I disagree mostly on priors, since it's quite unlikely that we discovered, understood, and pinpointed the biggest source. Would agree with a slightly weaker version of this claim.
If evolution were optimizing creatures that were exactly like humans except that they were not social at all (maybe they each have their own planet), then almost all of the biases would disappear.

Does "better" include "more like the in-group"? If yes, this seems very plausible. If no, I'd guess the crony beliefs cluster is a bigger source.
Better in a locally zero-sum way has some direct checks (because the people you're interacting with you have an incentive to see if you're deceiving them about your usefulness), whereas locally positive-sum biases (e.g. "my in group is the best in-group, and is right about everything") should be selected for.
I want a clarification on the claim. How should this be handled, should it be attached to the claim? Decided by the author? Just left in the comments?
Probably not high priority. Comments seems okay.
I think it is important. I now want to refine the claim.
Perhaps make it a new replacement claim, and notify everyone who marked this claim that it's been replaced? I don't want people to be able to edit claims to make it appear I have a credence for a statement, and I don't want my credence wiped whenever a claim is edited.
