Document Summary
Changes pass on form one generation to the next. Hypothesized mechanism principle of use and disuse and principle of inheritance of acquired characteristics. The environment experiences by the parent can in uence o spring. Population showed great capacity to grow, but are ultimately limited by resource ability therefore species will never reach its max capacity created competition for the resources. Competition between individuals in a population for resources. Individual varywithin population in heritable traits related to competitive success. Some individuals more likely to survive and reproduce than others. Individuals may also vary within populations in heritable traits related to reproductive competitive success i. e the species that mate all have the same wing colours therefore those phenotypes will continue to remain in the population. Some individuals more likely to reproduce than others. Adaptive evolution: a population"s characteristics change over time, as advantageous traits become more common.
