Well unfortunately the unintelligent are just as quick to pass there seed as an intelligent person. If fact recent stats say stupidity is spreading faster than intelligence. If humans were designed better we wouldn't even need to be talking about who is less intelligent.Nah, you'd think that with total random selection we'd have far more intelligent, rationale beings for the most part, because the gullible and intellectually deficient and virulent would have been mostly weeded out by now. Especially with all those hundreds of thousands of years of development allegedly involved.
