Adaptation to environment over time makes sense to me as well as an average advantage being replicated over time.

How many generations died from "random mutations" ? Your comment implies that those "Mutations" had a purpose. Without purpose, and given the survival rate of random mutations, the math simple doesn't work.

I’m not talking about mutations. As you can see from my comment, I was talking about variability already built into the DNA....thus, great danes and Chihuahua comment.
