    correct me if I am wrong, but didn't Darwin believe that learned
    behavior added to evolution?

    certain instincts come from DNA

    who is to say that learned behavior could not be added to the DNA in
    sperm and eggs?

    Sigh. I really should not be responding to an off-topic post, but...

    Darwin wrote about natural selection of inherited characteristics.
    (Actually, he wrote about a lot of things, including the succession
    process by which bare rock eventually becomes soil bearing vegetation.
    Back then, a "naturalist" studied everything.) The concept of
    "evolution" was already being batted around in both the natural
    sciences and in the popular imagination long before Darwin. What
    Darwin did was propose a mechanism by which it might happen, backed
    up by tons of observational data of speciation in currently living
    fauna.
    Which would make them inheritable traits, and therefore subject to
    natural selection.
    You have evidence of a workable "write to DNA" mechanism? That is an
    extraordinary claim requiring extraordinary proof.
    The teaching of young by parents is a more demonstratable method for
    transfering learned behavior from one generation to the next, at least
    for those species that have "parenting". In this case, the inheritable
    trait that might be favored by natural selection is a tendency for
    parents to spend time showing their young how to do things, and/or a
    tendency for young to imitate what they see their parents doing.
    More time consuming that simply inheriting skills, but much more flexible.
    For example, bears in Yellowstone have been observed teaching their cubs
    preferred methods for tearing open different models of cars; these skills
    cannot be more than a few decades old, and it would have taken thousands
    of generations for them to evolve genetically.

    you might be right, what I propose as inherited might just be taught

    With your constant OT babbling, you're inviting speculation about what's wrong
    with your DNA.

    I am certified nuts if that's where you were going ...

    then again I think everyone has a little of it in them
