Evolution


I recently bought Richard Dawkins latest epic, “The Greatest Show on Earth” but I haven’t had the time to read it yet, what with the latest issue of Archie Comics having just come out. But the San Francisco Chronicle has this little gem from the book:

An “evolutionary arms race” pits cacti in the Galapagos against browsing tortoises, so the cactus grows taller to escape the browsers and the browsers evolve saddle-backed shells that enable them to stretch higher for the cacti.

I can’t wait. Tortoises AND cactus, together in one book! Exclamation points for everyone!

Science!

Here’s a copyrighted photo from Tom Dempsey that I “borrowed” to help illustrate this post.
