Natural selection: New insights are unlikely
Excerpt: “Recent studies suggest that natural selection described by Charles Darwin also occurs at the cellular level.”
My comment: How else could natural selection occur if not at the cellular level? Who’s claiming this has anything to do with new insights? See for example Human pheromones and food odors: epigenetic influences on the socioaffective nature of evolved behaviors where I conclude that: “Olfaction and odor receptors provide a clear evolutionary trail that can be followed from unicellular organisms to insects to humans.”
If natural selection did not occur at the cellular level the conceptulization of epigenetic tweaking of immense gene networks in superorganisms that solve problems through the exchange and the selective cancellation and modification of signals would not have been possible. Natural selection occurs at the cellular level because cells select for nutrients that enable their survival and the nutrient chemicals metabolize to pheromones that control reproduction, which controls species survival and nutrient chemical dependent species diversity.
