I almost forgot.
This is the day that in 1809 Charles Darwin, who traveled the world, study life in many of its forms, and developed the basics of what would be our current understanding of Evolutionary Theory, was born.
The theory has moved on some since his day. And even then he was not alone in seeing where the evidence was pointing. But his hard work, willingness to suffer haranguing, and move science forward should be long celebrated.
It can be happily said that the world is a far better place for his presence and his efforts.
