Hodgson, Vera Ignjatovic, Robyn Summerhayes & Elazar Kochva: Early evolution of the venom system in lizards and snakes, Nature 439, 584 -- 588 (2 February 2006)

This had already been prepublished online a few months ago. Now we learn (at last) that Nature's online pre-publications are not considered to have the official publication date.

Interesting how it uses "reptile" as something like "squamate" or "lepidosaur" or maybe even "toxicoferan", as in "[t]hese molecules [the large array of toxins] represent a tremendous hitherto unexplored resource not only for understanding reptile evolution but also for use in drug design and development" or "the complex and bioactive secretions present in 'non-venomous' lizards forces a fundamental rethinking of the very concept of 'non-venomous' reptile".
