Embryological structures

Pere Alberch wrote that these differing embryological stages in homologous structures are "the rule rather than the exception". Sarfati continues: “ Plant embryology is one of the most important divisions of botany; its methods and goals are separate from those of plant morphology. General plant embryology explains the basic laws of the origin and development of generative and embryological structures (sporogenesis, gametogenesis, zygogenesis, endospermogenesis, embryogeny, apomixis). Many of the concepts associated with embryology were speculative until the invention of the microscope, which allowed detailed observation of embryological structures. Marcello Malpighi (1628 to 1694), an Italian professor of medicine and personal physician to Pope Innocent XII, was one of the first supporters of preformationism. Some organisms have anatomical structures that are very similar in embryological development and form, but very different in function. These are called homologous structures.

Some organisms have anatomical structures that are very similar in embryological development and form, but very different in function. These are called homologous structures. Since these structures are so similar, they indicate an evolutionary relationship and a common ancestor of the species that possess them.
