It seems to me that Behe is now arguing that the putatively damaged APOB in polar bears lacks between 50 and 70% of the activity of its ortholog in brown bears (or maybe humans - it is not entirely clear from his use of the paper by Farese et al. just what the standard or control might be). Of course, he doesn’t offer any data to support this hypothesis, or otherwise argue that this explanation is better than that discussed by Lenski and Lents. But (good news, @Mercer) at least there is a hint of a testable hypothesis here. Regardless, APOB is still not the open-and-shut example Behe needs for his assertions to be correct.
Glaring (and, IMO, damning) by its omission is Behe’s refusal to address his blatant misrepresentation of Table S7 of the paper by Liu et al. One might think this to be an oversight, or maybe something that Behe may address come later. But, IMO, Behe’s extreme pettiness in refusing to name @NLENTS in the latest ENV piece suggests to me that Nathan’s essay hit closer to home than Behe will ever acknowledge.
Also, Behe suggests that Lenski is more well-known than Nathan. (“Echoing blogged arguments by his lesser-known co-authors …”) To be sure, Lenski’s research is impressive and has a respectable audience. But Nathan is a best-selling author, and it is possible that he is better known to the public than Lenski.
