David: Your statement is a given. Tony raised the issue. Simple answer: We don't know the mechanism for speciation.

> Tony: Correction, we don't even know for certain that it occurs. It is assumed.-Of course it occurs: Simple logic: on this Earth, as we know it, life can come only from life to quoe dhw recently. We do not know how life originated, but once it did appear, it progressed from single-celled organisms to us complicated conscious humans. Darwin theory obviously does not tell us how evolution causes speciation, but it must have happened. That is why I believe in theistic evolution. Entirely natural processes don't seem capable of developing the complexity of living organic chemistry in the present human genome. But species do appear in the fossil record. Look at the Cambrian layers, including the new one which is 100,000 years older than the earlier discoveries. Even if you doubt aging techniques, new species appear in an order from ancient single forms to the more complex.
