I mean, there was a selectivity to it, yes. But also a whole lot of random chance, which is why it kept happening instead of fixing itself in a few generations.

It's still how it works. We're either going to artificially fix the problems or go back to that, and do so in an evolutionary eye blink - almost certainly in our lifetimes, by the look of it.

Also wrong. WTAF this thread. Lemmy just loves to make up science.
