Back around the start of the earthquakes I was putting some old cartoons of Darwin on the Sandwalk (his private walk around the woodland at his estate which he ambled about most days to get in some serious thinking time) online. I have been doing my once a decade office tidy and came across some more Darwin on the Sandwalk from 15 years ago or so. The idea was that it would be useful to know what Darwin thought about as he paced the Sandwalk. Another complementary theme was using this to explain why Darwin took so long to write and publish ‘On the origin of species’. These cartoons first appeared in SYSTANZ newsletters in the 1990s. I also found the short-lived Unrootedtreeman cartoons. Expect to see them soon. Enjoy.
