Overview

Randomized trial reveals mechanisms of Neanderthal extinction linked to energy conversion rates.

Key Points

  • This research aims to resolve the debate on Neanderthal extinction by introducing the Energy-to-Information Conversion Rate (EICR) as a metric.
  • Introduced the Energy-to-Information Conversion Rate (EICR) under the Local Survival and Evolutionary Dispersal (LSED) framework.
  • Analyzed the energy expenditure and social structures of Neanderthals and Homo sapiens during the MIS 3–2 climate shifts.
  • Examined genetic divergence and population bottleneck signatures from ancient whole-genome sequencing data.
  • Neanderthals showed sustained irreversible genetic contraction, suggesting a significant decline in systemic resilience.
  • Modern humans exhibited recoverable population bottlenecks, indicating adaptive advantages.
  • Low EICR in Neanderthal populations restricted their ability to adapt to changing climatic conditions, leading to extinction.
