Marxist claims scientific proof for communism

You: okay how does that prove your point?

Stranger: It showcases how humans and other animals have developed through evolutionary means a factor of cooperation and mutual aid to help develop further. It showcases this through many ecological and biological studies. I’ve said this several times at this point.

Stranger: And your reply was nothing more than “no”

You: well on how does developing cooperations somehow disproves the greed exists as a human experience and not a product of capitalsim?

Stranger: And you’ve yet to even provide a source that proves your position

You: ....

Stranger: Because a trait that é lips based on cooperation and mutual aid is often times antithetical to a trait based on greed, as the two traits would often contradict one another. And is it not pretty self explanatory if we’re basing it off of “common sense” and such that you’ve tried to explain greed with? Look around. Are humans solitary creatures that do not work together and help one another? No. Humans strive for social interaction biologically. And the reason we have developed society to such an extent is the fact that we work at our best together with others.

Stranger: Is*

You: well one been antithetical doesn't disprove the existence of the other....

Stranger: Again, I’d yours now making a claim that a trait that would inherent stifle the growth of such a dominating trait humans developed almost exclusively to such an extent, by all means show me proof of that.
