NCSE's current logo was created in 2007 by graphic artist Andrew Conti. He describes it as follows: "I have taken Charles Darwin's original notebook sketch of the tree of life and reworked it with rounded and more organic lines. By doing so, it is my intention to give a sense of open-minded and creative playfulness, while at the same time tying a direct link to the science and history of scientific understanding that is the focus of the NCSE."
