Why do fetuses develop pharyngeal slits?

The development of pharyngeal slits in fetuses is believed to be a call back to our evolutionary history. As I'm sure your aware humans and any living vertebrates belong to the phylum Chordate which is part of the Deuterostomes branch of the animal kingdom. You may have heard about the theory of how modern day mammals and so hence man evolved from fish. Well the presence of pharyngeal slits in fetuses is one piece of evidence for this theory. As pharyngeal slits are used in simple organism such as Hemichordates to filter feed in water. Organisms classified as Deuterostomes are done so by the presence of these pharyngeal slits at some stage during their development ( In fish embryos it is the pharyngeal slits which develop into the gills), amongst some other similar developmental patterns. I hope this helps to answer your question.
