Neanderthal Decline Linked to Climate and Isolation Risks

Summary

Story summary

Neanderthal populations declined around 75,000 years ago due to a cooling climate, reducing genetic diversity.
The decline contributed to their eventual extinction, with groups confined to south-western Europe.
After 60,000 years ago, a new lineage emerged in southwestern Europe, but overall population growth remained limited.
An individual named Thorin, found in France, belonged to an older lineage, and experts say small, isolated groups increased extinction risk.
