without our brainpower we would be close to the bottom of the food chain... am i right? a human is slow compared to most mammals, a human is weaker then all predators around our size. a human has bad vision, hearing and smell sense compared to the rest of the earth creatures. (special cases not counted) humans no longer have the "fur" to live naked in northern countries during winter. so basically without our brains advantage over the rest of the animal kingdom we would be toast. my question is this. is the development of the brain controlled by us and our will to explore and improve. is it our wants and desires that get programmed into our genes and passed on to our kids? say if someone with 120 and 110 iq have wanted to be smarter their entire life. then they get a child. as an adult... would that offspring have a better chance for more mental capacity then children of 120 & 110 iq parents that are happy with they iq and never gave it another though?. for the sake of objectivity. lets say these 2 children would be placed in identical foster homes and had no contact with their original parents.
