You may have heard the phrase "reproduce like rabbits" which means to have a lot of offspring quickly, much like it seems rabbits do when they mate.In 1896, J. W. Tutt suggested that the peppered moths were an example of natural selection. He recognized that the camouflage of the light moth no longer worked in the dark forest. Dark moths live longer in a dark forest, so they had more time to breed. All living things respond to natural selection. Over 100 other species of moth were observed ...Natural Selection in a Nutshell: Natural selection is the process by which individuals better adapted to their environments survive longer and reproduce more. Natural selection acts on phenotypes, or physical traits, that confer an advantage in fitness at the individual level, thus altering allele frequencies at the population level.
