is probably *TATA* – the lungfish.
OK, I spoiled the surprise, but if you have any interest in evolution, you should still read this excellent paper on the evolution of the first tetrapods in tomorrow’s issue of Nature. It’s just amazing what the molecular biology colleagues are pulling out of full genome sequencing data in the last years. Certainly also a handy paper for arguing with the occasional creationist that claims we don’t understand the pathways to key innovations in evolutionary history.
