    As long as we assume that genes in some way contain the structure of the
    body, then the passing on of acquired characteristics is impossible.
    Acquired traits can't directly change the genome. But keep in mind that
    Darwin rejected the notion of units of "germ-plasm" coding for units of
    bodily structure.
