Explanatory duality: Science in flies is not Nature in butterflies

Evolutionary Duality

When ecological divergence involves traits that also contribute to mating behavior, such divergence could lead to rapid reproductive isolation and speciation. However, there are very few experimental demonstrations of such “dual” traits. Chung et al. (p. 1148, published online 13 February) now demonstrate that specific cuticular hydrocarbons are a dual trait that affects both desiccation resistance and mate choice in the widely distributed Australian species Drosophila serrata. These compounds have largely been lost from its rainforest-restricted, desiccation-sensitive, closely related sibling D. birchii.

My comment: Fatty acid metabolism and pheromone production link a single gene to ecological adaptations and species diversity in flies.

My comment to Science magazine was submitted on 3/7/14 and approved and posted on 3/10/14

Ecological variation and adaptations associated with a single gene and with nutrient-dependent pheromone-controlled mate choice in flies became meaningful mutations in the regulatory sequences of a single gene in butterflies associated with mimicry.

Evolutionary biology: Sex, lies and butterflies

Has anyone seen experimental evidence that suggests that the molecular mechanisms that enable species diversity are different in flies and butterflies?

About James V. Kohl 1308 Articles
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. Recently, Kohl integrated scientific evidence that pinpoints the evolved neurophysiological mechanism that links olfactory/pheromonal input to genes in hormone-secreting cells of tissue in a specific area of the brain that is primarily involved in the sensory integration of olfactory and visual input, and in the development of human sexual preferences. His award-winning 2007 article/book chapter on multisensory integration: The Mind’s Eyes: Human pheromones, neuroscience, and male sexual preferences followed an award winning 2001 publication: Human pheromones: integrating neuroendocrinology and ethology, which was coauthored by disinguished researchers from Vienna. Rarely do researchers win awards in multiple disciplines, but Kohl’s 2001 award was for neuroscience, and his 2007 “Reiss Theory” award was for social science. Kohl has worked as a medical laboratory scientist since 1974, and he has devoted more than twenty-five years to researching the relationship between the sense of smell and the development of human sexual preferences. Unlike many researchers who work with non-human subjects, medical laboratory scientists use the latest technology from many scientific disciplines to perform a variety of specialized diagnostic medical testing on people.
