Embryology is the branch of zoology that studies how organisms develop before birth, from the formation of sex cells and fertilization through the growth of embryos and fetuses. It includes the study of birth defects and other disorders that develop before birth, which helps us understand both normal development and what can go wrong during pregnancy.

Early embryology, put forward by Marcello Malpighi, was preformationist in concept: based on the idea that organisms develop from pre-existing miniature versions of themselves. The theory now accepted, epigenesis, is the idea that organisms develop from seed or egg in a sequence of steps. This concept was proposed in antiquity by Aristotle. Modern embryology developed from the work of Karl Ernst von Baer, though accurate observations had been made in Italy by anatomists such as Aldrovandi and Leonardo da Vinci in the Renaissance.
