Fill in the blank(s) with the appropriate word(s).
In certain motile prokaryotes, dozens of different proteins comprise the motor that powers the prokaryotic flagellum. The motor has a complicated structure, and its various proteins interact to carry out its function. Based on Darwin's explanation for the existence of human eyes, how would he probably have explained the existence of such motors?
A) Because he could not have explained their existence, he would have used supernatural agents as a temporary explanation until the gap in scientific knowledge had been filled. B) Because he could not have explained their existence, he would have concluded that the human brain has not (and probably cannot) evolve the capability to solve such complex problems. C) He would have proposed that these motors were the products of aliens, and had been delivered to Earth by extraterrestrial visitors. D) Faced with such complexity, he would have given up science. E) He would have proposed that less complicated, but still functional, versions (though maybe with a different function) had existed in ancestral prokaryotes.
