“[T]he pfhrp2 deletions had arisen recently and hadn’t had time for mutation and
recombination to scramble the DNA sequences nearby. So,
all the [malaria] parasites that carry the pfhrp2 deletion seemed to have

was a selective pressure that was driving the expansion of parasites that
inherited the deletion.”

“[O]ctopuses can alter the coloration of their skin, with darker colors
typically being indicative of aggression. The authors found that octopuses with
dark coloration threw debris more forcefully and were more likely to hit another
octopus.”
