Given the bottleneck in the human population in the last 70,000~ years, it's borderline ludicrous that humanity would be the most genetically diverse species in the galaxy. Humans are one of the least genetically diverse species on Earth, but they're somehow more diverse than the rest of the galaxy? That plot point has always bothered me.
Where do you figure any of this from? What bottleneck would that be? Look around, there are hundreds of different ethnicities that each possess traits unique from one another whether it be skin color, facial structure, body size and build, mucle density, etc. Not to mention that our males are inherently different from females. Just look at asari in-game for an example of a general lack of genetic diversity, they don't even have male/female genetics.
It is surmised from the Toba eruption, which most geneticists believe reduced the numbers of humanity to ~10,000 (and perhaps left as few as 1,000 viable breeding pairs). Our physical appearance is irrelevant in terms of genetic makeup. You will find less genetic variation between an Asian and European than you would between two chimpanzee groups in Africa. At any rate, I understand that it can be plot magicked for sake of the story, but one of the things I enjoyed about the earlier parts of the series was that humanity wasn't special. And, through this, it was. It's a tired sci-fi trope, was disappointing is all.
Side note: Some believe the bottleneck occured 50,000 years ago. Dun dun dun!
