Acutally, most random mutation is neutral or slightly deleterious.
Better stated, most random mutations are slightly deleterious, while some are neutral. Of course this calls for a whole other thread to debate this, full of presuppositions on both sides (such as the level of junk DNA, of constraint, etc). I actually believe Futuyma’s graph is pretty close to reality:

....so such a black and white assessment does an injustice to the over 100 years of genetics research that has been done...even my listing is only the tip of the iceberg
You’ve been erecting a fair share of strawmen lately. I have previously stated a range of harmful through neutral, which is not a black & white assessment. I am willing to accept Futyma’s graph, at least for debating purposes, are you?

How have dog breeds "lost" genetic information? The only decrease is at the population level i.e. a bottleneck reduces variation among individuals.
I agree completely.
quote:
A chihuahua has just as many base pairs in its genome as a wolf
So? It is also well established that Chihuahuas have a much greater range of health problems. Why? Loss of genetic information. Too many deleterious recessives pairing up because the original dominant is long gone (but still present in the dog kind, like the much superior Malamute
). FOr some of thos who may still be missing the point, here are two more clues: Think Arkansas, or think West Virginia.
But I realize to you guys, this is evolution in action!
The rednecks in Deliverence were well on their way to a new and improved species of human!
quote:
genetic variation than their "parent kind"...I guess they are accumulating genetic information
We have hashed this out before, so what is the point doing it again? Increased genetic variation does not = increased genetic information. The only people who think this have no training in information science (like all the goofs here who say they would rather have a lifelong, and in many cases life-threatening blood disease instead of risking malaria that is typically survivable with full recovery; I will always marvel at those daring enough to admit believing disease is an increase in genetic variation, and therefore an increase in genetic information. One PhD on Yahoo once claimed that cancer was mud-to-man evolution in action! And you guys wonder why and object when creationists state that mud-to-man evolution is a religious faith?).

transosons. tranposon
Actually they are called transposons
Those were typos (I was in a hurry). If you merge them (apply crossover & recombination), you get transposon.

THis fits quite well within a creation model.
--------------------------------------------------------------------------------
What creation model would that be...the I don't know what a transposon is so therefore goddidit?..lots of things are apparently consistent with this "model"
Another strawman? I guess with Halloween coming up you are just getting in some good practice?
The point is that transposons have all the earmarkings of intelligent design. Evolution can’t explain how such an elaborate mutation system that can effectively and safely insert sequences across the entire genome arose via random DNA copy mistakes and blind selection!
