"There is nothing to say that the new species will be *more complex* than the parent species. All that matters is that the individuals of the new species are adapted to the environment they inhabit."

Nothing except the Theory of Evolution. The increasing complexity of new species that is possible in macro-evolution is absolutely required for this "theory" to have credence.

"Speciation has already been observed. And there is overwhelming indirect evidence for the common descent of all life."

As I said, micro-evolution (or speciation) is a theory that obeys the scientific method. It is observable, reproducible, and predictive. Macro-evolution (new species evolving from existing species) is none of these. It violates all principles of the scientific method and should be rejected as unsound. (Screw your indirect evidence. Show me how macro-evolution (NOT SPECIATION) is observable, reproducible, or predictive. Until you can do that, you're not theorizing. You're preaching religion.)

No, it really isn't. All that is required is for the individuals of the new species to be adapted to their present environment.

" As I said, micro-evolution (or speciation)..."

Speciation is not what has been called *micro-evolution*. Speciation is the production of a new species.

" Macro-evolution (new species evolving from existing species)."

Has been observed.

"(Screw your indirect evidence..."

Ah, now your showing your true colors. :)

Here is a link to a good paper expalining how micro evolution can and inevitably DOES lead to macro evolution.
