Olfaction and pheromones in birds
September 3, 2013 | James Kohl
Article excerpt: “In this study, an individual’s odour during the early season was correlated with reproductive success in that year, but visual cues such as size and plumage were less reliable predictors.”
My comment: Evolutionary theorists and especially human ethologists who have for decades touted mutation-driven evolution along with theories about how visual primacy in avian species can be used to predict visual primacy in humans have just been dealt another fatal blow to their ridiculous theories. Why won’t their ridiculous theories die?
Article excerpt: These observed correlations are likely caused by underlying, unmeasured factors such as hormone levels, condition and genotype.
My comment: If the epigenetic effects of nutrients and their metabolism to pheromones is the cause of the observed correlates, the evolution of birds (sans mutations theory) is already included in my model of nutrient-dependent pheromone-controlled adaptive evolution in species from microbes to man.
