The Early Man

Neanderthal man was an early human form classified as Homo sapiens neanderthalensis, known for a strong body, heavy skull features, and cave-dwelling life.

Key features:

• Lived about 150,000 to 25,000 years ago.
• Fossils were discovered in the Neanderthal Valley of Germany in 1856.
• Body was short, strong, and heavily built.
• Forehead was low and sloping, brow ridges were prominent, and chin was absent or poorly developed.
• Cranial capacity was about 1450 cm³.
• Used flint tools and animal skins.
• Lived mainly in caves and moved in groups.
• Buried the dead, showing the beginning of social and emotional development.
• Did not practice agriculture or animal domestication.

Cro-Magnon man was an advanced early human form classified as Homo sapiens fossilis, considered closer to modern humans in body form, intelligence, and culture.

Key features:

• Lived about 50,000 to 20,000 years ago.
• Fossils were discovered in Cro-Magnon, France, in 1868.
• The body was tall, erect, and strongly built, with a height of around 180 cm.
• Cranial capacity was about 1660 cm³, greater than that of many modern humans.
• Forehead was higher, brow ridges were reduced, and chin was better developed.
• Used improved stone tools, ornaments, and weapons.
• Used fire, wore animal skins, and lived as hunters.
• Showed cultural development through art, ornaments, and belief systems.
• Did not practice settled agriculture or domestication.

Modern man is Homo sapiens sapiens, the present human form characterised by advanced brain function, developed speech, culture, and civilisation.

Key features:

• Appeared about 11,000 years ago and continues to the present.
• Fossils have been reported from regions such as France, Java, and South Africa.
• Posture is fully erect, and the body is well balanced for efficient movement.
• Skull has a high forehead, reduced brow ridges, and a well-developed chin.
• Average cranial capacity is about 1350 to 1400 cm³.
• Cerebrum is highly developed, supporting reasoning, memory, language, and planning.
• Agriculture, domestication, organised society, and civilisation became possible.
• Tool use became highly advanced and diversified.

Evolutionary changes seen in modern man:

• Fully erect posture.
• Spine with proper curves for balance.
• Larger and more efficient cerebrum.
• Improved speech and communication.
• Reduced jaws and brow ridges.
• Prominent chin and broader chest.
• Forward placement of the foramen magnum due to erect posture.
