Although some male crab spiders find and mate with adult female spiders, others that find immature females remain with them although the sub adult females are incapable of mating until they become adults. This behavior would puzzle most evolutionary biologists because: a. The genetic basis for this behavior would be very difficult to determine. b. Mating is instinctive in spiders and therefore all males should behave the same, either mating with adult females only or guarding sub adult females only. c. Males that guard sub adults cannot use the time to find receptive females. d. One would think that immature female spiders should accept and store sperm from males in order to permit good female-finding males to have time to find many mates.

1. Although some male crab spiders find and mate with adult female spiders, others that find
immature females remain with them although the sub adult females are incapable of mating until
they become adults. This behavior would puzzle most evolutionary biologists because: a. The
genetic basis for this behavior would be very difficult to determine. b. Mating is instinctive in
spiders and therefore all males should behave the same, either mating with adult females only or
guarding sub adult females only. c. Males that guard sub adults cannot use the time to find
receptive females. d. One would think that immature female spiders should accept and store
sperm from males in order to permit good female-finding males to have time to find many mates.
Solution
The answer to this concept is ans (4)..one the female immature spider should store the sperms in
them for good female - findings males to have time to find many other..
