When it comes to theories, I read a lot in your link (among others) about environmental changes causing biological changes. However, what I didn't read was inclusion that many changes occur without need, or that needed changes don't occur. Thus, maintaining the "theory" status of evolution as an answer.
As for Intelligent Design, show me another planet of similar age and circumstance that has life, or (even better) an older planet that had life. Any other life anywhere. They came close with the Mars asteroid, but found out that it wasn't so true. So, there's a theory that states an Intelligent Designer chose this planet, created life (no one's been able to come up with how life formed, let alone how sea weed and mosquitoes and octopus and humans all came from that one cell), and this is it. No other planet has life that we've been able to ascertain (hypothesis to theory).
We're slipping back off the same page with regard to the meaning of the word "theory" I'm talking about theory as in, backed with repeatable observation and experimentation.
Evolution is the change in information contained within genes, over time. The information encoded within genes does indeed change over time. That is a fact. We know this.
"Need" has nothing to do with evolution. Nothing in evolutionary theory says there is a purposeful effort behind the changes in genes. Frogs don't say, alright guys, the weather is getting colder we need to make a few changes... There are (in all organisms!) changes/mutations that are useless, harmful, beneficial, and every gradient between.
Oh come on now "show me another plaet..."
If I could do that...
If I understand correctly, Intelligent design is based off the close observation of a single planet over the last how many years? I keep seeing 6000 thrown about as the age of the world according to the bible.
So, 1 planet observed for 6000 years (with the ability to ACTUALLY observe other planets considerably shorter than that) and ID'ers jump to the conclusion that there is no life anywhere else in the ENTIRE universe.
Quick google search turns up 10^22 stars in the universe. If only ONE star in a MILLION has planets in it's orbit, that's 10^16 star systems with planets, or 10,000,000,000,000,000 systems. How many planets in each system?
And all of it pronounced dead as a door nail before we even check for a pulse???
It gets even more uncomfortable when you find things like this...
