My first comment. What a rush. And from ERV, one of my favorite science bloggers, too! She previously posted a great 'parentification' of this argument, and has promised to post a second, more detailed one soon. This is nice because I don't have to research all of the details and translate it, and because she is clearly much more of an authority than I on the subject so it will be 100x better that anything I could do. I'll post the link when it arrives.
