> They are born knowing how to walk

Most animals know how to walk. They have pre-build 'knowledge' and start with it when they get muscles. The main difference is some species develop muscles before they are borne. Others don't, some can't even see. But as soon as they develop they can walk without even seeing how others do it. The same way birds can learn, or be trained to fly without seeing examples. They start flapping both wings in sync, this is pre-build.
