Iasion said:Greetings smallaxe,
Firstly,
some general comments -
Thank you for remaining reasonable in your posts,
it is encouraging that you can express your views without descending to insults.
I try to do the same - criticising your claims, not your person
"Try" being the operative word seriously, thank you for your comments and I just hope that all of us can disagree without being disagreeable.
You do not understand this issue fully.
Embryos of different species ARE similar - we can SEE this in photographs.
This DOES teach us something about evolutionary history.
It's a fact, details here:
http://www.talkorigins.org/indexcc/CB/CB701.html
But,
a LONG time ago (a century or more), a chap Haeckel took this idea and exaggerated it into a weird theory - that Ontogeny recapitulates Philogeny (development replays ancestry) - which means that embryos would go thru stages which look like ADULT forms of other species they evolved thru. Haeckel used line drawings, and faked some of them to puff up his theory.
SCIENTISTS checked Haeckel's work and found it was not right,
they also noticed he faked some photos.
Thus,
Haeckel's theory (OrP) was rejected LONG long ago.
But,
the underlieing concept of embryo similarities is true, and always was true,
and
studying these similarities (and differences) has increased our knowledge.
That they appear similar doesn't PROVE that they had a common ancestor. It's evidence, I agree; but based on the "cooking" that Haeckel did, I do not know how much stock I would put in it as evidence for Darwinism. It's all subjective; you look at the similarities and say it's evidence for your view while I look at the differences and say that it's not that strong for your view.
You can see actual embryo photos here :
http://www.pbs.org/wgbh/nova/odyssey/clips/
Please look at these photos smallaxe -
the similarities are obvious,
do you now agree embryos do look similar?
I looked at the photos, I see the similarities and acknowledge the similarities; but just because they look similar doesn't mean they have the same origin any more than just because a pancake looks like the Virgin Mary means that she actually gave birth to Jesus via the incarnation.
But the problem is -
creationists claim that biology still teaches OrP,
when this is
100%
totally
completely
absolutely
180 degrees
FALSE !
Now I know. See, I learn! Where's my cookie?
Yes,
biology DOES still teach that (some) embryos are similar - because they ARE similar
but, no -
biology does NOT teach Haeckel's old OrP theory.
I hear you.
False.
You don't seem to be aware that we have various dating methods -
* Isochron dating,
* radioactivite dating
* luminescence
* fission track
* obsidian hydration
etc.
Such methods do NOT rely at all on fossils.
It is simply UNTRUE to say that dating depends only circularly on fossils -
completely, totally, 100% WRONG.
I did not say that dating depends only on fossils. I know that there are other methods of dating. I know for a fact that fossil dating plays a large part in dating rock formations, and the circular logic behind THAT still stands.
This is false,
as well as confused.
You do not seem to understand the difference between :
* evolution as a fact observed in nature
* the THEORY of evolution we use to try and explain how it works
We SEE evolution -
we observe it in the field and in the lab every day -
we see and work with changing allele frequencies all the time.
Evolution is a FACT because we observe it to be so.
But,
the THEORY of evolution is an attempt to explain how the details actually fit together.
The THEORY of evolution is a vast and complex area of study covering many facets - the details of the theory are always being debated, argued, and changed - like all theories.
So,
it what you said is simply NOT TRUE.
Only people who do not understand the difference say that - usually creationists.
I see...
Words get used a lot, and I think that a large source of contention between creationists and evolutionists occurs because what one person thinks a word means isn't what the other person means.
Evolution as a fact is what I thought was called micro-evolution.
Evolution as a theory is what I thought was called Darwinism and/or macro-evolution (if there is a difference, please tell me what it is).
If I say anything about "evolution" that seems as if I believe it, I'm talking about micro-evolution. So what I understand your above quote to mean is that ypu see micro-evolution in the lab everyday, and you use macro-evo or Darwinism or other theories to predict/theorize where micro-evo is coming from and where it may go.
I'm not saying that that's what you believe, I'm saying that's what I understand your statement above to mean.
Relativity is indeed a theory -
one that is so well supported by the evidence that it is considered one of the great successes in science.
Every test ever done, anywhere, by anyone - SUPPORTS relativity.
NO test ever disagreed with relativity.
The other theories (e.g. Newton) have been TESTED and found NOT as good as Relativity.
Though Newtonian physics does work on a local scale, that's why it's still used in intro physics...
Quantum physics is indeed a (set of related) theories -
one that is so well supported by the evidence that it is considered one of the great successes in science.
Every test ever done, anywhere, by anyone - SUPPORTS Quantum physics.
NO test ever disagreed with Quantum physics.
The other theories (e.g. classical particles) have been TESTED and found NOT as good as Quantum physics.
But what about the clash between Relativity and Quantum Physics that Superstring theory is supposed to resolve? That's a different topic though, i guess...
Evolution is indeed a theory -

Set aside the fact that these sites are run by true believers, and tell me what you think. (Now that i think about it, every website is run by a true believer ANYWAYS...)

Nonsense.
The only "tables turned" is in your inability to accept the evidence -
evolution is as well supported with evidence as relativity.
Except that for relativity, the evidence led to the acceptance of relativity, while for evolution, the evidence was intepreted in view of the already accepted theory of evolution. The basic tenets of evolution were developed and accepted at a time when the complexity of a living organism was not completely understood, and thus as new evidences have come forward, all of that new evidence has been interpreted in the light of "how can this support evolution" instead of "what is this evidence telling us."
It is only religious faith which causes creationists to accept relativity and reject evolution - because they think it disagrees with their faith (of course many Christians have no problem with evolution.)
I know. That is a separate discussion for me and them (and I refer to the theory of evolution, not the fact of evolution.)
Relativity was accepted (against the odds) because it MATCHED what we OBSERVE -
every test,
every time,
every place,
by every person who did the test.
Evolution was accepted (against the odds) because it MATCHED what we OBSERVE -
every test,
every time,
every place,
by every person who did the test.
Against the odds? When Darwin came forward with the theory of evolution, the scientific world jumped right on it because it allowed one to be a full-fledged and honest atheist. Evolution never had a problem being accepted by most people who were not religious back in the day.
Dogs descended from wolves - a different species.
This new species evolved within human history - as a direct result of human activity.
This is prima facie evidence of un-natural selection producing a new SPECIES (not quite the same as natural selection, but an interesting case.)
You deliberately chose a SHORT time frame,
then claimed we have never seen an event that takes a LONG time,
and pretended this proves LONG events can not happen,
even though you had to ignore the direct evidence that showed you wrong -
wolves evolving into dogs within human time frames.
This is an interesting point, but it brings up something that I admit I don't know much about. What is the difference between species that can breed together and species that cannot breed together? Someone earlier said that technically dogs were wolves, I'm just throwing that out there. I wasnt the one who selected the short time frame though; you had taken the process of macro-evolution and then compared it to that of glacial flow.
Also, if dogs evolved from wolves, why do we still have both dogs and wolves? I have always wondered how evolution explains the diversity of species. If one species evolves into another, shouldn't the orginial species become extinct, or all of the orginal species become the new species?
Once again -
your argument boils down to :
" anything that takes longer than a human lifetime cannot happen"
We have never seen a giant sequioa growing to full height from a seed -
therefore, according to YOU, they cannot grow to full height.
We have never seen glacier ice flow from mountain top all the way to the to sea,
therefore, according to YOU, glacier ice CANNOT flow from Mt top all the way to the to sea.
This is obviously a false argument -
why do you keep using it?
I do not use that argument. You built it up from an erroneous interpretation of my argument, and then attributed it to me.
Let's be frank, your posts -
show little knowledge about these subjects,
confuse the most basic terms and concepts,
show no background knowledge of biology or science in general.
But,
you pretend you know better than all the best brains in the world?
When all you have to offer is tired all nonsense apparently lifted straight from AIG which you didn't even bother to check?
You're not trying hard enough
Science depends on EVIDENCE -
you produce no evidence for your claims,
and
you dismiss the evidence which shows you wrong.
Yes,
you are not debating,
you are preaching.
This is a science forum - please don't preach here.
(By which I mean - I look forward to evidence-based discussion. You are, of course, completely free to express your views here.)
Iasion
That comes across to me as "I will preach; you'd better not." I addressed that statement earlier, so I won't address it again here; but the topic here is not science, but Darwin's theory.
