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.
Oct 19, 2023 · Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
Natural selection is a process by which a species changes over time in response to changes in the environment, or competition between organisms, in order for the species to survive.
Sep 25, 2024 · natural selection, process that results in the adaptation of an organism to its environment by means of selectively reproducing changes in its genotype, or genetic constitution. A brief treatment of natural selection follows. For full treatment, see evolution: The concept of natural 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.
Nov 10, 2023 · Learn how natural selection is the adaptation strategy of living organisms on Earth that leads to evolution. Explore the theory, examples, and types of natural selection with a diagram and a simulation.
Natural selection is one of the ways to account for the millions of species that have lived on Earth. Charles Darwin (1809-1882) and Alfred Russel Wallace (1823-1913) are jointly credited with coming up with the theory of evolution by natural selection, having co-published on it in 1858.
