The order is not that important.
The fact that all of the steps are intertwined IS important!

1. Variation: There is Variation in Every Population.

2. Competition:  Organisms Compete for limited resources.

3. Offspring:  Organisms produce more Offspring than can survive.

4. Genetics:  Organisms pass Genetic traits on to their offspring.

5. Natural Selection:  Those organisms with the Most Beneficial Traits
                                            are more likely to Survive and Reproduce.

So what does all this have to do with the Meaning of Life?
