Science is incapable of ever being truthful because every scientist is an amoral wannabee friend of Jeffrey Epstein. These nerds literally take lessons in school to learn how to beg for patronage to do research. Of course their studies usually end up being about managerial bourgeois praxis like using skull shape measurements to categorize workers. That's what personality psychology is about at the end of the day, Brave New World style eugenics with humane empathy for wage slaves.
You're right because European exploitation of Africa definitely didn't begin centuries before Darwin. Are you intentionally being obtuse?
Early evolutionary biologists held heinous views with regard to human evolution, no one disputes this. But frankly, white supremist views weren't unique to scientists in the 19th century. I'm not even really sure what your point is? Early biologists projected their racism onto human evolution, sure, but this in no way invalidates the entire field. They definitely weren't "mostly wrong" because as far as I know evolution is still our best way understanding speciation.
Yes.
You're right though, white supremacy had to already exist in order for evolutionary biology to work towards fabricating a scientific basis for it, which it did. And imperialism had to already exist in order for that fabrication to then justify New Imperialism, otherwise it wouldn't have been 'New'. Darwin had already been dead two years when the Berlin Conference rolled around.
The 'mostly wrong' this is mostly a semantic trick though, you got me there. That is more due to refinement than anything, any field 100 years on is going to be able to contradict most of the assertions of its forebearers
Edit: didn't realize this was in the science comm, probably wouldn't have posted like this if I had, but ah well it is what it is
