________________ 266 Jaina Biology selection is involved in the survival of some, according to Darwin, but not all, of the mutations which occur."47 According to modern Biology, (1) "Evolution occurs more rapidly at some times than at others. At the present time it is occurring rapidly, with many new forms appearing and many old ones be coming extinct. (2) Evolution does not proceed at the same rate among different types of organisms. In general, evolution occurs rapidly when a new species first appears, and then gradually slows down as the group becomes established. New species do not evolve from the most advanced and specialized forms already living, but from relatively simple, unspecialized forms. (4) Evolution is not always from the simple to the complex. There are many examples of “regressive" - evolution, in which a complex form has given rise to simpler ones. (5) Evolution occurs by populations, not by individuals by the processes of mutation, natural selection and genetic drift" 48 47. Biology, p. 523. 48. Ibid. p.523.
