Gill slits & Biogenetic Law

For decades, even up to this day, evolutionary textbooks have promoted the idea that mammalian embryos have gill slits. Sometimes they are called bronchial pouches, or arches. But no matter what the name science is trampled underfoot in the name of questionable belief systems. At any rate, the concept of gill slits is one of the greatest frauds perpetuated in the name of "evolution science".
