«I think it's remarkable to find industrial melanism in organisms as different as moths and seasnakes!»

He gives only one example of evolution of any kind, a change in gene frequencies in a locus controlling melanism in the peppered - moth Biston betularia, and argues that this is «the most famous piece of evidence for Darwinism» and that «examples of this kind allow Darwinists to assert as beyond question that «evolution is a fact.

If so, does this contribute to the link between behavioral and physiological traits and melanism observed in adult owls?

These findings raise the intriguing possibility that sleep - related developmental processes in the brain contribute to the link between melanism and other traits observed in adult barn owls and other animals.

The industrial melanism mutation in British peppered moths is a transposable element.

Darwin knew nothing of Mendelian heredity of industrial melanism, but be had three very powerful arguments and sets of evidence for evolution sufficient to convince himself and, by the end of his life, a great number of others who were initially skeptical.

Yet Johnson totally ignores all this evidence for evolution, arguing instead that he has adequately covered the evidence by mentioning and ridiculing the case of industrial melanism.

For instance, one admits that in much of evolution (probably all above the bacteria), evolutionary changes involve enormous numbers of genes, rather than a selection of one or two particular genes (although that occurs in a few instances, possibly, for instance, in industrial melanism).

Polluted waters may be driving more sea snakes to go all black, a sign of an evolutionary phenomenon called industrial melanism, Susan Milius reported in «Polluted reefs may favor dark snakes» (SN: 9/16/17, p. 14).

The process is known as industrial melanism — melanism meaning the development of dark coloured pigmentation.

Indeed, the team found that owlets expressing higher levels of the gene involved in melanism had less REM sleep than expected for their age, suggesting that their brains were developing faster than in owlets expressing lower levels of this gene.

The findings add seasnakes to a growing list of species that show industrial melanism, a greater prevalence of dark - colored varieties in industrial areas.
