The researchers also found that rapid bursts of evolution appear to have occurred in many more plants and fungi than animals. Genetic alterations such as hybridization or changes in ploidy could allow rapid speciation, Pagel said, and these mechanisms are much more common in plants and fungi than in animals.
"Their result is pretty interesting, particularly the fact that they got so much more from plants and fungi than they did from animals, which I don't think most people would expect," Erwin told The Scientist.
Reckon pollination is mostly to blame?

While digging irrigation ponds at the family farm, we used to dig up or uncover petrified wood along with arrowheads.

I've been watching mythbusters and on that "revolution in Iran" thread...
Do you have a link for your guy who modeled fitness landscapes?
That'd be like the "ultimate" in cool...
...Besides, it'd be fun to do sensitivity analysis on it, or to debug his code ;-)
Cheers!

Then when you have separated, via line and time, it becomes pretty obvious what changes have occurred, and yes, they have become completely different species. Or, they were always different species of animals unrelated except for where they lived.

Oh, so the courses I took in college which presented the "evidence" for the TOE wasn't good enough! I need to receive and "education" from some toad on the internet.

Will Wright is featured in one of the articles of the August 2006 edition of Discover Magazine
I believe that a derivative of this is one of the core algorithms in the game "Spore", which is coming out next year.

Many facts have been added, and details changed, in the theory of evolution since you (and I) were in school. But the theory itself has only been supported; the additional details and facts have expanded the theory, not contradicted it. The theory is currently stronger than ever.

"If Creationism was true, we would have to believe that modern humans walked with Dinosaurs and swam with the Trilobites, right? I would have to believe that all the animal species that exist today, existed at the creation of the Earth, right? I never made the claim of being a "creationist". At least not of those who proclaim the Earth is only 6000 years old, and that all animal species (including humans) "became" at the same time. My question doesn't have anything to do with whether or not living organisms "evolved". I have no problem with that tenent of TOE. I just don't see where a specific animal species changed such that it became something entirely different (which is what many evos propose).

Hey how is your son doing? That is much more important right now.
In 1971 I was enlisting for combat arms mos in the US Army but backed out at the last minute, so now I am a 'wannabe VietVet'. In 1971 and '72 the conflict had shifted more into Laos and Cambodia, more Laos IIRC. This was not widely reported then, most likely that is where I would have ended up.
This is a totally different war they are fighting over in Iraq than we would have back in the 70's. That is obvious of course. We did not have near the personal protections, or the powers of some of the new weaponry available to us, but we were not faced with the humongous IED in a urban environment either.
But back to the debate.That some men believe and assert as a reality that all men have come from some ephemeral ape ancestor really means nothing to me (nor does it bother me) save for where to from that concept that some among them want to lead.
I dont get the 'janitor' denigration either, unless it is the inference that academic recognition is some sort of value judgment on a mans life and contribution to the world.
That might be an interesting topic to research.

When one looks at it Creationism falls apart from a scientific standpoint. There just isn't any evidence that all species were created at once, or even within a hundred million years of each other. If we were to consider just for one moment that God did indeed "create" all life on Earth, why would anyone think that He had to have "created" all life forms at the same time? Would it not be possible that God started off with those earlier life forms, and then over various periods of time (separated by lengthy periods) He "created" different life forms? What you call "explanations" are merely guesses of what happened which fit the "evidence" as humans understand the "evidence" Guesses can never be proof as any scientist worth their degree will attest.

I honestly don't know how my son is doing now. If you notice my new tagline You'll see where he's located. There was a post on FR regarding the 10th Mountain Division tonight, and where their AO now is. We have not heard from him since the email he sent last Tuesday morning. The new AO for the 10th must not be a very safe place, because my son told his brother not to let my wife and I know where he was moving to in a phone call he made about 12 days ago.
I served in the Air Force in the mid to late 70's, and was stationed at Minot AFB in a Security Police Squadron. Same job my dad did during the Korean conflict (though he was never deployed to Korea). My brother was an Army Ranger right at the end of Viet Nam, but also was not deployed to the war. Right now we have my son and my nephew (my brother's son) in Iraq. A close friend's daughter is also in Iraq. Our family has served in the U.S. military since the Revolutionary War, and we've had a family member in a war zone in almost every war/conflict since (two uncles served during Korea and Viet Nam).
As for the debate - it has denigrated into a insult fest from what I can see.
Thanks for asking about my son. I'll let you know when we next hear from him.

What you call "explanations" are merely guesses of what happened which fit the "evidence" as humans understand the "evidence" Guesses can never be proof as any scientist worth their degree will attest. Guesses.... all the work that Paleontologists have done is all just guesses. Just a wave of your hand simply dismisses it.
Ok have a good night.

Hmmmm. When I read my Bible it
specifically says that things were created in a certain order.
Starting with the chaos of the big bang
Moving on to the point where light came into being
Then solid matter condensed from the 'liquid' plasma.
The solids and fluids were gathered and separated
Plants came into being
Then swimming creatures
Then (dinosaurs which became) birds
Then mammals
And finally, that Johnny come lately, Man
Pretty much the same sequence that Physics and TOE have.
The main difference between the stories the Bible and Modern Science tell is the timescale. I don't know how long one of God's days is, but I do note that the Seventh Day doesn't end with "And the evening and the morning were the nth day" like days 1-6.
I assert that we are still in the Seventh Day as the Bible never says it ended...
And the Bible deals with what and why, while Modern Science deals with what and how.

I really don't know why I keep getting accused of "dismissing" the work of all these scientists when I'm just asking questions (and not getting any answers). If I say I get that some animals have shown "evidence" of micro-changes, I'm then told I'm dismissing "evidence" by waiving my hand.
