#Question id: 4994

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 Darwinʹs explanation for the existence of human eyes, how would he probably have explained the existence of such motors?

#Unit 11. Evolution and Behavior

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.
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.
He would have proposed that these motors were the products of aliens, and had been delivered to Earth by extraterrestrial visitors.
He would have proposed that less complicated, but still functional, versions (maybe even with a different function) had existed in ancestral prokaryotes.
