)a third population of crayfish lives in a very muddy stream. like the cave form, these crayfish have longer antennae, but unlike the cave form, these muddy stream-dwelling crayfish have retained their eyes. of the following hypotheses, which best explains how crayfish in the muddy stream have long antennae? a. among crayfish in the muddy stream, those with sense1 had greater reproductive success than those without sense1. b. in many crayfish individuals in the muddy stream, a mutation occurred that increased the length of antennae, but did not increase the activity of sense1. c. crayfish in the muddy stream are more closely related to the cave crayfish than they are to the surface crayfish. d. among crayfish in the muddy stream, those that possessed a mutation that increased the length of antennae, but not the activity of sense1, had greater reproductive success.
