Excerpt 1): “In studies attempting to determine the molecular basis for beak variability in finches, researchers have found that very similar developmental genetic pathways among species can produce markedly different beak shapes.5 ”
My comment: More than 12 of my blog posts have included information about how the epigenetic landscape becomes the physical landscape of DNA in species from microbes to man via conserved molecular mechanisms.
Excerpt 2): It’s becoming evident that both genetic variability and epigenetic mechanisms are built into the genome as adaptive systems of variation that allow for robust speciation to occur within the boundaries of created kinds. However, these processes never allow for amoeba-to-man vertical evolution.
My comment: The nutrient-dependent amino acid substitutions that stabilize the organized genomes of species from microbes to man attest to the fact that ecological variation leads to ecological adaptations via conserved molecular mechanisms, not via mutations, natural selection, and evolution.
Consider the clarity of this statement: “We cannot conceive of a global external factor that could cause, during this time, parallel evolution of amino acid compositions of proteins in 15 diverse taxa that represent all three domains of life and span a wide range of lifestyles and environments. Thus, currently, the most plausible hypothesis is that we are observing a universal, intrinsic trend that emerged before the last universal common ancestor of all extant organisms.”
Anyone who wants to answer the question “What about birds?” must now frame their answer in the context of what is known about biology. No evolutionary events have ever been described. What’s known links ecological variation to ecological adaptations in birds and all other organisms via nutrient-dependent pheromone-controlled cell type differentiation, which enables ecological speciation.
