included the International Humanist and Ethical Union, Massimo Pigliucci, Amanda Chesworth, and Joann Mooney. D. J. Grothe continues to champion this effort among groups associated with the Center for Inquiry. The Center's branches across the world also organise Darwin Day events. Free Inquiry magazine, the flagship publication of the Council for Secular Humanism, and Skeptical Inquirer, the flagship publication of the Committee for Skeptical Inquiry, advertised the event and attracted further individuals and groups. The Secular Student Alliance, and other organisations committed to reason and rationality also participate in the annual celebration. With Robert Stephens, a scientist, as its President, Darwin Day Celebration has received support from scientists and science enthusiasts across the globe. Educators began to participate by offering special lessons to their students on or around 12 February. Darwin Day Celebration has joined COPUS, the Coalition on the Public Understanding of Science, reflecting an increased emphasis on science education and appreciation. Public relations emails to major publications led to coverage by media such as The Guardian in the UK, Scientific American, New Scientist, the Discovery Channel. In 2006 Darwin Day was covered by major news syndicates such as Associated Press, Knight-Ridder, and The New York Times. Over 150 articles appeared in major newspapers across the world and helped to attract more participants. Scientific organisations such as the National Center for Science Education, and the Linnaean Society, have endorsed the holiday. Scientists, philosophers, historians, and physicians lent their names in support of the effort, including Daniel Dennett, Steven Pinker, Eugenie Scott, Steven Jones, Elliott Sober, Sir John Maddox, Helena Cronin, William Calvin, John Rennie, Paul Kurtz, Carl Zimmer, Edward O. Wilson, Michael Shermer, Susan Blackmore, Michael Ruse, Richard Leakey, Niles Eldridge, and Colin Tudge. Musicians and entertainers such as Richard Miller and Stephen Baird also participated. In 2004, Michael Zimmerman, a professor of biology and dean of the College of Liberal Arts and Sciences at Butler University, founded the Clergy Letter Project in which over 11,100 clergy, as of 18 April 2008, have signed a declaration that a person of faith does not have to choose either belief in God or belief in evolution. In 2006 Zimmerman developed the Evolution Sunday movement. In 2007 lectures and sermons were presented to roughly 618 congregations across the United States and five other countries, on Darwin's birthday. Evolution Sunday is intended to show that faith and evolutionary science are compatible in many
