 When on board HMS Beagle as naturalist. Hilleman fell in love with Darwin. I was much struck with certain facts. He literally like Darwin is what drew him to the dark side. Yeah. He told me the story with glee about how he would sit in church and seemed to me to throw some light on the origin of species. Read Darwin's on the origin of species. That mystery of mysteries. Unlike his dad's religion that was all about mystery.
