Devon Stack just did a great stream on the topic of race, where he debunks the usual types who try to downplay our very real genetic differences. Turns out small percentages in DNA can have a huge impact.

Just because two animals share a greater percentage of DNA, it doesn't necessarily mean they are more similar to each other, than animals that have less DNA in common.
Any two fruit flies can be as genetically different from each other as a human is from a chimpanzee.
Animals that have gone through genetic bottlenecks, like humans and cheetahs, end up with individuals who are genetically closer to each other. However, those different genes can be far more potent and apparent than in other species.
In a single group of penguins, individuals can have 2x the amount of genetic difference than humans have, yet they all look/behave the same.
On the other hand, different cheetah SUBSPECIES have 2x more DNA in common with each other than Whites have with Blacks.
@Zeb Good example. Like with computer code, a lot of it can be redundant or even broken. Just having more data, doesn't say anything about its usefulness. Efficient, small changes can be far more important than big differences in size.
Don't forget spiders.
They share most of the DNA yet the smallest different DNA create an entire new subspecies that might behave, hunt and even reproduce completely different than other spiders.
Their level of specialization with the smallest DNA change and adaptability to any environment are very impressive.
