As millions of years pass, fish build on their basic design. The muscles around their backbone evolve into a powerful tail and fins appear. They evolve a distinct head. He may not look like you or I, but this odd fish is becoming a blueprint for our own bodies.
Walking with Dinosaurs was popular enough to inspire a stage performance, many spin-offs, and now a re-make. My favorite of these is the prequel Walking with Monsters: Life Before Dinosaurs. It is a 3-part series that tells the tale of evolution and life in the Paleozoic.
This is how we went from simple little swimming creatures to taking our first steps on land. A glorious moment in history.
Scientists explain the orangutan’s unique approach to problem solving with this example: If a chimpanzee is given an oddly shaped peg and several different holes to try to put it in, the chimp immediately tries shoving the peg in various holes until it finds the correct hole. But an orangutan may stare off into space or even scratch itself with the peg. Then, after a while, it offhandedly sticks the peg into the correct hole while looking at something else that has caught its interest.
