Neanderthals

Neanderthals are an extinct species or subspecies of archaic humans who lived in Eurasia until about 40,000 years ago. They are our closest extinct human relative, and their DNA is still present in some modern humans. The study of Neanderthals provides valuable insights into human evolution, behavior, and adaptation.

Physical Characteristics

Neanderthals had a robust build, with a stocky, muscular body adapted for cold climates. They had a prominent brow ridge, large nose, and a cranial capacity similar to that of modern humans. Their physical characteristics were well-suited for the harsh environments they inhabited.

Lifestyle and Behavior

Neanderthals were skilled hunters and used tools such as spears, axes, and scrapers. They lived in small family groups and constructed shelters out of wood and animal hides. Evidence suggests that they had complex social structures and cared for their sick and elderly.

Genetic Legacy

Studies have shown that modern humans of non-African descent carry a small percentage of Neanderthal DNA, indicating that interbreeding occurred between the two groups when they coexisted in Eurasia. This genetic legacy has influenced traits such as immune system function, skin and hair characteristics, and susceptibility to certain diseases.

Extinction

The reasons for the extinction of Neanderthals are still debated among scientists. Possible factors include climate change, competition with modern humans, and changes in their environment. Regardless of the exact causes, their disappearance marked the end of a lineage that had thrived for hundreds of thousands of years.

Study Guide

Describe the physical characteristics of Neanderthals and how they were adapted to their environment.
Explain the tools and technologies used by Neanderthals and how they contributed to their survival.
Discuss the genetic legacy of Neanderthals in modern humans and the implications for human evolution.
Debate the possible reasons for the extinction of Neanderthals and provide evidence to support your arguments.

Studying Neanderthals provides a unique window into our own evolutionary history and the diverse ways in which early human populations adapted to their surroundings. It also challenges us to reconsider our definitions of intelligence, culture, and what it means to be human.
