Document Summary

Adaptation: a trait that allows its bearer to survive and reproduce better than competing individuals that lack the trait. Fitness: a (cid:373)easu(cid:396)e of a(cid:374) i(cid:374)di(cid:448)idual"s (cid:396)elati(cid:448)e success in propagating its genes into the next generation by the production of kin that survive to reproduce. Inclusive fitness: a measure of an individuals success in propagating its genes into the next generation via the production of descendent and non-descent kin that survive to reproduce. How these relate to the examples of cooperative courtship in turkeys and fruit flies: Related males work in pairs to attract mates. The subordinate male increases the reproductive success of the dominant male by chasing away competitors so the dominant male is able to continue displaying his courtship behaviour. This indirectly benefits the subordinate male because they have more inclusive fitness helping the dominant male than they would on their own.
