Consider this animal, the newest fossil discovery from Jianni Liu in China. She calls it "the walking cactus." We have grasses and flowers and beetles in more varieties than you can imagine, and yet, in some deep architectural way, the developmental paths were set way back then, 500 million years ago. The Walking Cactus is just another souvenir of that crazy moment.
