Since Darwin’s theory of Evolution by Natural Selection was widely accepted, biologists have studied how this affects plants and animals. These effects can be seen clearly in sexual selection - where a trait that is, on the face of it, detrimental for an animal, such as a bird having a long tail that makes it difficult for them to fly, is selected for because of the female’s preference. Speciation - the rapid development of new species, is also seen clearly where small numbers of individuals are separated from the rest of the population, such as on islands e.g the Galapagos or Madagascar.
