Calling all freaks now
Hey, a commenter on my emu dissection post had a good question: what's the deal with wing claws in ratites? Are they inherited directly from other theropods--i.e., there was never a time when the lineage leading to ratites didn't have hand claws--or were they lost and then re-evolved within ratites, or what? Also, anyone know anything about their function, or lack thereof? Darren, Tom, Randy, Sarah, all and sundry--time to show what you know and expose me for the ignorant poseur I surely am.
