What about birds (2)

August 18, 2013 | James Kohl

In this 11 minute-long video misrepresentation of how evolution occurs, mutations appear to be responsible for changes in the beaks of finches. In reality, the changes are nutrient-dependent and pheromone-controlled.

Nutrient-dependent:  Insights into the evolution of Darwin’s finches from comparative analysis of the Geospiza magnirostris genome sequence.

Excerpt: “21 otherwise highly conserved genes were identified that each show evidence for positive selection on amino acid changes in the Darwin’s finch lineage.”

Pheromone-controlled: Forget Plumage, Birds Sniff Out Good Mates

Excerpt: “Good “father” birds tended to have a more malelike odor.”

More across species examples of nutrient-dependent pheromone-controlled non-random adaptive evolution can be found in Nutrient-dependent/pheromone-controlled adaptive evolution: a model, which was published on June 14, 2013 in Socioaffective Neuroscience & Psychology

James Vaughn Kohl was the first to accurately conceptualize human pheromones, and began presenting his findings to the scientific community in 1992. He continues to present to, and publish for, diverse scientific and lay audiences, while constantly monitoring the scientific presses for new information that is relevant to the development of his initial and ongoing conceptualization of human pheromones.
