    If aging is reversed…..is evolution then reversed or furthered?

    The rise in Melanoma diagnosis makes sense given the incentives for doctors to play it safe under the current tort environment.

  2. Stephen C. says:

    I don’t see why evolution can’t be reversed. Is there some principle in physics that makes it impossible?

  3. Bart Ingles says:

    The additional five mutations, which had no effect on the new gene function but which prevented reversion to the old form, could be considered a manifestation of entropy. So it makes sense that things would tend to go in only one direction.

  4. Larry C. says:

    OK Bart, I hope the same principle doesn’t prevent reversal of aging.
