AP Biology question chapter 23?

[caseyliz]

Female wasps, which are protected by the use of a painful stinger, often make their presence conspicuous by rapidly moving their usually long antennae. These wasps are often mimicked by fliew with short antennae who give the appearance of rapidly moving long antennae by waving their forelegs in front of their bodies. Which of the following statements concerning this behavior is NOT consistent w/ current evolutionary theory?

a. natural selection cannot fashion perfect organisms
b. the behavior of the flies may be a compromise if their short antennae are adapted for other uses
c. variation in leg-waving behavior may have been present in ancestral populations and available for natural selection, while variation in antennal length may not have.
d. given enough time, these flies will develop longer antennae and become perfect mimics
e. organisms are often locked into historical genetic constraints
