Evolution is the change in the heritable characteristics of biological populations over successive generations. Learn about the scientific theory of evolution by natural selection, the evidence for common descent, the diversity and history of life, and the fields and applications of evolutionary biology.
Hace 1 día · evolution, theory in biology postulating that the various types of plants, animals, and other living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations.
Aprende qué es la evolución biológica, cómo se explica y por qué es importante. Descubre cómo todos los seres vivos comparten un ancestro común y cómo se han adaptado a diferentes entornos.
Hace 3 días · Learn how evolution is the process of change and diversification of living things over time, and how natural selection is the differential reproduction of hereditary variants. Explore the concepts of gene pool, genetic variation, and fitness, and see examples of evolution in action.
Evolution is a peer-reviewed journal that publishes articles on all aspects of evolutionary biology. Browse the latest issue and editor's choice articles on topics such as adaptation, speciation, hybrid zones, parental care, and more.
All life on Earth shares a common ancestor, just as you and your cousins share a common grandmother. Through the process of descent with modification, this common ancestor gave rise to the diverse species that we see documented in the fossil record and around us today.
Evolution is a process that results in changes in the genetic content of a population over time. There are two general classes of evolutionary change: microevolution and macroevolution.
