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.
19. Okt. 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.
23. Mai 2024 · Learn how natural selection results in the adaptation of an organism to its environment by preserving and multiplying beneficial variations in its genotype. Find out how natural selection differs from mutation, migration, genetic drift, and sexual selection.

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.
Erfahre, was Selektion ist, wie sie natürlich, sexuell oder künstlich wirkt und welche Rolle sie für die Evolution spielt. Lerne die Definition, Beispiele, Selektionsfaktoren und die Bergmannsche Regel kennen.
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
Learn how natural selection is a mechanism of evolution that causes species to change and diverge over time. Explore examples of adaptations, exaptations, survival of the fittest and Darwin's finches.
