The recent ATS congress in San Francisco had a nice session of “Just so stories“. The stories written by Rudyard Kipling three years after the death of his six year old child from pneumonia these are still some of the best questions ever asked. Answers at the ATS were by provided (by Powel) “How the birds got air sacs”, (by Loring) “How the elephant lost his pleural space” and (by Sieck) “How the diphragm got its dome”. The best session at the ATS!, yea, yea.
