Natural Selection | National Geographic Society

Oct 24, 2019 · 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 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. For example, some beetles are green and some are

Natural selection - Wikipedia
https://en.wikipedia.org/wiki/Natural_selection
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. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which in his view is intentional, whereas natural selection is not.

What is natural selection? | Natural History Museum
https://www.nhm.ac.uk/discover/what-is-natural-selection.html
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.

natural selection | Definition & Processes | Britannica
https://www.britannica.com/science/natural-selection
In natural selection, those variations in the genotype (the entire complex of genes inherited from both parents) that increase an organism’s chances of survival and procreation are preserved and multiplied from generation to generation at the expense of less advantageous variations. Evolution often occurs as a consequence of this process.

Jun 04, 2019 · Natural selection is one of the mechanisms that drives evolution. To be an active characteristic or trait causing natural selection to take place, the trait has to have the following features: Heritability. A trait can only influence evolution through natural selection if it is passed on from parents to descendants. Functionality.
