When were Neanderthals active? (ChatGPT, 2024-12-29)

 Neanderthals (Homo neanderthalensis) were active between approximately 400,000 and 40,000 years ago, though these dates vary slightly depending on discoveries and definitions. Here’s a breakdown of their timeline:


1. Emergence

Neanderthals likely evolved from a common ancestor shared with modern humans (Homo sapiens), possibly Homo heidelbergensis, around 400,000 years ago in Europe and parts of western Asia.


2. Peak Period

Neanderthals thrived during the Middle Paleolithic period (300,000–40,000 years ago).

They were highly adapted to cold climates and flourished during Ice Age conditions, particularly in Europe, the Middle East, and parts of western Asia.


3. Decline and Extinction

Neanderthals began to decline around 40,000 years ago, coinciding with the arrival of anatomically modern humans (Homo sapiens) in Europe.

The last known populations of Neanderthals lived in isolated areas like Gibraltar, with some evidence suggesting they persisted until about 37,000–40,000 years ago.


Coexistence and Interbreeding

Neanderthals and modern humans coexisted for thousands of years, and genetic evidence shows that they interbred.

Today, most non-African humans carry 1–2% Neanderthal DNA, indicating their genetic legacy continues.


Key Achievements

Neanderthals were skilled toolmakers, associated with Mousterian tools.

They exhibited complex behaviors, including:

Burial of their dead.

Use of symbolic objects (e.g., pigments, ornaments).

Possibly rudimentary forms of communication and social cooperation.
