Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
May 23, 2024 · Learn about the process of natural selection, which results in the adaptation of organisms to their environment by preserving beneficial genetic variations. Find out how natural selection differs from sexual selection, mutation, migration, and genetic drift.
Oct 19, 2023 · Learn how natural selection is the process of adaptation and evolution through genetic variation and inheritance. Explore the evidence, examples, and history of natural selection with Charles Darwin and his book On the Origin of Species.
Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift. Darwin’s grand idea of evolution by natural selection is relatively simple but often misunderstood. To see how it works, imagine a population of beetles: There is variation in traits.
Learn what natural selection is and how it explains evolution in living things. Watch a video and test your knowledge of fossils, adaptation and extinction.
Natural selection is a mechanism that makes any species - be it a plant, animal, fungus, bacteria, you name it - better adapted to their environment. For herbivores (i.e. plant eaters), the plants are indeed part of their environment.
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time. Natural selection is one of the ways to account for the millions of species that have lived on Earth.
