Reply to comment by Ferociousfeind in When it's said 99.9% of human DNA is the same in all humans, is this referring to only coding DNA or both coding and non-coding DNA combined? by PeanutSalsa

Is it remarkable though? I would imagine most species' DNA is unremarkably similar to the same species DNA? Are humans more remarkable?

Yes, we are compared to other animals, and the reason we think this is because tens of thousands of years ago there was a super volcano eruption that made our population around 10,000 or less. So we are not as genetically diverse as other animals are

What?... So we would have been even more genetically diverse huh.

Why did this event not also constrict other species?

Because they had time to diverge before it, and our divergence came after it?

It did affect certain animals of course, but we were ran to near extinction. But most of the animals we see today don’t seem like there genetic diversity was affected that much. And yeah, most likely they diverged way before that, even before the super volcano we have had times where we have had extremely low population.

From what I've read, other species have generally much higher variance.
