Sure, but is a bad basis for morals. Like I said - social Darwinism is dodgy at best.
You know Darwin himself was against the idea. He argued that our ability to look after one another was one of the most vital parts of being human and we can’t save humanity by giving up our humanity.
Evolutionary biology is definitely no basis for a system of morality. But I must say, as a biologist who studied evolution, that social Darwinism is not based either on evolutionary theory or empirical evidence. The idea that evolution is driven solely by competitive ability is pseudoscience, and works neither in human nor animal populations.
Oh agreed! 100%!! Evolution has no morality baked into it just efficaciousness.
It may not be the happiest way to go but I think it’s the only self-consistent way to go.
As an individual I totally believe in making the world a better place, do unto others as that you would have them do unto you, all of that. But in the scenario where the world’s going to end unless one dude sacrifices themselves, I would say basic instinct kicks in. The tribe must survive!
