Joe, this isn't your field. You should have noticed that what they are referring to as 'tail' in either case is anomalous and has nothing to do with the coccyx, which is what your evolutionist folks consider evidence of evolution.
In addition, their identifying it as a 'tail' and then connecting it with some kind of evolutionary scheme is because they first and foremost believe evolution to be true and not because these anomalous structures have anything to do with evidence for it. The fact that they are considered anomalous structures should tell you enough.
Mutations can also give a human six or seven fingers. If the 'tails' in the article are to be considered evidence for evolution, then the six or seven fingers should be considered evidence against it! For they are certainly not homologous with other five digits on other animals!
You can't have it both ways, in other words. It can't be 'evidence' only when it fits and 'anomalous' when it doesn't.
I'm not here basically. I'm going through emails and found a few that added information to this site. The fact that you are willing to argue with a stop sign or even try to direct attention away from it is not something I'm interested in engaging anymore. I've already learned about you and I have no respect for what you attempt to present in terms of the argument for evolution.
