Join me in class, won't you?
You don't need that part. Luckily you don't have to satisfy every definition of a word at the same time. English would be impossible if that were true.
Selection is outside of the scope I gave you and for good reason.
I am speaking of biological evolution with no respect to behavioral science.
It is my opinion that behavioral science is bullshit and sexual selection is arbitrary. You didn't specify what kind of selection, either. There are countless different types of selection and factors that influence which animals mate and which ones do not.
The bottom line is that it doesn't matter. Look at the biological definition of the word. Every child satisfies the definition. It doesn't matter who the parents are or why.
Genetic science didn't exist when Darwin wrote his theory so don't act like it is the only source material on the subject. Many scientific theories have changed in the last 100 years. If you still function on outdated teachings then it is you who needs to return to school to learn about new developments.
