Criticism of the theory of Natural Selection

The great scientist Pierre Paul Grasse writes,

“The role assigned to natural selection in establishing adaptation, while speciously probable, is based on not one single sure datum. Paleontology (cf. the case of the transformation of the mandibular skeleton of the theriodont reptiles) does not support it; direct observation here and now of the genesis of a hereditary adaptation is nonexistent, except, as we have stated, in the case of bacteria and insects preadapted to resist viruses or drugs. The formation of the eye, the inner ear, of cestodes and the whale, etc., does not seem possible by way of preadaptation. Besides, paleontology teaches that the evolution of the stirrup bones of the inner ear took place exceedingly slowly by the unambiguous addition of tiny changes, preadaptation had nothing whatever to do with it.

The role of natural selection in the present world of living things is concerned with the balance of populations; it is primarily of demographic interest. To assert that population dynamics gives a picture of evolution in action is an unfounded opinion, or rather a postulate, that relies on not a single proved fact showing that transformations in the two kingdoms have been essentially linked to changes in the balance of genes in a population. Circumstances occasionally award a given mutation a selectivity bonus, but for a variable time, as witness the heterogeneity of populations due to the abundance of alleles of a single gene and their composition over time. Studies on natural populations in their own proper environment show that the composition of genes is changeable and that dominant species vary over time. Ford (1971), in his book, says precisely this and nothing else; as for seeking.” (Evolution of Living Organisms, p. 170)
