Junk Dna Debate
The short version of this debate is that Larry Moran and Dan Graur and T. Ryan "Onion Test" Gregory are right, and ENCODE and their hundreds of millions of dollars and everyone else who made claims along the lines of "we used to think most of the genome was junk because it didn't code for DNA, but now we have shown it's mostly functional" is wrong.
Someone asked for T-shirts. We actually made these for the 2013 SMBE meeting! Dan Graur wore one!
