Paley takes his argument against the role of chance a step farther, in the process raising—and summarily rejecting—a possible explanation that exhibits shades of the principle of natural selection. However, his description is of an ancient version of the idea that, as Paley rightly notes, is unworkable in practice. Footnote 12Jun 4, 2019 · Functionality. The trait must have a function. Traits must do something for natural selection to take place. Advantage. To be selected for passing on to descendants, the trait must confer an advantage on the organism that has it, or make the organism more fit for survival in its environment. Origin.

If the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change). Mechanisms of evolution correspond to violations of different Hardy-Weinberg assumptions. They are: mutation, non-random mating, gene flow, finite population size (genetic drift), and natural selection.

It is on the latter that the principle of Natural Selection relies. Fisher (1930, p. 37) In 1954 Fisher contributed to Evolution as a Process, edited by Julian Huxley, A. C. Hardy, and E. B.

Briefly explain how each of these principles is necessary for natural selection to occur. Variation = natural variation in genetic code, due to mutations. Without this, change would never occur. Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).
