I understand the basic genetic theory, but am shaving with occam's razor. Did anyone check?
Don't cut yourself.
Occam refers to two competitive scientific theories. I can't see another one. If you got ID in mind. Please keep it there. ID has no explanatory power.
I read the research this article is based on, if that's what you mean...
I find it highly unlikely a parasite or other external force is involved when they do controlled matings in the lab.
