Next time a capital-letter Evolutionary Psychologist wants to claim DNA is destiny, tell him or her to think again, that we’ve found anciently-evolved snippets of mammalian DNA whose functions are still undetermined.
About 500 regions of DNA have survived largely unchanged for 80-100 million years. We know they’re not so-called “junk” DNA (more and more of which is showing itself to be not so junky after all), but we don’t know what it codes for.
See the rest of the story for more on what this might mean.
