🐋 Whale Evolution: From Pakicetus to the Blue Whale - Limb Loss and Swimming Lab

Slide 50 million years from the wading Pakicetus through Ambulocetus, Rodhocetus, Dorudon, Basilosaurus and Aetiocetus to the dolphin, orca and blue whale, and watch how paddling legs became a tail fluke. Test drag, Strouhal number, cost of transport, buoyancy and oxygen-limited dives, and compare skeletons to follow the shrinking hind limbs and the nostril moving to the top of the head.
