(But they made such a good example that … )
Further to “Vestigial” whale, dolphin hip bones actually needed for, um, reproduction (Lots of vestigial organs prove that Darwinian evolution is true, but not finding any also proves it true. Sign of a strong theory.):
David A. DeWitt kindly writes to say,
This is not really new. I have material from several years ago that showed that the pelvic bones were attachment sites for muscles involved in copulation. Pythons also use their ‘pelvic girdle’ during mating. The males use them to rub a particular patch of scales on the female which help them to become receptive to the male.
The only new aspect to this is the analysis of 3D shapes and the correlations to testes size which makes an evolutionary story. These bones never were vestigial and it has been known for a long time.
I am convinced that Darwinists ignored the known function of the whale pelvic bones until they had a Darwinian ‘just so’ story to link it too. Let’s see how long it takes for this to show up in biology textbooks since they now discuss them as ‘vestigial’ and evidence for evolution.
Note: Some have written to say that an appendage can be vestigial but still functional. Actually, if it assists reproduction, it may be critical, but we won’t quibble.
The problem is that the qualification (vestigial but functional) takes all the punch out of the claim that vestigial organs demonstrate explicitly unguided (Darwinian) evolution. If evolution were guided or designed, we might expect that some parts greatly change their function as a response to changed circumstances, as here.
Evidence for Darwinian evolution would be vestigial parts that are actually useless but not naturally selected out because they do not compromise survival. Perhaps discussion should focus on those parts, if anyone can identify them.
