"Evolution Day is a celebration to commemorate the anniversary of the initial publication of On the Origin of Species by Charles Darwin on 24 November 1859. Such celebrations have been held for over a century, but the specific term \"Evolution Day\" for the anniversary appears to be a neologism which was coined prior to 1997. By highlighting Darwin's contributions to science, the day's events are used to educate about evolutionary biology."@en .
