State three structural features by which Neanderthal man differed from Homo sapiens.

Hint: Neanderthal men are the extinct species of archaic humans who live about 40,000 years ago. Due to the environmental changes, they became extinct.

Complete step-by-step answer:
Neanderthals are also included in the Homo sapiens and are called Homo sapiens neanderthalensis. They lived in or near east and central Africa about 40,000 years ago. They arise from the Homo erectus. The Neanderthal man has a brain size of 1400 cc. They used hides to protect their body and buried their dead. The Neanderthal man had a reduced chin, sloping forehead and a large nose. The Neanderthal skull is more extended and less globular compared to modern humans. They had a lighter skin colour and hair colour was regulated by the melanocytes stimulating hormones. The brain of Neanderthal had an extended larynx and had thicker bones, shorter limbs and barrel chest.
The Homo sapiens arose in Africa and moved across the continents and developed into different races. They are the most intelligent on the Earth. Humans have a more complex brain and developed highly advanced societies. Humans used fire and grew agriculture. Humans have no tail and have thinner body hair and sweat glands.

Note: Neanderthal men are the closest relatives of humans. The fossils of neanderthal man describe that they are separated by humans by about 50,000 years.
