Detailed explanation-1: -Populations evolve. Because individuals in a population vary, some in the population are better able to survive and reproduce given a particular set of environmental conditions. These individuals generally survive and produce more offspring, thus passing their advantageous traits on to the next generation.
Detailed explanation-2: -They are: mutation, non-random mating, gene flow, finite population size (genetic drift), and natural selection.
Detailed explanation-3: -Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds.
Detailed explanation-4: -Answer and Explanation: Darwin’s finches are an example of speciation because they developed specialized beaks dependent on the type of food they ate, adapting to their food source and environment.
