Caspar Friedrich Wolff [4] is most famous for his 1759 doctoral dissertation, Theoria Generationis [5], in which he described embryonic development in both plants and animals as a process involving layers of cells, thereby refuting the accepted theory of preformation?the idea that organisms develop as a result of the unfolding of form that is somehow present from the outset, as in a homunculus....
