And these have that complexity. Want a list of some of the metabolic activity seen in the protocells? And they reproduce. See references at end of post.dctalkexp said:Nonsense, because a cell by definition must have enormous metabolic complexity or it will not survive.
Sure is. Not only that, but it has the same membrane potential and action potential of a nerve cell! Cool huh?This is not self organization of a cell.
I have. Spetner makes several mistakes. The most egregious is that he ignores natural selection. He forgets that neither chemistry nor natural selection are chance. We did a thread several months back of the flaws in Spetner's analysis. If you want, start a separate thread and we'll go thru it all again. Just hit "New Topic" on the Forum Screen.Okay, and you read Not by Chance by Lee Spetner and then come back and tell us what fundamental ways that evolution isn't lacking
Good. Now work on Futuyma's Evolutionary Biology.Most of it, I have read about 75% of it online.
No, it's not. "Survival of the fittest" is the sound-bite version of NS. Like all sound bites, it is incomplete.Fine. Natural selection is survival of the fittest.
Nope. Back to reading your Darwin. Summary of Chapter IV of the 1st edition. Darwin explicitly calls natural selection a means of preservation not elimination.Organisms which are not fit for the environment are eliminated.
There you go. Preservation of good designs.An organism may acquire some inheritable trait or character which, in a given environment, gives that organism a greater chance of passing on all of its genes to the next generation (compared with those of its fellows which don't have it). Over succeeding generations that trait or character has a good chance of becoming more widespread in that population.
The only "mistake" is that the DNA was not copied exactly. But that is not a "mistake" for the organism. For the organism it gives a new variation that, as you pointed out, is a better design than the previous one, and thus gives a better chance of surviving the Struggle for Existence. IOW, the environment runs a continuous contest for the best designs. New designs arise from not copying the DNA exactly. Some of those designs are very good and better than any existing one
You are too hung up on the semantics of "mistake". Look at what is really happening and not focus on one word that you emotionally don't like.
When you were learning to talk as a baby, you threw out all kinds of sounds. Most were "mistakes" in that they didn't mean anything in English. But some got positive responses from your parents and others, so you kept them and used them. You then made variations on those sounds and again selected those you got positive responses from. You learned to talk by making mistakes.
I remember two mistakes of one of my daughters -- elphedent and hippopomadus. They were mistakes but were close enough and funny enough that we encouraged her to use them. After a couple of weeks she found a new variation that was identical to the standard pronunciation. Darn!
Biochemist, actually, and I recognize this particular shell game. Creation of more information is a two-step process:But changing pre-existant information which already codes every feature of an organism is not a creative force. It can only change an organism's pre-existant information. I thought you were a biologist?
1. Making more DNA. This is making more text in a book. It is done by making duplicate genes, chromosomes, transposon insertions, etc. That gives you more raw material to work on.
2. Selection. Now, the equations of information are such that selection always creates information. Check out William Dembski (a creationist) in No Free Lunch. He gives the equation -- The amount of information introduced through selection is then -log2(M/N). WHere N is thenumber of possibles and M is the number selected. log2 is logarithm to the base 2. Now, since there are always more individuals born than survive to reproduce, in any generation N is greater than M, thus M/N is a fraction, which means a negative logarithm. With the - sign in front of the logarithm, that converts the negative log to a positive number. Thus, selection must increase information.
It's not the DNA, but the organism that has the design. And natural selection is a creative "force". Doubt it? Then how is it that products designed by natural selection is getting patents?Still, moving around DNA is not a creative force, nor does it explain how you can get rainforests and human beings from the same microscopic cell.

Nice try, but it is me posting the evidence. Not you. All you post is that there is a lack of evidence. Sound just like a militant atheist, you do.Face it, you live on blind faith, with little to no evidence. It really is admirable to see so much faith in you. It's sort of like a child-like faith, many Christians could learn from you.

That was the point. Too bad you missed it.
