Query: genetic mistakes = very intelligent design ?

In regard to these "inspired intelligent robots" one has towonder if there is compelling empirical evidence for the origin of the tiny motors driving biological processes at the cellular level. In other words, has there ever been a series of genetic mistakes that have been traced out, mapped out or otherwise hypothesized showing how these motors came from nonmotors?Johnson & O'Donnell said the sliding clamps & clamp loaders involved with DNA replication have "evolved clever strategies to perform their function" (Annual Rev. of Biochemistry, 2005, p. 283), but is this not a veiled tautology?
