Study Reveals Social Networks Key to Human Survival in South Caucasus 57,000 Years Ago

A recent study led by Dr. Ariel Melinsky-Buller from the Hebrew University of Jerusalem challenges the long-held belief that environmental adaptation alone enabled hunter-gatherer populations in the South Caucasus to survive between 57,000 and 27,000 years ago. The research, published in Quaternary Science Reviews, integrates archaeological, geological, and paleoenvironmental evidence to reconstruct how small, dispersed groups navigated the challenging landscapes of present-day Armenia, Georgia, and surrounding areas.

Contrary to assumptions that these populations were isolated, findings indicate they maintained extensive social networks, traveling routinely between 40 and 200 kilometers. Stone tools and obsidian artifacts reveal shared technological traditions and knowledge exchange across wide regions, suggesting that social connectivity was critical for resilience during periods of climatic and ecological change.

The study offers new insights into the transition from the Middle to Upper Paleolithic era, showing a gradual cultural interaction rather than rapid population replacement. Dr. Melinsky-Buller emphasizes that survival depended not only on mobility and environmental factors but also on the maintenance of social ties and knowledge networks. "Our findings suggest that even small, scattered populations remained connected through networks of knowledge, technology, and social interaction, which may have been as crucial as environmental adaptation for enduring profound changes," he stated.

This research advances a comprehensive framework for understanding human adaptation by highlighting the combined roles of mobility, environmental conditions, population size, and social networks in prehistoric survival strategies.
