The malleus originated from the articular bone, whereas the incus originated from the quadrate bone. The microenvironment surrounding mammary tissue plays a pivotal role in the gland development, predominantly via regulation of epithelial-to-mesenchymal transition (EMT), during which epithelial cells lose cell polarity and cell adhesion to become mesenchymal cells with migration and invasion properties.

One of the main reasons whales can successfully breastfeed underwater is the milk’s consistency. The organs of the female reproductive system are specialized to produce ova (eggs), transport the egg cells to the site of fertilization, to provide a favorable environment for developing embryos, and to move offspring outside of the body (birth) at the appropriate time.
