Kohl (2013) Excerpt:
‘Members of the Society for Integrative and Comparative Biology (SICB) recently organized and held an ecological epigenetics symposium (January, 2013). Clearly, a new generation is familiar with the concept of ecologically driven epigenetic effects, which can be caused by sensory input that effects hormones, which affect behavior. To a lesser extent, a new generation may be familiar with the concept of human pheromones that effect hormones, which affect behavior. This review links the concept of human pheromones to a model for the epigenetic effects of pheromones on adaptive evolution via extension of ecological epigenetics to what is neuroscientifically known about ecological, social, neurogenic, and socio-cognitive niche construction.’
2014 Society for Integrative and Comparative Biology (SICB) meeting abstracts: https://sicb.org/meetings/2014/SICB2014AbstractBook.pdf
In the 385 pages of abstracts,
1) a search for “mutation” returns 30 entries
2) a search for “amino acid” returns 31 entries
3) a search for “natural selection” returns 18 entries
Although it is now perfectly clear that the holy grail of evolutionary biology is the nutrient-dependent pheromone-controlled de novo Creation of genes, the “no-brainer” approach to statistical analysis of the abstracts (skewed by more than one use of the term “mutation” or “amino acid” ) indicates great confusion among researchers who are involved in “Integrative and Comparative Biology.” Half may think that the theory of mutation-initiated natural selection will enable their integration of comparative biology. The other half may subconsciously realize the biological fact that nutrient-dependent amino acid substitutions link the epigenetic landscape to the physical landscape of DNA in all the cell types of all organisms of all species. However, it still seems largely unknown to the people presenting at this conference that the metabolism of nutrients to species-specific pheromones controls the physiology of reproduction in species from microbes to man.

Kohl (2013) Excerpt:
“Hormones are chemical messengers that transport signals between cells in multicellular organisms. Like other hormones, androgens organize and activate genetically predisposed vertebrate behavior.
The affects on mammalian behavior of androgen organization and activation were first reported by Phoenix, Goy, Gerall, and Young (1959). In the same year, a new class of biologically active substances was defined.
Pheromones are … substances which are secreted to the outside by an individual and received by a second individual of the same species, in which they release a specific reaction, for example, a definite behavior, or a developmental process. (Karlson & Luscher, 1959, p. 55).
Transport of chemical signals among organisms differentiates pheromones from hormones, which transport chemical signals within multicellular organisms. The definition of pheromones infers that they alter behavior by altering levels of hormones, which organize and activate developmental processes. In essence, pheromones are species-specific chemicals (e.g. social odors) that effect hormones, which cause behavioral affects.”
Fifty-five years after it became perfectly clear that nutrient-dependent pheromone-controlled ecological adaptation is responsible for hormone-organized and hormone-activated developmental differences in species, it seems there will be no end to the confusion about biologically based cause and effect that was introduced via the theory of mutation-initiated evolution.
As you can see via a quick search of the abstracts linked above, the theory of mutation-driven evolution continues to be reintroduced into reports of results from scientists who may never ask themselves or their professors: How can mutations possibly result in natural selection and ecological adaptation?
On the SICB FB page, I’ve asked the question twice in the past two days: Is anyone willing to take a public stand on whether or not ecological variation is the only driving force behind species diversity?
Others should feel free to answer that question in comments on this post.
