Evolución humana. La evolución humana u hominización es el proceso de evolución biológica de la especie humana desde sus ancestros hasta la actualidad. 1 El estudio de dicho proceso requiere de un análisis interdisciplinario en el que se complementen conocimientos desde ciencias como la genética, la antropología física, la ...
La teoría de la evolución se centra en dos ideas básicas: que los seres vivos han cambiado a lo largo del tiempo, y que especies diferentes comparten ancestros comunes. Existe evidencia contundente que apoya estos hechos.

Evolution is the change in the heritable characteristics of biological populations over successive generations. It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.
Biological evolution is the process of change and diversification of living things over time, and it affects all aspects of their lives—morphology (form and structure), physiology, behaviour, and ecology.
