NCSE's Josh Rosenau will deliver the All-Academy Lecture at the Ohio Academy of Science annual meeting. Taking inspiration from Dobzhansky's maxim that "Nothing in biology makes sense except in the light of evolution," Rosenau will explore the ways in which evolution underpins modern science. From agriculture and medicine to computer science and astronautics, evolution is crucial to working scientists and to an informed citizenry. The spate of creationist legislation in recent years and continuing attempts to undermine evolution classroom by classroom continue to threaten the ability of the United States to effectively compete in the world economy of the 21st century. Today's teachers must be aware of these threats and how to address them, even as they give tomorrow's teachers the knowledge they need to prepare our children and grandchildren for the new century.
