Climate Change Linked Disappearance

The disappearance of Neanderthals has been connected to the effects of climate change, which may serve as a warning. Although there are competing explanations for what happened to Neanderthals and why they vanished, one idea contends that climate change was the main factor.

Even while the environment was changing at a far slower rate than it is now when they lived, the changes were nonetheless severe enough to drastically reduce the number of species. Extreme examples of a dry climate and a cold climate alternated in Eurasia at different times. According to theory, this catastrophe not only decimated the Neanderthal population but also had an impact on animal populations, migration patterns, and hunter behavior.

According to the opposite hypothesis, the population of modern humans and Neanderthals dwindled over numerous generations until it vanished as a result of mating. The fact that more modern humans were migrating to Eurasia helped with this.
