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.
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
