I'm not a scientist, but as far as I can tell... do that?

Half the interest in archeological type studies seems to be "ok, this the earliest history we know of, what came before that?"

I agree that humans tend to get way too entitled about (maybe) sharing genes with someone who did something cool in past history, but learning about which populations migrated to egypt and from where and when, seems unrelated.
