Re: Origin of bird flight: ontogenetic-transitional wing (OTW) hypothesis
Yep. If They Existed (ITE), they weren't birds, they were cursorial critters
that used their gonna-be-wings-someday to catch insects. Or give a little
locomotive assist across the varied terrains where small increments of thrust
and/or lift can be advantageous to a biped.
