Short Wave Antenna

short wave antenna

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 flies 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 with 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 adpted for other uses.
c. Variation in leg-waving may have been present in acnestral populations and availabe for natural selection, while variation in antennae length may not have.
d. GIven enough time, these flies will develop longer antennae and become perfect mimics.
e. Organisms are often locked into historic genetic constraints.

c. Variation in leg-waving may have been present in acnestral populations and availabe for natural selection, while variation in antennae length may not have.

Most organisms are not perfect in their environment and if they were why would evolution exist? The flies ancestors “spread” a beneficial mutation through natural selection. While longer antennae might also have thrived through natural selection, the mutation never occured, but may still in time to come.
