This is almost certainly because humans and fish share some DNA and a common ancestor, not because we go though a “fish stage” when in our mothers’ wombs as part of our development towards
What Do Pharyngeal Pouches Develop Into In Fish? The lateral pockets of the pharyngeal cavity, called the pharyngeal pouches, perforate the mesodermal layer, reach the ectoderm, and break through to form pharyngeal, or gill, clefts. In fishes and larvae of amphibians, these clefts develop gills and become respiratory organs. What do pharyngeal pouches become? The
Do Humans Have Pharyngeal Slits? Do humans have pharyngeal slits? All chordates possess a tail and pharyngeal slits at some point in their lives, and humans are no exception. Early on in human development, the embryo has both a tail and pharyngeal slits, both of which are lost during the course of development. Is pharyngeal
