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

> David: 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.-" .. 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."-This is the difference between certainty and speculation. You say "it must have happened". I say, show me. While that may seem like an unfair challenge, that is the exact same challenge I am faced with when I express my faith in God. I am told to prove that he exists. In fact, this is the same hang up DHW has with believing in something without evidence of it that is tangible. -Fore the record, I am NOT saying you are wrong, only that we all must adhere to the same standards. If theist must 'prove' god exists, then evolutionist must 'prove' speciation can, and has, occurred to a degree significant enough to explain the diversity we see today, within the proposed timeline for the history of the earth. I don't care much for double standards.

What is the purpose of living? How about, 'to reduce needless suffering. It seems to me to be a worthy purpose.
