I was looking for stuff to post about the Burgess Shale because it's cool and Bayman at one point was going on about the Cambrian explosion being problematic. The burgess shale is a site in British Columbia containing many fossils from this evolutionary explosion of diversity.
However I found another blog entry at The Voltage Gate that basically kicks ass on how much effort I was going to put in. Check out this awesome blog entry on the Burgess Shale at The Voltage Gate. I was hoping to be able to find some more information on how the explosion might relate to the evolution of Hox genes, that is the genes that are largely responsible for body plan, but I was not very successful. Luckily first hit on Google I got was a link to an Intelligent Design quiz on the Cambrian explosion. I did find a couple of reviews that summerize research into Hox gene evolution that indicate Hox gene diversity predated the Cambrian explosion. I totally don't get it.
