Im on a cell phone at a ball game, but its interesting that there was no attempt to address orphan genes and their role in evolution. Although the concept was ridiculed by Roger, I suspect it is that he simply doesnt know how to address
Orphan genes are protein-coding genes that appear in a single species. Because they appear only once in the evolutionary tree, they must have evolved relatively rapidly and their history cannot be traced back to early evolutionary history.

These orphan genes are also being found to be particularly important for specific biological adaptations that correspond with ecological niches in relation to the creature's interaction with its environment. The problem for the evolutionary model of animal origins is the fact that these DNA sequences appear suddenly and fully functional without any trace of evolutionary ancestry
