Medical Baby with two faces born

    I find it hard to swallow the explanation that cousin marriages are responsible. Guess humanity has been watching these marriages for centuries and nothing dramatic or too much of it has happened but why now ?

    Not for the weak heart

    This is a known but very rare condition caused by a mis-regulation of SHH protein. In developing chick arms this has been shown to cause odd symmetrical developments.

    Why is that? I don't know about this specific case but first cousin marriages many times result in abnormal offspring. It happens due to something called inbreeding.
