Question

A feature that reduces the fitness of an individual but benefits the population or species ________.

a. cannot evolve by individual selection
b. can evolve by group selection
c. will decline in frequency among other nonaltruistic phenotypes
d. All of the above e. None of the above

Answer 1

ANSWER: (D) ALL OF THE ABOVE

EXPLANATION: Based on the principle of natural selection theorized by Charles Darwin, a feature that reduces the fitness of an individual but benefits the population or species cannot evolve by individual selection for specific phenotype in reproduction of offspring to the next generation, rather by a group selection and will subsequently decrease in frequency in nonaltruistic phenotype (due to decrease in their inclusive fitness).
