Surely the benefit of a learning and growing brain is that it can respond and adapt to situations faster than germ-line genetics ever could.
Absolutely, but it’s our genome that programs this adaptability.
Consider humans vs giant pandas for example. Our genes programmed our (brains and) bodies to be highly adaptable, some can be vegans, others carnivores, some can live in the snow, others in the tropics, we can learn new languages throughout life, and build novel tools and learn to use them. A giant panda might die if eats anything other than bamboo and will do poorly in any environment different than what it’s evolved for. This is because we evolved for adaptability while giant pandas evolved to be fit in a mostly unchanging environment.
Giant pandas probably don’t have the genetic adaptability built in for a dominator instinct to arise in them, while in humans, the dominator instinct can arise within our mental adaptability. It might start as meme (in the Dawkins sense) and then the brain can evolve to facilitate the behavior (to be honest, I think this is what is happening in our species currently, generations living under exploitative economic systems might be driving our brains to be less sympathetic to others rather than viewing others as part of our environment).
Why would there be a genetic limiter
It’s not that say giant pandas have evolved a genetic limiter really, it’s that humans have evolved to be able to survive in various and changing environments and a brain that can learn is a key part of this ability. Giant pandas have not had the selective pressure to evolve a genome tolerant of change able to produce a brain that can adapt on the fly to new environments.
Ah, I see, you just meant that other species don’t share our capacity for learning and adapting. Although, why do you continue to describe exploitative behavior as an instinct if you agree that it is a learned trait?
