The ears begin their development during the fifth week of pregnancy. Ear formation starts from a few small bulges called branchial arches. Portions of the branchial arches form into structures called auricular hillocks. The auricular hillocks grow and join together to form the outer ears.
During the fifth month, the inner and middle parts of the ear develop, but won't be completely finished until birth.

Carnivores Eg dogs cats have a little flap on the outer edge of their ears. It is almost like a little pouch. Does anyone know what it is for?
Good question! It is formed around the cartilage support of the "pinna" (outer ear/ear flap). It is most comparable to our own ear lobes. As far as I know it has no major function, like the lobes of our own human ears, but it's size and shape will be dictated genetically. It is most likely a remanant of fetal ear development in the womb.

It will begin to divide and divide becoming an embryo. It begins with one cell and continues until it is millions of cells and these will be seen:scalp vascular plexus, eyelid, eye, nose, auricle of external ear, mouth, shoulder, arm, elbow, wrist, toes separated, sole of foot and umbilical cord. It is called an embryo until about eight weeks after fertilization. After this development is considered fetal for the remainder of the pregnancy.

With treatment, the prognosis for acute otitis media is very good. However, long-lasting accumulations of fluid within the middle ear are a risk both for difficulties with hearing and speech, and for the repeated development of ear infections.
