Hunting prey is a much more dangerous endeavour than foraging for fruits/veg, for obvious reasons. And , like I said before, what we count as wild does not resemble the much larger biomass that existed in the Palaeolithic era. You have to remember that there were vast forests in that era with plentiful plant-life, fruits etc. And fruits/plants don't only ripen in the summer, incidentally -I've been to national parks in cotober/november and eaten garlic leaves in huge amounts.
Statistical factors, such as danger have no place, where man is instinctual & naturally aggressive, similar to carnivores
Man hunted not only for nutrition, but also for protection & naturally & instinctively kept their land's free from pest's like deer & wolves from over populating their habitat
Hunting also sharpened & honed their skills, for keeping the more dangerous animals in check
Without hunting, modern man would probably be extinct in its present state
Culture & traditions, such as hunting are far more instinctively & in nature more important, then simply foraging
Try placing a human colony in a natural environment & see how long they last, without hunting to keep their local habitat free from predators & fauna
Even mostly vegetarian or forage tribes, have to hunt, its a given for any natural environment, whether they eat their prey is down to their cultural & social factors, ie medicine & shamans, as is today
Statistical factors, such as in anthropology, do very little to understand tribes & primitives, you HAVE to research how they function as a WHOLE, ie their societal & cultural values & their natural states as translated in nature
