Author | Topic: Definition of Evolution | |||||||||||||||||||||||||||||||||||||||||
Ihategod Member (Idle past 6060 days) Posts: 235 Joined: |
I am unhappy with the results of the last thread for the definition of evolution. Which seemed to be from RAZD (Source):
Evolution is the change in hereditary traits within populations of species over time, and these theories explain different mechanisms and processes that occur. These theories also explain the existing evidence known from genetics, lab and field studies and the fossil record. One could say that the overall theory of evolution is that evolution happens, has happened and will continue to happen. I don't think that it is fair to Creationists that this be let off the hook so easily. I think the definition should be changed to: Evolution is observable change(s) in all living systems limited to the observed time frame. Mechanisms should not be classified within evolution. It should be acknowledged that theoretical science is separate from theological musings, and should not be coupled within a standard of a definition. Rebuttals?

He can help allay this suspicion by answering a direct question: Assuming that we do see evolutionary processes happening now, what is to prevent them from having happened in the past? Rrhain Thank you for your submission to Science. Your paper was reviewed by a jury of seventh graders so that they could look for balance and to allow them to make up their own minds. We are sorry to say that they found your paper "bogus," specifically describing the section on the laboratory work "boring." We regret that we will be unable to publish your work at this time.

If I understand you rightly, you are saying that it is unscientific to belief evolutionary change took place before people observed it.
This isn't actually true. This belief can be scientific. Whether observed first hand or not, there is still a wealth of evidence from beyond a human timeframe (paleontology in conjunction with geology for example) that is best explained using an evolutionary hypothesis. You say you are unhappy with mechanisms, but why? One reason you might object is because once a mechanism is in place, then for what you say to be true, you would require a second 'brake' mechanism to be in place to prevent continued change by natural selection. By itself, this isn't a very persuasive argument against evolutionary mechanisms. So putting this ad hoc objection aside, why don't you think mechanisms should be classified within evolution?

It really helps moderators figure out if a topic is disintegrating because of general misbehavior versus someone in particular if the originally non-misbehaving members kept it that way. When everyone is prickly and argumentative and off-topic and personal then it's just too difficult to tell. We have neither infinite time to untie the Gordian knot, nor the wisdom of Solomon. There used to be a comedian who presented his ideas for a better world, and one of them was to arm everyone on the highway with little rubber dart guns. Every time you see a driver doing something stupid, you fire a little dart at his car. When a state trooper sees someone driving down the highway with a bunch of darts all over his car he pulls him over for being an idiot. Please make it easy to tell you apart from the idiots. Source |

Evolution is observable change(s) in all living systems limited to the observed time frame. Can we drop the 'living systems' and stick with 'populations'? What I'd like to know then is what do we call the 'unobservable changes in populations that occur outside an observed time frame'?
Mechanisms should not be classified within evolution. No - mechanisms should be the realm of theories. Events should just be described as they happen and we should develop theories to explain them as best we can.
It should be acknowledged that theoretical science is separate from theological musings, and should not be coupled within a standard of a definition. Consider it acknowledged. I'm not sure why you needed that - I thought it was obvious!

Firstly, my body is a living system, but nobody would argue that my getting up to go to the bathroom is evolution (though it is an observable change). Perhaps 'living species' or something would be more accurate? I also don't know about the last bit. If you're already observing the change, can't you just assume the time frame was observed too? What do you mean "You can't prove a negative"? Have you searched the whole universe for proofs of a negative statement? No? How do you know that they don't exist then?!

Close. I want and meant to state that observable change shouldn't be coupled with unobserved pretenses. This should be separate from the actual definition of evolution. I don't know how many tabs have been kept on actual populations in the world and for how long. Not to long probably for either YEC or old earthers. I wouldn't dream of confining the laws of physical nature to the observed as I doubt that evolution is a law of nature. If we adopted a catastrophistic ideology, then it's possible that life might not have varied greatly as was there was zero neccesity. Uniformitarianism commits itself to evolution as a foundational philosophy, and people will argue that it is validated by geology. However, even if this were true, the implications of major change are not noted in the overwhelming majority of the fossil record. Also, if the definition on evolution were loosened, these things would and must be inferred.
Assuming that we do see evolutionary processes happening now, what is to prevent them from having happened in the past? A perfect pre-flood world.

You say you are unhappy with mechanisms, but why? Because, then evolution would be a loaded definition. A definition of a car gives an overview of the machine, not the origins of design nor does it explain any facets of a combustible gasoline engine. I'll be happy to change evolution to exactly what you really want it to be. Evolution- a change in species via genetic mutations and natural selection over Billions of years.As long as we can officially change observable change in genetics and physicality to Variations within a kind. This supplicates both of our religions.

Fine by me. We call "unobservable changes in populations that occur outside an observed time frame" -speculations or fantasy. I haven't personally witnessed any type of "evolution" in or outside a laboratory. I remember something about experiments on a fruit fly. They never got anything else other than a fly.http://www.hartnell.cc.ca.us/faculty/jhodin/superfly.htm This guy pretty much makes some wild claims against evolution, maybe he is unaware? His defense of the fruit fly is disturbing.

We call "unobservable changes in populations that occur outside an observed time frame" -speculations or fantasy. If evolution is change in populations over time - observability of this phenomenon doesn't change the phenomenon so why should we give it a different name? I understand you argument is that we cannot be sure of events that happened before direct observation - but that should have no bearing on the name we give something - otherwise you'd have to call Creation 'fantasy' since that was also inherently unobservable. This doesn't really make much sense - why not stick to one word to describe one phenomenon?

So, you're theory is that what happened in the past was not directly observed by us and therefore could have been different than it is now.
Okay, then here's my theory: The world was created exactly as it, including these forums along with my previous posts, at exactly 10:33 am PST on what we call July 22nd, 2007. Everything was created, including our memories, in order to give us the appearence of it being older or that we had been around longer. Before 10:33am everything was "different". Good luck disproving me.
A perfect pre-flood world. This is an incredibly short sentence and you've still managed to get it wrong. You hypothesize that there was a different world "pre-flood" however, since we know there was no flood, this hypothesis falls flat on it's face.

This doesn't really make much sense - why not stick to one word to describe one phenomenon? To you, creation is fantasy. To me, common descent is fantasy.Fantasy Definition & Meaning - Merriam-Webster The fact that origins is unobserved yet, given evidence to support each hypothesis makes it speculative. Evolution claims of supporting evidence that is at best loosely related, ie geology however, doesn't really support the macro model of development.I would gladly stick to evolution without the common descent inference attached.

Good luck disproving me. I could use the same argument to further my philosophy, as I did in fact suggest.
So, you're theory is that what happened in the past was not directly observed by us and therefore could have been different than it is now. Yes, It would be foolish to suggest the same atmospheric and environmental conditions existed the same at any given point in the unwritten historical record. This is the problem with uniformitarainism.
You hypothesize that there was a different world "pre-flood" however, since we know there was no flood, this hypothesis falls flat on it's face. I don't think the flood can be easily written off like your peremptory comment. And this is off topic. please see the rules section to better understand.
