Females chose males based on their genetic quality (Anderson 1994).
Secondary Sex Traits:
are sensory displays that raise the success of the possessor in competition over
mates (Anderson 1994).
The Thesis Project:
is a good-genes theory test that focuses on wing-song.
Traits are favored because they already fit an existing sensory bias in females
Females evolve resistance to courtship due to male induced harm
(Holland and Rice 98).
There will not be a significant difference in the rate of evolving thermal tolerance between the populations.
