Individuals with traits that allow them to be well-adapted to their changed environment reproduce in greater numbers than those without those traits. Individuals who inherit traits adapted through use in a changing environment have a greater chance of survival. Individuals that exhibit homologous structures with previous members of the population have a greater survival rate in changing environments. Individuals experience biochemical changes in lipids caused by the environment, which help them survive.
