Anatomical homology in vertebrate forelimbs is considered to be evidence for evolution because: 1. differences among vertebrate forelimbs suggest that they evolved independently. 2. the anatomy of the vertebrate forelimb is not currently under natural selection. 3. similarities among vertebrate forelimbs suggest that they evolved from a common ancestor. 4. such homologies do not exist in other areas of the vertebrate skeleton. 5. similarities among vertebrate forelimbs suggest that they have evolved convergently

Joe is breeding cockroaches in his dorm room. he finds that the average wing length in his population of cockroaches is 4 cm. he chooses the six cockroaches that have the largest wings; the average wing length among these selected cockroaches is 10 cm. joe interbreeds these selected cockroaches. from earlier studies, he knows that the narrow-sense heritability for wing length in his population of cockroaches is 0.6. a. calculate the selection differential and expected response to selection for wing length in these cockroaches. b. what should be the average wing length of the progeny of the selected cockroaches?
