Charles Darwin TheoryCharles Darwin Theory Charles Darwin (1809-1882) made a few main observations: * If all individuals reproduced successfully, the population sizes within all species would increase exponentially. * Except for seasonal differences, population sizes remain constant. * Resources (food, habitat etc) are limited. * Individuals within a population vary - some are more successful than others. * This variation is often heritable.
And because larger populations than the resources can support lead to struggle, he concluded that those individuals whose inherited characteristics suit their environment better than others are likely to leave more offspring than the less suited individuals. This is the theory of the survival of the fittest, which over the time will lead to a gradual change of the population, towards individuals that are better suited to their environment.
