You have a knack for prose my friend, but your science is just no good.

Example 1, I assume you wouldn’t marry your sister, right? Why would that be? Because you do not want to 
procreate with genes that are too similar to yours. What does offspring of very similar parents have more 
chance of having? Genetic defects. Where do you think the term “Hill Billy” come from?

Example 2, it has been shown that the sense of smell is still important for humans for selecting a mate, 
because smell discloses particularities about your immune system’s genes. Which mates do people (and 
animals as well) prefer according to smell? That’s right, mates with a different genetic makeup. Why? 
because difference in genes strengthen your body’s defence systems against parasites and diseases.
