Study reveals reasons for Neanderthal extinction.
Scientists are studying why Neanderthals died out. They think climate change, competition with humans, and disease were causes. There isn't one simple answer to this question.
Research shows Neanderthals had a fragmented population. This means groups lived apart from each other. Scientists found they were less connected than Homo sapiens. Around 65,000 years ago, there was a genetic bottleneck. This meant a loss of genetic diversity. The lack of variation made it harder for them to adapt. This research helps us understand how ancient humans disappeared.

Highlights
Seven Theories Exist
Scientists believe seven reasons could explain the Neanderthals' disappearance.
Fragmented Populations Key
Neanderthals lived in separate groups, isolated from each other.
Genetic Diversity Reduced
Neanderthals had less genetic variety than Homo sapiens.
Bottleneck Occurred 65,000 Years Ago
A genetic bottleneck happened around 65,000 years ago.
Low Genetic Diversity Led to Extinction
Lack of genetic diversity contributed to the Neanderthals' demise.
Perspectives
- Neanderthals died out due to multiple factors.
- Climate change was a significant cause of their extinction.
- Competition with Homo sapiens played a role.
- Genetic diversity was low around 65,000 years ago.
Some researchers believe climate change was the main factor.
