Both wolves and humans are social creatures. They key ingredient is highly hierarchical structures. Where individuals compete among themselves for the position in the group. And capitalism is just reflection of that in human societies. First social creatures that "discovered" hierarchies were lobsters about 300 milion years ago. This is before even trees existed. Very long time from the evolutionary perspective, i.e. they do provide advantage to species that employ it.
