All About Genes
by Steven Gussman Despite all of the posturing about, “interactionist,” models of phenotype (to say nothing of pure, “environmentalis,”) all of the theories of biology (and much of the controversial hypotheses still being argued over) are integrally genetic. You wouldn't know it from most discussions of behavioral genetics, but there are indeed reports of, “vacuum behaviors,” in the animal kingdom (let alone the obvious cases of vacuum morphology). i Richard Dawkins writes: The urge to feel 'grateful' in a vacuum, when there's nobody there to thank, is very strong.
