Darwin's Four Postulates

Diego De la Garza

The proliferation of those organisms that are better able to survive and reproduce in the environment

Some species and organisms are better at reproducing and surviving in certain environments. There are several reasons why this happens.

-Success of finding a partner

-Ability to obtain food

-Living long enough

-Number of offsprings that are produced

All of this traits equip organisms and help them live strong and fulfilled lives. This is normally called survival of the fittest.
