- DNA: Human DNA is composed of about 3 billion base pairs, with approximately 20,000–25,000 genes.
- Body Systems: Major systems include the circulatory, respiratory, digestive, excretory, nervous, and reproductive systems.
- Life Span: The average human life expectancy varies globally, with estimates ranging from 60 to 80 years.
Cognitive Abilities
Humans have advanced cognitive capabilities that differentiate them from other species. These abilities include:
- Language: Complex language systems enable communication of abstract ideas.
- Creativity: The capacity for creative thought and artistic expression, resulting in literature, arts, and technologies.
