Gary Novak (mushroom physiologist) says he has evolved yeast into morel mushrooms in the lab, mocks ID, and joins the fray (go here). What Novak has actually shown, so one of my close ID biologist colleagues informs me, is that when he tries to grow wild morel mushrooms on artificial nutrient media in laboratory Petri dishes, they don’t develop beyond the single-cell stage — like yeast (a single-celled fungus). No evolution. Not even devolution. Just stunted growth. Say it isn’t so.
