Fitness the ability of an origins to survive and reproduce is adaptation fitness arises through a process called evolution change in species overtime is called survival of the fittest natural selection is also known as bird and reptiles share a number of inherited characteristics the principle of common descent helps explain why share a common ancestors with sea stars sea star larve resemble some primatibe vertebre this similarity suggests early vertebrae are best adapted to survive in their environment which line about individuals that live long enough to reproduces like natural selection population size is very large each of the following is a condition necessary for natural selection to occur except genetic variation sexual reproduction can speed up evolution because it provides more organic molecules scientists have proven that meteors comets and the dust in the universe contain spontaneous generation the hypothesis that mice can arise from spoiled grain is called natural selection populations of antibiotic resistant bacteria are the result of the process punctuated equilibrium brief periods of rapid change occur between long periods of stability according to
