When the Neanderthals Disappeared
Analysis of 40 European archaeological sites suggests a gradual extinction of Neanderthals over thousands of years.

Excerpt: “…new sample prep methods that include the filtering of collagen and isolation of a single mammalian-specific amino acid from bone—both of which allow for more accurate radiocarbon dating.”
My comment: More accurate dating links available information about how nutrient-dependent amino acid substitutions differentiate all cell types of all individuals of all species via conserved molecular mechanisms (examples in: Nutrient-dependent/pheromone-controlled adaptive evolution: a model.)
Conserved molecular mechanisms link the epigenetic landscape to the physical landscape of DNA in organized genomes of all species.
Dobzhansky (1964) seemed to be vaguely aware of that fact, which was briefly noted as: “Ingram and others found that hemoglobin S differs from A in the substitution of just a single amino acid, valine in place of glutamic acid in the beta chain of the hemoglobin molecule.”
Dobzhansky (1973) linked that fact to cell type differentiation in primates: “…the so-called alpha chains of hemoglobin have identical sequences of amino acids in man and the chimpanzee, but they differ in a single amino acid (out of 141) in the gorilla.”
What we now see is more evidence of nutrient-dependent pheromone-controlled cell type differentiation that can be placed into the context of what molecular biologists know about ecological variation and ecological adaptations. Thus, we can forget what population geneticists have been telling us during the past 50 years.
For example, see Starvation-Induced Transgenerational Inheritance of Small RNAs in C. elegans. It links nutrient-dependent amino acid substitutions in my model from ecological variation to ecological adaptations manifested in the morphological and behavioral diverstity of species from microbes to man via the physiology of reproduction in nematodes.
Ralf Sommer had this to say about that: “The patterns of synaptic connections perfectly mirror the fundamental differences in the feeding behaviours of P. pacificus and C. elegans” He attested to the fact that ecological variation leads to ecological adaptations manifested in teeth and the nutrient-dependent pheromone-controlled predatory behavior of nematodes with teeth.
The problem remains for population geneticists to provide any experimental evidence whatsoever that mutation-initiated natural selection leads to the evolution of biodiversity, which is manifested in nutrient-dependent pheromone-controlled cell type differentiation by amino acid substitutions and in the behavior of nematodes and modern human populations.
The question is how long it will be until serious scientists report on the pseudoscientific nonsense of evolutionary theorists that led many people to believe modern human populations evolved from primate ancestors over millions of years, but made the Neandertal to modern human transition in ~ 30,000 years by inbreeding, genocide, or anything else except nutrient-dependent pheromone-controlled ecological adaptations, like those manifested in the morphology of pygmies (in ~8000 years).
