Homo Sapiens

Homo sapiens is the scientific name for modern humans. They are the only surviving species of the genus Homo. Homo sapiens first appeared in Africa around 300,000 years ago and later migrated to other parts of the world, replacing other hominid species such as Neanderthals and Denisovans.

Anatomy and Characteristics

• Homo sapiens have a large brain relative to body size, enabling complex language, abstract thought, and problem-solving abilities.
• They are bipedal, meaning they walk on two feet, which distinguishes them from other primates.
• Compared to other hominids, Homo sapiens have a more gracile (slender) skeleton and a less pronounced brow ridge.

Cultural and Behavioral Evolution

• Homo sapiens developed complex social structures, language, art, and advanced tool-making techniques.
• They were capable of creating and using symbolic representations, such as cave paintings and sculptures.
• Early Homo sapiens were hunter-gatherers, but later developed agriculture, leading to the establishment of permanent settlements.
