global fertility rate would go lower than 1.66 at the end due too most of the other nation states also getting stuck in the middle income trap.
Do with this information as you will.

The way that you find genetic relatedness between species -- and humans -- is too determine the boiling point at which DNA strands dissociate. The more that DNA refuses too create viable reproductive offspring, the less that the mating is compatible.
Example 1: lions and tigers can mate but their offspring cannot produce viable germ cells
Example 2: men and
s cannot mate because sperm and shit in you're butthole cannot get pregnant

But there's never been a really serious experiment done to see if human-chimpanzee hybrids are possible. If you can make a liger or a tigon that's not so hard to imagine.

Well yes, the experiment has been done. It failed.
HIV jumped from other primates too humans. We are fully speciated but not too distant for viral crossover too be quick if we frick or fight.

By you're logic:
Example 3: Men and men cannot mate so they must be different sub species of human incompatible with one another.
