I question how useful this will be to us. Are the climbing adaptations in the
hoatzin young a primary feature, or was it secondarily derived? IOW, is this
something that evolved specifically in this critter, or is it a relic from
prehistoric times? If this is a special adaptation, it may point us towards
the right direction towards understanding our arboreal theropods, but we are
left with a huge gap to fill.
Perhaps it would be better if we had a few skeletal reconstructions of a few
dromaeosaur hands, as well as a few bird-dinos, and see how well they could be
used for climbing (gripping the branch, for example). Hey grad students! Want
a thesis topic?
