The intricacies of living bodies and their development have fascinated biologists, physicists, and thinkers alike. For biology, early studies in embryology provided evidence of evolution by common descent and other “missing links” among species. Before being observed directly, it was inconceivable that developing humans could have gills and tails, that our hands and feet first develop as fins, and that most of us have hidden teeth.
