Neanderthal

Neanderthals were an extinct group of archaic humans, usually classified as *Homo neanderthalensis*, that lived in Europe and western and central Asia during the Middle to Late Pleistocene.

Neanderthals were an extinct group of archaic humans, usually classified as *Homo neanderthalensis*, that lived in Europe and western and central Asia during the Middle to Late Pleistocene. They were closely related to modern humans and interbred with *Homo sapiens* before disappearing about 40,000 years ago.

Classification and range

Neanderthals are usually treated as a separate species, though some authorities have classified them as a subspecies of modern humans. They inhabited large parts of Europe and western and central Asia during the Pleistocene. They are widely regarded as the closest extinct relatives of modern humans.

Physical traits

Neanderthals were generally shorter and more robust than *Homo sapiens*, with broad chests, strong limbs, and large skulls. Their bodies were short, stocky, and powerfully built. Average adult height estimates are roughly 1.50 to 1.75 metres, depending on sex and source.

Culture and behaviour

They used stone tools, controlled fire, hunted large animals, and are associated with burial of the dead and care for injured individuals. Some evidence also suggests complex communication and symbolic behaviour.

Extinction and legacy

Neanderthals disappeared by about 40,000 years ago, although exact timing varies by region and source. Their genetic legacy remains in modern human populations through ancient interbreeding. Neanderthal DNA survives in many people today, especially outside Africa.

Key facts

  • Neanderthals are regarded as the closest extinct relatives of modern humans.
  • They lived across Europe, the Mediterranean, and western Asia.
  • Their bodies were short, stocky, and powerfully built.
  • Evidence shows limited interbreeding between Neanderthals and early modern humans.
  • Neanderthal DNA survives in many people today, especially outside Africa.

Canadian context

Neanderthal research is relevant to Canadian readers through anthropology, archaeology, and human genetics, especially studies of ancient human migration and the genetic ancestry of modern populations.

Frequently asked questions

What is a Neanderthal?
A Neanderthal was an extinct archaic human, usually classified as *Homo neanderthalensis*, that lived in Europe and western and central Asia.
Did Neanderthals and humans mate?
Yes. Evidence indicates limited interbreeding between Neanderthals and early modern humans.
When did Neanderthals go extinct?
Most sources place their disappearance at about 40,000 years ago, though some estimates range as late as about 35,000 to 24,000 years ago in certain regions.
Neanderthal vs Homo sapiens
Neanderthals were generally shorter, more robust, and adapted to Ice Age environments, while *Homo sapiens* were more gracile overall. They were closely related and shared a common ancestor.
Neanderthal DNA in humans
Many people outside Africa carry small amounts of Neanderthal DNA, typically around 1% to 4% depending on the population.
How tall were Neanderthals?
Adult Neanderthals were usually about 1.50 to 1.75 metres tall, with males averaging around 164 to 168 cm and females around 152 to 156 cm in some estimates.
