This is a load of shit. Why it has up votes blows my mind.

Do some reading or watching of hunter gatherer societies and you’ll see lots of group survival activities. Teamwork in hunts, in preserving food, in crafting tools, and making shelter.

If we were this self-centered, we wouldn’t have such advanced communication, which is how we were able to do all those group activities.

Survival of the fittest is survival of those that cooperate.
