Au contraire, I maintain that it is *only* because of our arboreal ancestry
that we humans are bipedal. Specifically, I attribute our bipedality to
the occurrence of brachiation in our ancestors. All non-brachiating
primates are strictly quadrupedal. All *brachiating* primates, when on the
ground, show extremely unusual locomotor patterns - either obligate
bipedality or knuckle-walking. As far as I know NO brachiating primate is
a normal quadruped when on the ground.
So, no, I wouldn't find dromaeosaurs all that unique if they, or more
likely their ancestors, were arboreal.
