> dhw: The fact that uses have changed does not seem to me to denote pre-planning. “Unused” may be part of the definition of exaptations that you prefer, but it is clearly impossible to prove that any organ was not used at the time when it came into existence.-You refuse to look at the viewpoint that the vocal tract was never used in the way for which it was designed over millennia until modern language appeared. 
Of course it was used in a simpler way when the tract itself was simpler. If H. sapiens arrived 250,000 years ago and spent the next 200,000 years learning how to use it for modern language, this fits my theory, and it fits the current interpretation of language development, one of the major items that makes us very unique

> dhw: I think the above also covers Tony's claim that “Humans were planned and designed to be able to communicate, and all the necessary morphological differences that were needed for that to happen were planned into our design.” If you begin with the premise that God planned humans, then the rest of your argument follows. It is your basic premise that I am challenging. David is grateful for your support, but unlike you has to face the insoluble problem that the anthropocentric theory does not fit in with the history of evolution.-Only under your interpretation is it insoluble.
