blackbootz:

So the insight is that some adaptations (like the rove beetle’s body shape and glands) might be predisposed to genetic mutation, enabling multiple lineages of rove beetles to mimic unique ant characteristics like shape and smell from different colonies. And the word for this is “preadaptation.” I’m curious how some parts of the genome are more predisposed to mutation. Isn’t allele switching during fertilization a random process? Or do some parts of chromosomes “mix” more than others? I assume rove beetles are a sexually reproducing species.
