-
- ]You left out mutation, recombination, and gene flow.
-
- Well, yes and no. Selection and drift are routes to altering allele
- frequency. Gene flow is a redistribution but not an alteration unless
- accompanied by selection. Mutation generates new variation. Recom-
- bination doesn't alter allele frequency; it merely (!) reduces the
- unit of selection from the chromosome to the gene. Symbiosis is much
- more fundamental.

-
- ]A part of the "imperfect design argument" is indeed about God, but
- ]surely that isn't the whole point. "Imperfect design" also shows that
- ]organisms can't start from scratch, they have to build on what's
- ]already there, no? This, to me, points to common ancestry.
-
- By itself this argument doesn't lead to common ancestry; it does argue
- for lines of descent. But this is already evident.
-
- ]>Now consider selection. We contend that selection cannot produce

-
- ]Actually, I think not - organisms aren't [perfectly] adapted to their
- ]environment, just nearly so - or, at least, to an extent so that it
- ]stays alive. I once read somewhere that it's not so much that the
- ]most fit survive*, but that the least fit perish. There's a
- ]difference between these two.
-
- ]* Yes, yes, I know evolution isn't 'the survival of the fittest'.
-
- It all depends on how you define "fittest". Actually, organisms are
- well adapted to their environments, given the constraints.
-

-
- ]*Can*, but do they always? I think not.
-
- Apparently adaptation to changes in the chemical environment can happen
- quite rapidly; this makes sense -- the adaptations are at the cellular
- level. In the normal course of things a change in the environment is
- met by moving or death -- when the environment changes other species
- which are already adapted to the new environment move in.
-
- [Hint: What I'm saying is reasonably sound, but I'm cheating.]
-
- ]>Symbiosis reduces to selection.
-
- ]I've never heard symbiosis is a mechanism of evolution - it's a
- ]result, no?
-
- Margulis thinks it is, e.g. the Eukaryotic cell.
-

- ]signifigance.
-
- ]But neutral mutations change DNA, no? Assuming it changes a gene in a

- ]at the same gene might produce an effect. In that sense, I would say
- ]that *all* neutral mutations don't have no significance (though most
- ]do). (Yikes, is that correct English?)
-
- Your argument doesn't appear to lead anywhere -- the further mutation
- must be good, bad, or neutral. The same arguments apply to it.
-
- ]>Advantageous mutations of phenotypic signifigance have no
- ]>signifigant probability of occuring because they must be coordinated
- ]>changes. In other words it does not suffice to change a single gene;
- ]>several must be changed at once.
-
- ]Is this so? There certainly are some cases that needs a change in
- ]many genes, but again I don't think that's true in *all* cases.
-
- Actually you can distinguish between changes in the cellular chemistry
- and those that have structural impact. The argument being made is
- against those have structureal consequences. For example, suppose that
- the change is run faster. This type of change has several components,
- e.g. change in leg formation and increased capacity to use oxygen.
-
- ]> The odds against multiple, simulataneous changes
- ]>are very long indeed.
-
- ]Agreed.
-
- ]>In short,
-
- ]Again you left out recombination.
-
- And rightly so.
-
- ]> we atheistic creationists take the view that evolution as a
- ]>purported historical fact has not been established, and that the
- ]>purported
- ]>mechanisms cannot account for the results that are claimed for them.
-
- ]You claim 'evolution as a purported historical fact' (what does this
- ]mean? Either evolution occurs or it doesn't) has not been established.
- ]Well, I claim that your claim that the purported mechanisms *cannot*
- ]account for the results has also not been established.
-
- You have to take into account that there are distinct meanings of
- evolution floating around here. The first is the thesis of common
- descent, which is a statement about historical fact. The second is
- the concept of evolution as changes in genetic constitution. Now
- it is conceivable that you could have evolution in the second sense
- without common descent or indeed any signifigant phenotypic changes
- in a given descent line over time. Before you make a statement that
- evolution occurs or it doesn't, you have to make clear whether you
- are talking history, genetics, or their presumed connection.
-

-
- ]Though I just did it, I must again point out that you haven't

-
- You want a complete theoretical tome in a usenet posting? Give me

- to rope with which you could hang me; said rope lies there undisturbed.
- "Didn't", "Did so" isn't a very productive line of argument.

-
- ]1. Does anybody except Hoyle and Gold themselves believe in this

-
- "Did" is the operative term; the answer is yes. Steady state and
- Big bang were the two major contending cosmological theories. Big
- bang won out because of the evidence supported it rather than steady
- state. However both were in contention.
-
- ]2. Because a scientist says something, it doesn't mean it's science.
-
- This is unworthy of you.
-
- ]3. Creation of hydrogen is to my mind a whole lot more likely than
- ]creation of genetic information.
-
- Offhand, it would seem so. However this is not a very good argument
- in its own right; "likely" is really a statement about one's mode
- of thinking.

- ]was 'spontaneous creation of genetic information'?
-
- Probably not -- a fact in which I take great pride. Do you realize
- how difficult it is to create *original* crackpot science?
-
- ]Unless, of course,
- ]by 'spontaneous creation' you mean forming molecules without
- ]intelligent intervention, and by 'genetic' anything that replicates.
-
- Altering, not forming; otherwise yes. We want to pay due deference
- to the conservation of matter and the laws of thermodynamics.

-

- ]should I?" Do you consider alternatives for, say, the General Theory
- ]of Relativity?
-
- Well, I don't, because I'm not a professional physicist. However there
- are professional physicists that do. Dicke, for example.
-
- More to the point -- how can you know whether Evolution is good science
- if you are not willing to consider how it might be falsified and what
- the consequences of falsification might be?
-
- ]==================
-
- ]Well, one more thing. I dropped this thread way back
- ]<whenever-it-was> because I got bored. However, I saved your original
- ]post and decided to read it carefully later. Well, now I did - one
- ]reason for it is that now I got bored with Kalki's stuff.
-
- -------------------
-
- To tell the truth, every once in a while I argue as a creationist
- [I draw the line at Holdenism] because the average creationist is so
- incompetent (besides being grossly outnumbered) that I feel they need
- some help.
-
- Kalki could be interesting if he would stick to expounding Vedic
- philosophy -- it's always worthwhile listening to someone with a
- different world view.
