The British atheist group released this set of posters in honor of Darwin Day on February 12. This year marks Darwin's 200th birthday and 150 years of his theory of evolution. The BHA last made news for its controversial atheist bus campaign in London.

Copy from the poster: In 1859 Charles Darwin published his book On the Origin of Species, controversially challenging the conventional view of the creation, with his theory of evolution by natural selection, a debate still raging today. Join us to celebrate both the 150th anniversary of one of the most revolutionary and influential scientific theories ever conceived, and the 200th anniversary of Darwin's birth.

We are working with the Darwin 200 coalition and coordinating our own celebratory events. If you would like more information about our celebratory events during 2009, Darwin Day lectures or the international campaign to make Darwin's birthday a public holiday, please contact us at [email protected] or log onto our website www.humanism.org.uk.
