[QUOTE="Margonme, post: 1386027, member: 25776"] Jogeephus stated: [b]I don't know about that. I'm sure there are born geniuses but I believe its a combination of things with the primary reason being environmental factors and I suspect the reason IQ's are dropping is the wrong people are doing most of the breeding. Just my opinion. [/b] Jo, Everyone agrees that whether it be a cow or a human, what we are is a function of the interaction of genotype and environment. What is disputed is to what degree the environment influences the genotype. That debate has never been settled. I have always leaned toward genotype having the most influence. Let's use Cattle as an example. I have a Grandmaster calf that has excellent docility. He is 2 months old and I can pet him in the pasture. I have haltered him at least a dozen times. I reward him, pet him and treat him very gentle. He responds with even greater docility. Thus, I created an environment which has fostered his docility. I have an Uno Mas Calf born the same time, gone through the same training and is not responding as well. You cannot approach her in the pasture and scratch her tail head. She is by nature more shy and flighty. Why? Genotype. Same way with intelligence and that is the point CB made above. You can put a youngster in the best environment possible to foster intellect and they will underperform if they do not have the genotype to provide the fundamental aptitude for learning. I know a personal example I could cite: two youngsters raised in the same environment. One is extremely intelligent, the other struggles to pass. [/QUOTE]
