Genetic deformities (warning may be disturbing)

  1. Jun 14, 2009 #1
    I think that we can learn a lot about genetic coding by analyzing extreme cases of deformity. For example, it's very common to see extra appendages -- this tells us that there is a low-level of redundancy in the code, and that there are just a few bits that control where a leg module should be formed...something like calling a subroutine. Also, notice that additional legs never break symmetry. Indeed every organism uses symmetry to condense coding.

    How many of those are genetic errors vs just unformed conjoined twins?

    This is a mix of very different cases. And tree man has been cured.

    His condition is improved (through surgery), but he looks far from cured...and warts have a tendency to grow back.

    It's interesting that black people can become albino (a white person), but a white person does not become a black person.

    Perhaps white people are genetic mutations black skin. (Actually, its more of a dark redish skin we are derived from. Black people are a darker version, white people a lighter version - or so I was told on a discovery show a while ago).

    It's actually quite a fascinating disease.

    Ugh! They should put that baby down once its born (or just abort it before its born) <yuck>


    Which leads me to ask, if they know a baby will be retarded before its born: why don't they just abort it? What is the point of giving birth to a handicapped baby: they only sad reason I can think of is "all Life is precious" nonsense.

    Exactly, it all comes down to that "life is precision" bunk. Personally I find it inhumane to put a human being through the suffering of life in that condition. At the stage of birth, a baby hasn't developed enough of a sense of self or unique identity to be precious...even if it does have some primordial sense of awareness.

    Agreed.

    Not everyone gets very good prenatal care and even with minimal care I'm not sure these things would be caught right away.

    Precisely. Even those that are not examples of conjoined twins, some are also developmental defects that can occur for reasons unrelated to genetics. A mother exposed to a toxin or with a disruption of blood flow to the placenta at a particular stage of development can lead to many abnormalities too.
