Natural Selection - National Geographic Society
https://www.nationalgeographic.org/encyclopedia/natural-selection/
WEBOct 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 - Wikipedia
https://en.wikipedia.org/wiki/Natural_selection
WEBNatural 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.

Natural Selection - Understanding Evolution
https://evolution.berkeley.edu/evolution-101/mechanisms-the-processes-of-evolution/natural-selection/
WEBNatural 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.

WEBKey points: Charles Darwin was a British naturalist who proposed the theory of biological evolution by natural selection. Darwin defined evolution as "descent with modification," the idea that species change over time, give rise to new species, and share a common ancestor. The mechanism that Darwin proposed for evolution is natural selection.

WEBBy Emily Osterloff. 2669. 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.

WEBDarwin's theory of evolution by natural selection underlies all modern biology. It enables us to decipher our genes and fight viruses, as well as to understand Earth's fossil record and rich biodiversity. Simple and at times controversial, misunderstood and misused for social goals, the theory remains unchallenged as the central concept of biology.

WEBNatural selection is a mechanism of evolution and explains how species adapt to their environment over time through variations in traits. Examples include the peppered moth adapting to industrial pollution, yearly flu virus changes, and antibiotic-resistant bacteria. Understanding natural selection is essential for studying living systems.
