Epigenetics (changes in the course of life that alter the state in which genes are inherited) seems to offer explicitly science-based explanations for observations, rather than the decades-long usual: We can fit even this into Darwinism! For example, “Evolutionary psychology: The grandmother thesis, yet again” And also, of course, this: “‘Grandmother’ thesis in human evolution takes a hit.” (Shrug.)
That’s what’s killing Darwinism. For everything to fit in, the theory must be everything and thus nothing. For example,
Evolutionary psychology does not, for the most part, explain puzzling human behavior. It offers Darwinian explanations for conventional behavior that are intended to supplant traditional ones. For example, why we are sexually jealous (not fear of abandonment, but “sperm competition”); why we don’t stick to our goals (evolution gave us a kludge brain); why music exists (to “spot the savannah with little Pavarottis”); why art exists (to recapture that lost savannah); why many women don’t know when they are ovulating (if they knew, they’d never have kids); why some people rape, kill, and sleep around (our Stone Age ancestors passed on their genes via these traits), and why big banks sometimes get away with fraud (we haven’t evolved so as to understand what is happening).
Evo psych also accounts for anger over trivial matters (it was once key to our survival), dreams (they increase reproductive fitness), false memories, (there might be a tiger in that tall grass…), menopause (men pursuing younger women), monogamy (control of females or else infanticide prevention — of one’s own children only), music (to ward off danger), premenstrual syndrome (breaks up infertile relationships), romantic love (not an emotion, rather a hardwired drive to reproduce), rumination on hurt feelings (our brains evolved to learn quickly from bad experiences but slowly from the good ones), smiling (earlier, a cringe reaction), and wonder at the universe (explained by how early man lived).
It feels like emptying Darwin’s wastebasket.
