Re: One for the bird brigade


    The hoatzin resembles _Archaeopteryx_ in that the young retain the hand
claws.  But, as Tom H. has pointed out, this is a reversal, not a retention
of the original character.  In terms of a 'look-alike' bird, the hoatzin
probably fits the bill.  We can examine them and their living habits (and
habitats) for some clues as to _Archaeopteryx_'s life.

    I tend to believe that all birds are _A._'s decendants.  However,  I
don't think that any existing birds are specifically close to _A._
evolutionary speaking.
