    I almost laughed up a lung at the rap provided in the show notes. “Herp-herp-herpes-herpes”. haha, so random!!! And Dickson's laugh after his intro in the rap was great!

    As for ERV's, they're my favorite argument for evolution (I occasionally debate with creationists (which is unhealthy for me, I'm sure)). They essentially >prove< evolution. I never use the word “prove” least of all in science, but statistically it is just impossible for all of the thousands of ERV sequences to exist in exactly the same loci, organized in a perfect nested hierarchy across the tree of life. Though I do get the occasional response to the ERV argument and it typically involves the cramped quarters on Noah's arc…….yeah, it's quite a strange argument that fails miserably.

    Great episode. I look forward, as always, to the next.

  2. I think what you were thinking of is actually called Monotremes. This includes echidnas and platypuses which are mammals that lay eggs.

  3. Oh, sorry, too early – you got it, sorry!
