Evolution

In biology, evolution is the process by which populations of organisms acquire and pass on novel traits from generation to generation, affecting the overall makeup of the population and even leading to the emergence of new species.

The development of the modern theory of evolution began with the introduction of the concept of natural selection in a joint 1858 paper by Charles Darwin and Alfred Russel Wallace. This theory achieved a wider readership in Darwin's 1859 book, The Origin of Species. Darwin and Wallace proposed that evolution occurs because a trait that increases an individual's chance of successfully reproducing will become more common, by inheritance, from one generation to the next, and likewise a trait that decreases an individual's chance of reproducing will become rarer. This work was pathbreaking and overturned other evolutionary theories, such as that advanced by Jean Baptiste Lamarck .

In the 1930s, scientists combined Darwinian natural selection with the re-discovered theory of Mendelian heredity to create the modern synthesis, now one of the fundamental scientific theories of biology. In the modern synthesis, "evolution" is defined as a change in the frequency of alleles within a population from one generation to the next. This change may be caused by different mechanisms, including natural selection, genetic drift, or changes in population structure (gene flow).
