Desai's test, while really interesting, sort of oversimplifies environmental input on selection. If a 100 relatively genetically basic organisms are subject to the same environment and selected in the same method, only specific mutations will be beneficial to population selections. The important point is that genetically similar yeast can be "fit" in the same way. But it seems to me these populations of yeast were selected for the same fitness, why is it a surprise that they show similar paths to get to that fitness? And also, since when is selection pressure the exact same over multiple generations?
Very cool experiment in it's scale and scope.

"There remain four irreducible objections to religious faith: that it wholly misrepresents the origins of man and the cosmos, that because of this original error it manages to combine the maximum servility with the maximum of solipsism, that it is both the result and the cause of dangerous sexual repression, and that it is ultimately grounded on wish-thinking." ~Christopher Hitchens, god is not Great
