First, selection can act only on existing variations. Eventually, the individuals with the favorable traits have a higher rate of reproduction and survival. In a nutshell, he argued that an “appreciable fraction” of the genetic variation within and between species is the result of genetic drift — that is, the effects of randomness in a finite population — rather than natural selection, and that The engineer Theo Jansen read the book in 1986 and became fascinated by evolution and natural selection.
