Humans: A Comprehensive Overview

Introduction to Humans

Humans, or Homo sapiens, are a species of primate known for their advanced cognitive abilities, social structures, and complex cultures. Distinguished by their bipedal posture and highly developed brain, humans are the only surviving members of the genus Homo.

Biological Characteristics

Physical Attributes

Adult humans typically range from 4 to 6 feet tall and weigh between 90 and 300 pounds. Their bodies are structured with a head, torso, arms, and legs, consisting of a highly complex system of organs composed of systems such as the cardiovascular, respiratory, and nervous systems.

History and Evolution

Humans first appeared on Earth approximately 300,000 years ago, according to fossils discovered in Africa. Over millennia, they evolved through natural selection, leading to advancements in technology, art, and agriculture. Understanding human evolution helps explain behaviors seen in contemporary societies.

Achievements and Contributions
