Final answer:
Human diversity comes from a combination of biological and social factors. All humans share a common ancestry and basic biological traits.
Step-by-step explanation:
Human diversity comes from a combination of biological and social factors. Biologically, humans have evolved in response to different environments, leading to variations in traits such as skin color, eye shape, and hair texture. Socially, humans have developed diverse cultures, languages, and belief systems. Despite these differences, all humans share a common ancestry and basic biological traits, such as the ability to walk upright and use language. The development of humans in the first place is still a topic of scientific debate, but current evidence suggests that Homo sapiens evolved in Africa approximately 200,000 years ago and then spread out to other parts of the world, eventually replacing other human species.
