What worm has natural selection selected AGAINST? _________________ FOR? ________________?
There are 2 types of worms: worms that eat at night (nocturnal) and worms that eat during the day (diurnal). The birds eat during the day
and seem to be eating ONLY the diurnal worms. The nocturnal worms are in their burrows during this time. Each spring when the worms reproduce, they have about 500 babies but only 100 of these 500 ever
become old enough to reproduce.

Is that the whole question? Looks like they are saying natural selection has selected against the diurnal worms (because there is a natural predator), and FOR the nocturnal worms.
