Human feet may not look reptilian once babies emerge from the womb, but during development the appendages appear similar to prehistoric fish and reptiles. The finding supports the theory that mammalian feet evolved from ancient mammal-like reptiles that, in turn, evolved from fish.

It also suggests that evolution—whether that of a species over time or the developmental course of a single organism—follows distinct patterns.

Well, better than feet of clay.
