Darwin's Postulates - Synthesis
- Individuals within Species are Variable
- Some Variation is Passed on to Offspring
- In Every Generation, More Offspring are Produced than Can Survive
- Survival and Reproduction are not Random; Individuals who survive go on to reproduce, or who reproduce the most.
In every generation, more offspring are produced than can survive
Some of the causes for death of organisms include: disease, starvation, being eaten, etc. An environment cannot support the life of every organism born, which in turn creates competition and survival of the fittest, or rather, of the fit enough, results. Because only the better fitted survive and don't die off (most of the ones who die do so before they can reproduce), the favourable genetic traits that helped them survive are passed on.
