That is the value of history, it ensures a steady progression towards an ideal.(Though sometimes our ideas foster stagnation.) My question to YOU, is whether or not, as you put it, those "good genes" have gotten better. Are you BORN more intelligent than a fuedal serf, or an American colonist, or will someone from 2096 be NATURALLY more intelligent?
A question to ME is it
well I do think intelligence CAN be limited by genetics (see Brunner et al, fogot the date but it is late 20th century - a gene mutation caused the males in a family to develope mental retardation).
but I think its more to do with your upbringing for the most part. A person who experiences a colourful world and sees lots of different things and so has more scope to THINK about the world will be more intelligent than people who eat junk food and watch too much TV. Also honest education is key. Being told what to believe is bad for intellectual development while being given the tools to think critically is great.
Some peole may well be NATURALLY more intelligent, but the main factor is a healthy life experience.
Ideas are core to intelligent - and ideas do not exist in genes, they exists in the beliefs and values of a social group and of one's experiences.
