How would self-sacrifice of male redback spiders be an adaptive behaviour?
A) Males only use self-sacrificing behaviour once they have mated with several females and have exhausted their sperm supplies.
B) The chance of a male meeting more than one female is quite low; self-sacrifice maximizes mating time with and sperm transfer to any female the male finds.
C) Males are able to mate with one female, then mate with another female nearby, before being devoured by the first female.
D) When males meet a female and self-sacrifice, it activates enzymes that make his sperm more fit and able to fertilize more eggs.
