from the ZEBRAFISH. Many of the proteins in this species have been the subject of studies involving basic embryological development (EMBRYOLOGY).

In the embryonic diencephalon, a structure known as the eye cup develops, which will eventually become the retina, the nervous tissue of the eye called the retina. This is a rare example of nervous tissue developing as part of the CNS structures in the embryo, but becoming a peripheral structure in the fully formed nervous system.

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. These types of analogous structures do not prove species are related, but rather they support the Theory of Evolution by show how species do build up adaptations in order to fit into their environments. That is a driving force behind speciation or a change in species over time. This, by definition, is biological evolution.

An aortic arch is a branch from the arterial aortic sac to the dorsal aorta. It travels in the centre of each pharyngeal arch, embedded in mesenchyme.

Instead, if one understands how the configuration arose during the embryological development it starts making sense and is far easier to remember.Also, understanding this is essential to … Anatomical Evidence for Evolution.

Embryology Evolution Evidence. Darwin’s theory of biological evolution noted that all vertebrates have gill slits and tails in early stages of embryo formation, even though these features may be lost or modified in the adult-form phenotype.

31 The rectum above the pubococcygeal line develops from the primitive hindgut, while the rectum below this line develops from the cloaca. In the embryonic diencephalon, a structure known as the eye cup develops, which will eventually become the retina, the nervous tissue of the eye called the retina. This is a rare example of nervous tissue developing as part of the CNS structures in the embryo, but becoming a peripheral structure in the fully formed nervous system.

Do embryological structures function? In the third group [of vestigial organs] are structures that function only or primarily during some stage of development. Examples of this group are the notochord, the posterior cardinal veins, and the ducts of Cuvier.
