Most people think of the "Missing Link" as the point where ancient humans evolved from earlier apes. However, a more difficult to find, and perhaps more significant, "Missing Link" may be the transition from water to land-dwelling animals about 150 million years before the dinosaurs. Science labels them and their descendants (including humans) as tetrapods (four legs). Click on the link below for a fascinating look into how our knowledge has expanded over decades in narrowing down the features of our first land-dwelling parents. If you have any doubts about the validity of evolution, this will slap you in the face with the reality of the matter.
