These lizards can live in a variety of habitats. Ground-dwelling populations of brown anoles live on lower parts of tree trunks and on the ground. These populations have long legs that help with jumping. The core of Darwin's theory is natural selection, a process that occurs over successive generations and is defined as the differential reproduction of genotypes. Natural selection requires heritable variation in a given trait, and differential survival and reproduction associated with possession of that trait.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 …The four steps or conditions necessary for natural selection to occur are that more organisms are born than can survive, characteristics vary within a species, variations are inherited, and differences in reproduction and survival are due t...KU Biodiversity Institute & Natural History MuseumMany German biologists conceived of life evolving according to predetermined rules, in the same way an embryo develops in the womb.

Natural selection is an inevitable outcome of three principles: most characteristics are inherited, more offspring are produced than are able to survive, and offspring with more favorable characteristics will survive and have more offspring than those individuals with less favorable traits. Natural selection and adaptation are natural tools that guide the evolution of all species. All beings that exist today are a result of these processes.
