>Considering we only differ from chimps by about 4% in genome
from what I understand, while human males differ from male chimps by about 1% in genome*, that still means that human males are more closely related to male chimps than they are to human females.

How do you compare the similarity of books? Letter counts? Word counts? Is Romeo & Juliet more similar to Captain Underpants than its own translation into Italian?
- nine_k 2y agoNo, it's like comparing editions of basically the same book ("Hominid"), with some paragraphs using slightly different wording, a phrase added or removed here and there, old typos fixed, new typos added, etc. It's still largely the same book, but the tone is different in some key places, and the finale leaves a very different impression as a result.

- lumpa 2y agoHomo sapiens are apes and are also virtually identical in physiology compared to other apes if the external comparison group is dogs or cats.
- JumpCrisscross 2y ago> still largely the same book What is your metric? The point is our measures of genetic “distance” aren’t precise enough to make statements like OP’s. At least half of it is eukaryotic operating code, and much of the remaining is “junk” DNA we’re only beginning to understand

- dyauspitr 2y agoImagine running a diff but with nucleotides.
- kgeist 2y agoI thought geneticists already do that?
- JumpCrisscross 2y ago> Imagine running a diff but with nucleotides That's my point. Two different books of similar length in the same language will probably diff more closely than the same book translated. (Even if we limit ourselves to the same character set.) That says nothing about the content, just the encoding.
- dyauspitr 2y agoThe analogy breaks down because there’s really only one language when it comes to interpreting nucleotide sequences.
- not2b 2y agoHow could that be? The only genetic difference is the presence of the Y chromosome. If it were the same size as all the others, it would be a 1/46 difference, so about 2%. But it is smaller than all the others, so maybe 1% or even less difference . The other 45 chromosomes are the same for men and women.
- dyauspitr 2y ago2.2% > 1%
- bonzini 2y agoThe point is that females have 46 full chromosomes and males don't. If you take into account that one of the 46 is essentially inactivated in females, that's obviously another story; but as far as nucleotides go, the genetic difference between male and female humans is 1/46th.
