When we look at feats of human engineering, like vehicles, skyscrapers, and computers, we don't doubt our intuition that they're intelligently designed. But when it comes to marvels of the natural world, like bird wings, whale flippers, and our own arms and legs, we're expected to suspend our design intuition and credit a gradual, undirected evolutionary process. Bio-engineer Dr. Stuart Burgess has been studying vertebrate limbs for over thirty years. On this episode of ID The Future, Burgess shares his cutting-edge insights on the universal optimal design of vertebrate limb patterns and the implications for fields like robotics.
