Darwin's Four Postulates
Diego De la Garza
The potential for a species to increase in number
Heritable genetic variation of individuals in a species due to mutation and sexual reproduction
Competition for limited resources
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.Bibliography
