Poor Social Networking Linked to Neanderthals Extinction: New Study

A new study by University of Cambridge and University of Montreal suggests weak social networks, not climate change, may have driven the extinction of Neanderthals.

Context: New research from the Universities of Cambridge and Montreal suggests that poor social networking, rather than climate change, was the primary driver of Neanderthal extinction.

About Neanderthals

Species Profile: Homo neanderthalensis was our closest extinct human relative, characterised by a robust build, large brows, and sophisticated tool-making abilities.
Geographic Range: They were widely distributed across Europe and Southwest Asia to Central Asia, successfully navigating multiple glacial periods.
Core Habitats: Simulations indicate they maintained stable “core” regions in Spain and Italy, which provided necessary shelter even during the volatile Marine Isotope Stage 3.
Cultural Sophistication: Evidence shows they practised burial rituals, used fire, and were highly adapted to cold-weather hunting.

How Neanderthals Went Extinct

The replacement of Neanderthals by humans was not a single event but a localised process; they disappeared at different times in different regions for varied social and demographic reasons.

The Social Connectivity Gap: Unlike Homo sapiens, who benefited from expansive networks along coastal migration routes, Neanderthal groups were increasingly isolated.
Demographic Pressure: Groups in regions like Eastern Europe were too fragmented to survive environmental or biological pressures, leading to a slow population collapse.
