David Puts : To find your perfect mate, think like an evolutionist

David Puts at TEDxPSU  (transcript)
To find your perfect mate, think like an evolutionist
Summary
First, I thought that a mate in the title was a classmate or workmate, somehow, it's wrong and then the important thing is why the words “an evolutionist ” is used.

My opinion is that there is an idea that is a designer baby must be normal from now. Our basic is that leaving better genes and species thus mating might not be necessary. We are now surprised, however, it's the same as we didn't believe about evolutionism.
Evolutionism describes the belief in the evolution of organisms. Its exact meaning has been changing over time as the study of evolution has progressed so we have to progress the idea more that is evolutionism. Our heart and brain have many things that we don't know yet, though, we are humans. As humans, leaving better genes must need our love.
