>>The accelerated evolution of these genes in the human lineage was apparently driven by strong selection. In the ancestors of humans, having bigger and more complex brains appears to have carried a particularly large advantage, much more so than for other mammals.<<

Everyone knows that men prefer to "mate" with women with big brains.

Wait. Do I have that right. Are brains a physical attribute? Maybe it wasn't brains I was thinking of. But they ARE big.

And everyone knows that even in caveman days, being named Poindexter was a real turn-on to the down-to-earth females of the day. They would have none of that brawn over brains stuff.

It was a nightmare for the tough guys though. And, living in such a genteel society (at least we all know it was in THOSE days), they couldn't just pound poindexter. They had to defeat him in a battle of wits - a battle they would almost certainly lose.

So much for natural selection...

Because I know that God spoke us into exsistance, not used evolution, its as simple as that.

Having done that he then filled the world/universe with evidence that that was not what he had done. What curious behaviour.

...We've done a rough calculation that the evolution of the human brain probably involves hundreds if not thousands of mutations in perhaps hundreds or thousands of genes — and even that is a conservative estimate.”

It is nothing short of spectacular that so many mutations in so many genes were acquired during the mere 20-25 million years of time in the evolutionary lineage leading to humans, according to Lahn. This means that selection has worked “extra-hard” during human evolution to create the powerful brain that exists in humans.

Natural selection worked “extra-hard”? How does natural selection ‘work hard’?

Watch out, people. Remember this primary fact--under natural conditions, 'selection', is always AGAINST something. It is never FOR anything. There is no such thing as "selection for", no matter how many times darwinists, or anyone, says it.

"Natural Selection", were it to have a proper, non-anthropomorphic name, would simply, and accurately,(OK, why hold back-- truthfully) be called , "The Accidental Process of Elimination".

I am sure the bacteria and the earthworms will be surprised to hear that there are two genders of everything.

BTW, when are you going to tell us what the theory of evolution says?

I believe that the All Powerful God created us. I just don't claim to know the specifics of how God did it. So God spoke, and evolution started. Its just as possible He created us the way you believe. Everything is possible with God, even evolution.

Breeding explains evolution because it's two different words for the same thing, except that one is done intentionally by man, and the other is done randomly in nature.

In nature, environmental conditions place selective pressure on creatures and favor some over others, thereby causing the more favored specimens to live longer and be able to disseminate their genes more effectively, which over time causes the species to change. In domestic animals, humans choose which traits are to be passed along to future generations, which also causes the species to change, albeit much faster that in nature since it's intelligently guided rather than random.

"What I belive is that God gave the canine all the genes to make the diffrent breeds..."

Couldn't that also be true in nature, and environmental pressures doing the selecting? If it's true for dogs (and cats and cows and pigs and carrots), shouldn't it be true for all living things?

This is a puzzling comment for a scientific article:

"This means that selection has worked “extra-hard” during human evolution to create the powerful brain that exists in humans."

That should come as quite a shock to the Pope since he is on record as saying that evolution is compatible with Scripture. Perhaps, you are talking about treating Genesis as a literal account without any poetic or symbolic language? If that's the case, then, given the big bang theory and general relativity, it's still possible that God created everything in six literal days using the big bang cosmology. It just requires the realization that when God wrote the Genesis story His reference frame is not the same as our reference frame now. An observer in a high gravitational field (such as what existed in the first moments after the big bang) will measure a much shorter duration for a given event than an observer in a reference frame with a lower gravitational field. For example, God might very well have measured a six day period for the development of the universe and the evolution of life on earth, while to us it appeared that this process took 10-15 billion years.

"Why is it such a stretch of the imagination to suppose that such a thing can happen randomly in nature?"

While animals such as the poodle could evolve randomly, you have to admit that while wildly different from your average mutt, the poodle is not a different species from that mutt. To prove evolution, you must show evidence of an entirely new species being created by natural selection.

For those of you who believe in the THEORY of evolution, you may learn a few things by visiting

You can listen every day to their radio broadcasts on creation and intelligent design. I've always loved their short spots on the radio.

Curious language. I take it they mean that the selection pressure for larger and more complex brain was intense.

How does natural selection ‘work extra hard’?

One thing is for certain, it sure doesn't belong to the teacher's union.

The ultimate origin of life is not addressed by the theory of evolution. Logically, God could have created the universe and life and used evolution as his mechanism for producing the various species that exist, willl exist and have existed.

If you disagree take that up with the Bible and the BJU school books.

The Bible does not contradict the theory of evolution. The Pope understands that, for example. As for Bob Jones University school books, they're hardly a credible source when it comes to science.

So explain that over millions of years we are THE ONLY intelligent being on the planet (aside from cats ;) ) I would think that some animal over the past years hasn't come even close to developing intelligance.

Hey, you just prompted a disproof of evolution into my head, fantastic. "If ToE is true, then why haven't we evolved telepathy, which would give us a really cool advantage"

Who has the advantage, the violent psychopath who constantly resorts to force to get his way, thereby making enemies of everyone he encounters, or the guy who is able to build alliances with other males to get rid of the troublemakers?

You're assuming that being violent and aggressive is a positive trait.

Maybe we will in the future. Maybe we just haven't evolved that far. Or maybe, since I believe God guides it, He knows not to push us in that direction because of consequences that would occur.

HMMM ... ever notice how aliens (the space kind) have such big heads and presumably big brains? Evolution @#$%&! Anyone with half-a-brain should know that God drove a flying saucer!

Because (contrary to a common human opinion both amongst evos and creatos that intelligence is the ultimate pinnacle of evolutionary expression) in general high intelligence is not a particularly useful adaption. Sure we are numerous and dominate our planet for the last few-thousand years. The Sauropods managed that for 100 million years.
