A Consideration of How Natural Selection Shaped the Sociobiology of Hunting and Gathering
Published online by Cambridge University Press: 13 December 2025
Teleonomic interpretations of human evolution question whether behaviors like hunting, meat-eating, food sharing, and intra-group cooperation existed in extinct hominins. This perspective assumes H. sapiens as the pinnacle of hominin evolution. However, such behaviors may not require the complex cognitive capacities of modern human brains. Early H. erectus, with brains within the lower range of modern humans and more robust, agile anatomies, may have been highly efficient foragers. Their adaptive success likely stemmed from culturally selected behaviors rather than advanced cognition alone.
The gracilization of H. sapiens may be rooted in shifts in reproductive and social behaviors rather than improvements in foraging strategies. Brain expansion in our species was likely driven by the evolution of complex communication, symbolism, and social interaction, forming the basis of modern human social networks. This alternative perspective generates testable hypotheses regarding behavior preserved in the archaeological record. Under this model, hunting emerges as a byproduct rather than a driver of early human socio-reproductive structures.
