The eminent evolutionary biologist Ernst Mayr -- whom NCSE is proud to have among its members -- celebrates his 100th birthday on July 5. Writing in the July 2 issue of Science, he reflects on his eighty years of "watching the evolutionary scenery," from his education in Germany through the development of the Modern Synthesis to the discoveries of molecular biology. "[E]volutionary biology is an endless frontier," he concludes, "and there is still plenty to be discovered." NCSE is pleased to join its voice to the chorus of those around the world who are wishing Professor Mayr a very happy birthday.
