Homo Sapiens
Homo sapiens is the scientific name for modern humans. It is a species of primates belonging to the family Hominidae. Homo sapiens are distinguished by their large brains and the capacity for abstract reasoning, language, and problem-solving.
Physical Characteristics
- Highly developed brain with a volume averaging about 1,400 cubic centimeters
- Bipedalism - the ability to walk upright on two legs
- Opposable thumbs for grasping objects
- Relatively hairless skin
Behavioral Characteristics
- Complex language and communication skills
- Cultural and technological advancements
- Ability to create and use tools
- Capacity for abstract thought and self-awareness
Evolution
Homo sapiens are believed to have originated in Africa around 300,000 years ago. They are the only surviving species of the genus Homo. The evolution of Homo sapiens is characterized by the development of advanced cognitive abilities and the ability to adapt to diverse environments.
