Natural selection - Wikipedia
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.

Nov 21, 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.
Natural Selection: Definition, Darwin's Theory, Examples & Facts
Jun 4, 2019 · Natural selection is the mechanism that causes evolutionary change, helping organisms adapt to their environment. Charles Darwin and Alfred Wallace published simultaneous papers in the subject in 1858, and Darwin subsequently published many additional works on evolution and natural selection.
Natural Selection - Stanford Encyclopedia of Philosophy
Sep 25, 2019 · For Darwin, natural selection is a drawn-out, complex process involving multiple interconnected causes. Natural selection requires variation in a population of organisms. For the process to work, at least some of that variation must be heritable and passed on to organisms’ descendants in some way.
What is natural selection? - Natural History Museum
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.
Natural Selection - National Geographic Society
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 – Definition, Theory, Types, Examples
Oct 26, 2024 · Natural selection is the process by which organisms with traits better suited to their environment tend to survive, reproduce, and pass those beneficial traits to future generations, leading to gradual evolutionary changes in a population.
Natural Selection - Understanding Evolution
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.
Understanding Natural Selection: Essential Concepts and …
Apr 9, 2009 · In its most basic form, natural selection is an elegant theory that effectively explains the obviously good fit of living things to their environments. As a mechanism, it is remarkably simple in principle yet incredibly powerful in application.
Natural Selection - Darwin, Then and Now
Natural selection logically explains the origin of Earth’s vast biosphere through “innumerable slight, successive” adaptations. However, stories of Darwin formulating his theory while comparing the beaks of finches on the Galapagos islands, while popular, are misleading.
