Today is Darwin's 200th birthday celebration, and 150th anniversary of the publishing of 'Origin of Species'. Darwin is one of a handful of great scientists that have altered humanity's entire view of the universe.
It is already being celebrated internationally, informally. And it looks like there's growing support for making it an official holiday in the UK.
If you understand Evolution, then you can really begin to appreciate the beauty of all life. We are all related! Every, and I mean EVERY living thing on the Earth, past and present, is related to each other. Quite amazing.
