Prehistoric genomes reveal the genetic foundation and cost of horse domestication Reported as: Reshaping the horse through millennia Excerpt: “Domestication is generally associated with repeated demographic crashes. Yet, mutations that negatively impact genes are not eliminated by selection and can even…

There’s a model for that!

social interaction and brain

Neuroscientists reveal mechanism crucial to molding male brains Excerpt 1) “…sex differences in brain function are established during the later stages of foetal development and around birth, but the actual cellular mechanisms underlying these important actions remained unknown.” My comment:…

Physics, Chemistry, and Molecular biology (PCMb)

human-evolution

Physics, Chemistry, and Molecular biology (PCMb) link ecological variation to ecological adaptations via a model of gene-cell-tissue-organ-organ system complexity that I first presented in 1992. After adding gene activation by pheromones, I co-authored a book that linked the pheromone-controlled physiology…

  Is Evolution Predictable? Excerpt:  “…evolution is not really predictable because too many chance events can knock it off course.” My comment: Ecological variation predicts nutrient-dependent pheromone-controlled ecological, social, neurogenic, and socio-cognitive niche construction via conserved molecular mechanisms manifested in the…

Gut microbes and integrative neuroscience

Physics

Diverse Microbes in Hunter-Gatherers’ Guts Modern hunter-gatherers have more diverse microbiota in their guts than do urban Europeans, but lack a few notable species. By Kerry Grens | April 16, 2014 Excerpt: Genetic diversity, rather than particular species, might be a more…

MiRNAs methylation and ecological adaptation sans mutations

human-evolution

MiRNAs methylation and ecological adaptation sans mutations  “Our 2003 Molecular and Cellular Biology paper …opened the mechanistic ‘black box’ of the developmental origins of adult disease susceptibility, and firmly placed the word, epigenetics, in the vernacular of this research field.”  — Randy…
