You have been studying a newly discovered species of lemur. You have established that sexual selection has been a powerful force in the evolution of this species and it is clear that female choice plays an important role in determining which males procure mates. After many hours of observation and data collection, you find that females prefer males that are more proficient at collecting sap and fruit. You should conclude that your data strongly supports the good genes hypothesis.
Answer the following statement true (T) or false (F)
True
Your data does support the good genes hypothesis which suggests that females choose mates on the basis of traits that improve the chance of survival rather than on appearance.
