I was looking through the pictures from our 2009 trip to Australia for some garden images to enter in a contest. I found this image of a sculpture in the Sydney Botanical Garden that is inscribed with Darwin's words. Darwin visited this garden on his travels. This was a celebration in 2009 with the mirrored sculptures forming the name Darwin, and were a celebration of the 200th anniversary of his birth and the 150th anniversary of the publication of his book, On the Origin of Species.
Charles Darwin's observations of Australian floral and fauna during his visit in 1836 formed a key part in the development of his theory of evolution through natural selection and his subsequent publishing of Origin of Species.
