Evolution
Natural process of slow change and development that gradually leads to the development of new species, plants and animals over a very long time
Evolution is the process by which species of organisms change over time. It is driven by two main mechanisms: natural selection and genetic drift. Natural selection favors certain traits that help an organism to survive and reproduce in a given environment, while genetic drift refers to random changes in the frequency of genetic traits within a population.
The theory of evolution is based on the idea that species change over time through the gradual accumulation of small genetic changes. These changes can result in new adaptations that allow organisms to better survive and thrive in their environment. Over time, these adaptations can lead to the development of new species, as populations of organisms become reproductively isolated due to geographic or other barriers.
Evolution is supported by a vast array of evidence, including the fossil record, comparative anatomy and embryology, molecular biology, and studies of DNA and genetics. It is considered one of the most important and foundational theories in the field of biology, with far-reaching implications for our understanding of the natural world.
