Yes, large groups to compete and fight with others, that what I meant.
Although, I do not know whether humans really had groups or unions significantly larger than 150 before the Neolithic age. If not, maybe this property developed in the last 10 000 years. Or maybe this whole idea is not true - I am not really competent to be sure.
