Yes! Yummy. I spent all morning reading it and going off on its links, looking up stuff. That was a primo, nerd dork-heaven link. Thank you! :D :D :D
Did you see on that link where the mexican "fish" became a fully developed salamander when given iodine? And it had only been a "fish" because it had a kind of reverse evolution from land to water (to compensate for low iodine) rather than a conventional water to land evolution. The Iodine made it evolve "properly" to a land-based organism.
