Humans

Humans are members of the species Homo sapiens, which means "wise man" in Latin. They are the only extant members of the subtribe Hominina and originate from Africa, where they reached anatomical modernity about 200,000 years ago.

Physical Characteristics

• Skeletal System: Humans have a complex skeletal system made up of 206 bones that provide structure, support, and protection for the body.
• Brain: The human brain is highly developed and is responsible for consciousness, thought, and complex problem-solving.
• Reproductive System: Humans reproduce sexually, with females typically giving birth to live young after a gestation period of around nine months.
• Sense Organs: Humans have well-developed sensory organs, including eyes for vision, ears for hearing, and a complex nervous system for processing sensory information.

Behavior and Culture

Humans are known for their complex social structures, language, and cultural diversity. They engage in a wide range of activities, including art, music, storytelling, and religious practices. Humans also have a significant impact on the environment and the other species with which they share the planet.
