Speciation - The creation of a new biological species, Convergent evolution - Two different species become more and more similar over a long period of time due to the environment applying the same selection pressures, Divergent evolution - Different selection pressures are applied to isolated populations of a common ancestor and new species evolve , Adaptive radiation - A type of divergent evolution where one species results in many species that are adapted to a variety of environments, Adaptation - A characteristic that helps an organism to survive and reproduce in its environment, Variation - A range of different phenotypes in a population due to genetic diversity, Selective pressure - A force that favours organisms with genes encoding advantageous traits, Natural selection - The process where environmental pressures gradually change a population so that advantageous traits for that environment are favoured, Artificial selection - The process where humans selectively breed organisms with desirable traits, Mutation - A change in a DNA sequence giving rise to new traits, Gene pool - All the alleles within a population, Gene flow - The movement of alleles between populations due to immigration and emigration, Isolation - In evolution, separation of two groups of an ancestral population by barriers preventing breeding,
