96 fixed amino acid substitutions, not 96 genes

19 December, 2013 – 09:31 april holloway Entire Neanderthal genome finally mapped – with amazing results Excerpt (with my emphasis): “Only 96 genes responsible for making proteins in cells are different between modern humans and Neanderthals. Intriguingly, some of the gene differences involve ones involved in both immune responses and the development of brain cells in people.” “Somewhere within 96 fixed amino acid substitutions, not 96 genes

Social experiences epigenetically effect gene networks

Networks of Genes Respond to Social Experiences October 13, 2013, from Searching for the Mind with Jon Lieff, M.D. Excerpt 1: “The gene networks of social experience are consistent through many animals.” My comment: Not just many animals; the gene networks of social experiences must be consistent in all animals that adaptively evolved. You cannot Social experiences epigenetically effect gene networks

Evolution: innovations may have non-adaptive origins (sans mutations)

Q & A: Evolution Makes Do By Chris Palmer Evolutionary biologist Andreas Wagner argues that many evolutionary innovations may have non-adaptive origins. Excerpt: “If exaptations are pervasive, then natural selection—which few doubt is critical for the preservation and spreading of traits—may not be that important for the origin of innovations in life’s history.” See also: Evolution: innovations may have non-adaptive origins (sans mutations)

Are pheromones responsible for human body odour assessment?

Can You Smell Yourself? by Sarah C. P. Williams on 22 January 2013, 5:10 PM Excerpt: “Other molecules the human body produces could also influence individual smells and scent preferences, Zufall says. The individuality of people’s microbiomes—the collection of microbes living in and on us—could also be linked to the body’s odor or preferences, Wedekind Are pheromones responsible for human body odour assessment?

Evolved development of olfactory systems

how much longer it will be until the “bird watchers” realize that the molecular mechanisms of how olfactory/pheromonal input epigenetically effects adaptively evolved behaviors are the same in species from microbes to man, and species of birds are included.
