Yet another evolutionary icon has fallen to the data.
Darwin-defenders like Karl Giberson have used the rare phenomenon of babies born with supposed “tails” as evidence for common descent.
Prominent medical researchers on the “human tail” now see it as “a disturbance in the development of the embryo” not “a regression in the evolutionary process.”
The little we know of early religion was not predicted by naturalist theses — and has not confirmed any of them.
Karl Giberson wants us to think that true tails are some kind of a regression to an earlier form.
