a. true
b. false
Ans: a. true
(E. eschscholtzii and E. xanthoptica should have more similar genes because they interbreed directly rather than indirectly.)

If the complex protein assemblage of the prokaryotic flagellum arose by the same general processes as those of the complex eyes of molluscs (such as squids and octopi), then _____
A) natural selection cannot account for the rise of the prokaryotic flagellum B) ancestral versions of this protein assemblage were either less functional or had different functions than modern prokaryotic flagella C) neither eyes nor flagella could have arisen by evolution because both are too complex to have evolved D) the need for more complex structure must have driven evolution
