Utterly meaningless plug
One of my favourite podcasts is the Skeptics’ Guide to the Universe. Personally, I found the interview with ornithologist Richard Prum in the most recent episode utterly fascinating, so, in the extraordinarily unlikely event that you’ve come across my blog but not the SGU, go listen (and subscribe) to it now!
I’ve currently got experiments running every which way, which is why progress on The Voyage of the Beagle has been rather sluggish lately. I’m not going to explain this graph, but, suffice to say, if my hypothesis had been correct, the green line would have risen faster than the blue, maroon or orange lines.
