We evolved to what we did because of our ability to cooperate (or rather there were selective pressures where this ability was considered advantageous) - it is the social structures, generational knowledge passed down and the cognitive abilities including language, empathy etc that evolved with it that allowed us to climb the top of the so called food chain. The selective pressure (in the evolution of human beings) is vastly in favour of cooperation. This is also evident in multiple aspects of nature; heck even the process of evolving from unicellular to multicellular organisms.

This is basic biology and therefore he is lying. He is essentially talking about "survival of the fittest" the way layman may talk about it, not how the scientific discipline of biology would actually consider it.

All life forms could be considered a spectrum from cooperative cells to malignant tumours and to only consider one end of the spectrum and not the other especially if it is your discipline isn't just wilfully ignorant; it is straight up fraudulent.

This is also ignoring the fact whether being "natural" is a good in itself. Is ebola or childhood retinal blastoma "good" because they are natural?

Book recommendation: The Dialectical Biologist by Levin and Lewontin.

(I would not necessarily argue with him unless you want to make clear you're not going to deal with his nonsense. He is clearly not speaking in good faith. Like why the fuck did he study biology; to pass witness on the world as is and not to alter it anyway given the immortal goodness of its naturalness? Some Nietzschean BS.)

I would also internalise this article - it explains the birth of the modern West and how capitalism takes credit for socialist pressures without which there is no development as we know it (as this is really the subtext he was alluding to):

Furthermore, pointing out that Einstein considered himself socialist usually causes some congitive dissonance to these STEM right wingers:
