- GREAT MYTHS OF EVOLUTION: #1
- by David Menton
-
- HUMAN EMBRYOS HAVE "GILL SLITS" AT ONE STAGE OF THEIR DEVELOPMENT
- PROVING THAT MAN EVOLVED FROM AQUATIC, FISH AND AMPHIBIAN, ANCESTORS.
-
- You can hardly attend high school or college now days with out hearing
- or reading this "whopper".
-
- In fact, neither gills nor their slits are
- found at any stage in the embryological development of any mammal
- including man. The folds in the neck region of the mammalian embryo,
- that are erroneously called "gills", are not gills in any sense of the
- word and never have anything to do with breathing. They are merely
- flexion folds, or wrinkles, in the neck region resulting from the
- sharply down turned head and protruding heart of the developing embryo.
-
- These folds eventually develop into a portion of the face, inner ear,
- tonsils, parathyroid and thymus. No reputable medical embryology text
- claims that there are "gill slits" in mammals.
-
- Still, the gill slit myth is perpetuated in many high school and
- college biology text books as "scientific evidence" for evolution. Even
- Dr. Spock in his book 'Baby and Child Care' claims that "as the baby
- lies in the amniotic fluid of the womb, he has gills like a fish."
- Perhaps the "gill slit" myth continues to be taught because there is no
- better "evidence" for evolution. How many of you were taught the gill
- slit myth in school??
