We need pattern recognition, not a prologue

Prolegomenon “a preliminary discussion…; a prologue.” “… we need a mapping from genotype to phenotype, from phenotype to what is selected, and from what is selected to the new genotype (Lewontin, 1961). — cited in Prolegomenon to patterns in evolution Excerpt:  “…we cannot derive what selection, acting at the level of the whole organism in its world, will “select” among the possible but unprestatable…” My comment: Organisms naturally select the nutrients that enable thermodynamic cycles of protein biosynthesis and degradation,…

From deep time into real time: What evolutionary processes?

Rapid evolution of a native species following invasion by a congener Abstract excerpt: “…the lizard Anolis carolinensis moved to higher perches following invasion by Anolis sagrei and, in response, adaptively evolved larger toepads after only 20 generations.” My comment: This indicates that the behavior evolved before the species, in response, evolved larger toepads. Reported as: Florida lizards evolve rapidly, within 15 years and 20 generations Karl Grammer’s comment: “Proofs for evolutionary processes…” What evolutionary processes? RNA-directed DNA methylation links the…

Genes and Race: Human History?

Roundup of Book Reviews of Nicholas Wade’s A Troublesome Inheritance My comment: Many reviewers of Wade’s book on genes and race appear to think he has accurately represented issues of differences in cell types that evolutionary theorists associate with mutations, natural selection, and the evolution of human biodiversity. This may be cause for concern among those who are interested in accurate representations of biologically-based cause and effect. In this century, it has become clear that ecological variation results in biodiversity, which…

Darwinian theories vs Darwin's facts

“Darwin’s Theories“, submitted by Celia Secades of the Elesapiens website was the runner-up in the Third Annual NESCent Evolution Video Contest. (unfortunately, the video has been removed — perhaps for good reasons. For example: My comment: No experimental evidence supports the representations of mutation-initiated natural selection in the video. For comparison, tenOever on microRNA and Vaccines  addresses what is currently known about glucose-dependent RNA-mediated amino acid substitutions and self vs non-self identification in viruses to living species with varying degrees of nutrient-dependent pheromone-controlled ecologically-adapted organismal complexity.…

Nutrient-dependent pheromone-controlled stickleback evolution

Sexual imprinting on ecologically divergent traits leads to sexual isolation in sticklebacks Excerpt: “Odour differences may be owing to pleiotropic effects of adaptive differences in diet [18], habitat [12] and major histocompatibility complex (MHC) alleles selected by parasite differences [19,20].” Excerpt: “…imprinting has turned odour and nuptial coloration into magic traits.” My comment: In my model, natural odour production in vertebrates is not a magic trait. It results from the role of food odours in nutrient-dependent RNA-mediated ecological niche construction.…
