    Following scenario.

    1 pair of twin boys meets a pair of twin girls. And they fall in love.

    Pair A lives healthy! Eats good food, swims and runs alot. Works out. And this continues for years... they study alot of problem solving math and become smarter.

    Pair B eats junkfood, are lazy. Never do any workout. They drink and smoke alot and uses drugs from time to time. They just sit infront of their TV all day mindlessly watching lame tv shows.

    After 6 years they both get children.

    Will pair A have stronger, smarter and healthier children, even if they have the exact same genes?

    If this is true then evolution is undeniable right? And also if this is true isnt it selfish and almost evil of parents not to use a few years before having children to "improve" their genes for the sake of their offspring?

    Im by no means an expert, just curious!

    How much exercise? Too much isn't good either.

    No, this is not how evolution occurs.

    You cannot willingly change your genes in a desired direction. Save for a few chance mutations that may have occurred, your genes are the same from the day your parents' egg and sperm fused to make you until the day you die. And even those few mutations will not get passed on to your offspring unless they occurred in your eggs/sperm.

    What can best be said of couple A is that the mother is less likely to have health problems when bearing and giving birth to her baby, and her baby will probably be given better nutrition when in the womb. If couple A continues their habits, they will teach these habits to their child who will also live a healthy life. Couple A are helping themselves and their offspring reach the full potential their genes can offer by augmenting the environmental factors in a positive way. The child of couple A will probably grow faster, be taller, and have less health problems than the child of couple B despite their identical genome.
    Man can will nothing unless he has first understood that he must count on no one but himself; that he is alone, abandoned on earth in the midst of his infinite responsibilities, without help, with no other aim than the one he sets himself, with no other destiny than the one he forges for himself on this earth.

    It's not true. It sounds a bit like Lamarckianism, which is an old theory of evolution that has been debunked. Your genes are not altered by your behaviour in any controllable way. Certain lifestyles may make you more prone to mutation in your sex cells, but that's essentially random. Assuming we showed the offspring to have similar genetic fitness (they wont be identical between the couples due to chromosomal recombination) then genetic inheritance, not evolution itself, would be supported by that experiment. But nobody I know of denies genetic inheritance- even creationists know better than to fight that battle.

    If it were true it might be immoral, though that would depend on how fit the offspring would be to their environment. We're not putting them into a jungle with tigers. But it isn't true. Though you might want to read up on epigenetics, which sort-of what you're talking about.

    Curiosity is good. Assuming you are not an expert is good. :-D

    New hypothesis:

    You beat one of the twins and tell them they are worthless every day, meanwhile you treat the other as a God to an excessive amount.

    One grows up with emotional issues the other grows up to be a narcissist.

    That is one way we can affect our children.

    still, you can try and beat the shit out of someone, but you can't beat the DNA out of them

    The question seemed to be concerning just one generation span.

    Indeed. Otherwise I might have mentioned the Baldwin Effect!

    Over one generation you can affect your offspring rather drastically by environmental effects.

    If you don't believe me try to make a baby while you are doing your regular thing, and then make one while you are high on crack during the length of the pregnancy.

    I can assure you that the probability that you will be able to measure some effects that are normally associated with crack babies in the literature is high.

    I don't belive so. but there children might change from what genes they get and how there raised. But they might be alot different if there mutated from radiation.
    I appoligize for mistakes in grammar, puncuation, and spelling. Cuz i suck at that stuff.

    It's ok if you don't believe it, but unfortunately it is well documented.

    I believe that the point is, you can significantly affect the well being of your children without any concurrent genetic change. We are all well aware of what the OP said.
    Man can will nothing unless he has first understood that he must count on no one but himself; that he is alone, abandoned on earth in the midst of his infinite responsibilities, without help, with no other aim than the one he sets himself, with no other destiny than the one he forges for himself on this earth.
