Human evolution encompasses the biological and cultural development of Homo sapiens. It involves studying fossil evidence, genetic data, and evolutionary mechanisms like natural selection. This field also examines the influence of culture and technology, tracing our ancestry through genetics and the fossil record to understand our origins and adaptations such as bipedalism and brain size increase.
