Animals: a kingdom that includes birds, reptiles, amphibians, fish, mammals, Insects, spiders, clams, and lots of other organisms. It consists of all the selective pressures placed on plants and animals by the environment (such as wind or cold or drought) or by animals (such as predators or even members of the same species). Those poorly adapted do not survive to pass on their genes and those that are better adapted tend to survive and pass on their genes allowing the adaptation to persist into the future and possibly become more refined. Natural selection was first recognized by charles darwin.
