Not quite. Natural selection is the mechanism by which a species optimizes its chance for survival.

Each individual organism strives to live and pass its genetic material on. The most successful
of organisms is the one which passes on the most genetic material (probably living the longest).
So, any advantage in this end that an individual organism has over its brethren will result in the
propagation of its genetic material (and, consequently that advantage).

Yes, sometimes weaker organisms get lucky and pass on their genetic material and sometimes
stronger organisms die early. But, statistically, stronger organisms will survive most frequently
and pass on the most stuff.

Natural selection is merely a description of the mechanism which optimizes the survival of an
individual species.

By the first point - the need to have intelligence - I mean something more than just your 'I can't believe it's not butter' assertion. Scientific models typically operate on a 'simplest-one-is-better' p

By the way, what do you think are the less reasonable parts of Darwin's model?

By the way, what do you think are the less reasonable parts of Darwin's model?

==================================


I agree with Charles Darwin himself when he warned what were the factors which would render his theory less reasonable. He wrote:

"Why then is not every geological formation and every stratum full of such intermediate links? Geology assuredly does not reveal any such finely graduate organic chain, and this, perhaps, is the most obvious and greatest objection which can be urged against my theory"

[On the Origen of Species, Charles Darwin, pg. 280]



So I am only agreeing with Darwin himself that the lack of evidence of a finely graduated organic chain revealing the needed abundant proof of intermediate links, renders the macro-evolution model less reasonable.

So you are saying you agree that 'micro' evolution happens, but 'macro' evolution does not?

I believe that some things can be explained by changes in organisms on a micro level.

Under this heading I would put the changes observed in fruit flies or the breeding of very different kinds of dogs. Also black moths on smoky trees out surviving light colored moths on the same trees.

So can you explain what level of evolution is unacceptable?

How much change is 'too much' for you?

What has been observed is more fit organisms surviving less fit of their same type. What is far less observed is surviving organisms doing so because they became another type of organism.

Perhaps you'd like to pin me down to a line so fine that pointing out a possible exception would prove macro-evolution.

But I think generally speaking you should be able to agree that "evolving" bacteria are still bacteria, and "evolving moths" are still moths. That we have observed. Science is about taking observations.

For too long the public has been duped by zealous evos saying that any change in any organism proves that all life evolved from the first one celled organism.

I'm just borrowing from the old song in Porgy and Bess:

It ain't necessarily so. (It ain't necessarily so).

The things that you liable, to read about in Bio,

It ain't necessarily so.

So if some evolution has been observed, it is I guess by definition undeniable, and so the line you draw is at the point of current observations?

Or is it at and above the point of speciation? (broadly)


[edit1] I suppose you could say that what evolution tries to explain, by 'natural' means, is the various degrees of difference in DNA in animals.

If you wish to believe that there is a supernatural hand in it all, why be so worried about it all; to you, there is no issue; Whatever cannot be explained by natural means is supernaturally brought about. And perhaps also the stuff that that we think is natural is not really natural, it is all guided.

[edit2] I really think there is no clash here at all, and this does not threaten you at all, so I am unsure where your unease comes from.

That's not particularly compelling.
What else do you find less reasonable?

It's on page 213 in my copy.

In the following sentence, he says "The explanation lies, as I believe, in the extreme imperfection of the geological record."

Darwin goes on, over the next several pages, to explain why the geological record is so patchy. Essentially, fossilisation is a rare occurance. The victim must die in particular circumstances, in a specific kind of terrain, during a period of a specific kind of geological activity, before it has a chance of being fossilised.

With this in mind, we should not expect every geological formation and every stratum to be full of such intermediate links.

Regardless, it renders an important potential evidence, not available.

Life is not always fair.

Since that avenue of confirmation is not available to us we need another equally powerful confirming evidence.

With the public at large this has taken the form mostly in the art work of imaginative artists, who have painted what Evolutionists want to see, i.e. ape-men.

I am uncomfortable with your phrasing. Natural selection is not something a species does but rather something that happens to the species.

Artists and now motion picture special effects people are always inundating the public with their creations of missing links.

Programs like NOVA hope that the barrage of wishful thinking images of ape/people will make everyone just say "It must have been so."

Regardless of other reasons at the moment, remember,
Darwin said it would be a problem to his model. I am just agreeing with him.

The key word is 'would'. It would be a problem if it could not be explained. It can. Hence, it is not a problem.
