A parent of a Year 5 student on the Sunshine Coast said his daughter was ostracised to the library after arguing with her scripture teacher about DNA. "The scripture teacher told the class that all people were descended from Adam and Eve," he said. "My daughter rightly pointed out, as I had been teaching her about DNA and science, that 'wouldn't they all be inbred'? But the teacher replied that DNA wasn't invented then."Earlier: Noah's Volcano.
