@bitofhope@swlabr One of those quiet little scientific revolutions; cheap genetic testing let biologists realise that insects they had classified as different species were not, they were different morphs using the same genes. This let in the idea of developmental plasticity and the current consensus is that a whole lot of stuff is developmental, not genetic.
In humans, almost everything brain-based (sexuality, identity, language, symbol manipulation…) is likely significantly developmental.
@bitofhope@swlabr This completely messes with the idea that you can use “good genes” as a guarantee of a desirable outcome.
It also hauls in the idea of environment as the arbiter in more-difficult-to-ignore ways. Even if you’re using Origin and nothing since, you should be aware that “fitness” means “in some specific environment and moment in time”, only there’s this drive to ditch that. Recognising how much developmental plasticity matters breaks any concept of inherent quality of organisms.
