Tamara once again exposes the myths of evolution, even though she's not anti-evolution. Oh. Kay.
From
this discussion of several anti-evolution myths, Robyn Conder Broyles asserts:
quote:
The slits to which the author is refering are, in the strict sense, not gill slits (and no reputable anatomist would claim that they are, evolutionist or not), but they are by no means "merely flexion folds, or wrinkles," either. They are slits which form between the branchial arches, which all chordates have; in fishes, they develop into hightly specialized gills, but in almost every vertebrate, including humans, they develop instead into the lower jaw, among other structures. They are a definite structure derived from primitive ancestors, not "wrinkles" in the skin nor true gills in the developing human embryo.
So Tamara is absolutely right, it is not true to say that all vertebrate embryos develop
gills. I suppose we'll have to hear how reprehensible and fraudulent it is to say that all vertebrates share these pouches at the exact same step in their embryological development, which develop into gills in fish. Pardon us for mis-educating students that embryonic development is remarkably and significantly similar in all vertebrates. It happens to be true.
