Study finds modern hunter-gathers relocate to maximize foraging efficiency

As bumblebees forage for nectar from one flower to the next, at a certain point, they will move to another area once their search for food becomes too inefficient. This behavior, also observed among other animals, conforms to a prevalent model in biology called the "marginal value theorem." In like manner, groups of modern hunter-gatherers relocate their camps to maximize their foraging efficiency, according to a Dartmouth study published in the online Early Edition of the Proceedings of the Nat
