Still Napping

Quote from Vi3t-X
I'm not at all religious, but the reason why evolution is still only a theory is because everything would have had to evolve out of nothing. If the cell is the most basic unit of life, and evolution is the change over time in a selection of organisms, the cell and its contents could not have been evolved because there were no populations to begin with. To answer that life was created with intelligent intervention is also only theoretical because of the same reasons.

...my wording sucks.

This is abiogenesis. Not evolution. I think we need some clarification.

Abiogenesis: a hypothetical organic phenomenon by which living organisms are created from nonliving matter.

Theory of Evolution: a scientific theory of the origin of species of plants and animals.


The important note is that abiogenesis explains how life first came to be, while the theory of evolution explains the diversity of life. No, you may not argue these points. These are not points that can be argued, they are the meanings and definitions of words. So no, I'm not entering this "discussion".

Please stay on topic. If you wish to start another thread about abiogenesis, then do that, but do not clutter up the discussion here about it.

Yes, but the theory of evolution, in this case being used as proof against creation, requires that abiogenesis is possible. The argument is extremely relevant.
You are doing something that many atheists do.
Once someone brings up a good point, you change the subject.
It's just an endless cycle of hiding behind different theories and claiming the argument is irrelevant because it relates to a different branch of science.
The truth is, every branch of science depends on the others to be proven or disproven. Instead, I'll claim that chemistry has nothing to do with biology, and that gravity has nothing to do with physics.

Creationist "I don't think evolution is true, there must be a god to create everything"
Atheist "There could be a God without evolution, I'm not saying there isn't. Your argument is irrelevant."
Creationist "So you are saying there is a God, are you not?"
Atheist "No There is no God. You are delusional. Evolution proves that there is no God."

I'm not going to bother making yet another Creation vs. Evolution Thread.
Even if I did, the minute Evolution was mentioned you would say that the argument needs to be made in the Evolution thread and is therefore irrelivant.

It actually doesn't. Even if God made the universe and then created early life, evolution could still be viable.

Creation relies on evolution not being true, but evolution doesn't rely on creation not being true. There's just no evidence that it is.

May 21 2011, 11:49 pm ubermctastic Post #267



Creation doesn't rely in evolution not being true. But in this case you are trying to disprove creation. So really the argument would be between creation vs abiogenesis. I'm just saying that creating another topic is unnecessary because creation deals with all of these theories, not just one. You seemed Perfectly fine with a discussion about magnetic shifting on a non related topic, so I think it's only fair that abiogenesis be discussed here to.

The theory of evolution does not require abiogenesis to be possible. God could have very well created the first lifeforms, and then evolution would have taken over.

Of course, God would have had to create bacteria some 3 billion years ago, not full-human beings.

People shouldn't have to 'believe' evolution as if on faith. All the evidence is there, go have a look for it yourself. The concept isn't even that complicated. Stronger things survive, weaker things die, organisms change overtime and pass these changes on. You except those things, boom, you've got evolution.




May 22 2011, 12:51 am ubermctastic Post #269



Don't try to pretend you don't just want us to agree with evolution so that you can say the Bible is false.
There would be no reason to discuss it if that was not the intention.

Yes evoultion does happen, no it does not interfere with my belief in God.

Honestly one of the problems I have with evolution is the assumption that genes are just going to randomly change. I haven't seen any proof of this in anything other than bacteria and viruses, and they don't grow new strands of DNA out of nowhere. You also never see bacteria evolve into multicellular organisms. The only two examples of losing or gaining chromosomes I've seen are downs syndome, which isn't something I would consider to be making a more "evolved" person, and Mules, which are a hybrid between horses and donkeys. Neither of these is proof of evolution.

Natural selection works when it comes to getting rid of bad combinations of chromosomes, but it doesn't really work when it comes to mutated forms of an animal. How would this mutated animal with extra chromosomes multiply? asexual reproduction?

You are thinking of it in 'too large' of steps. Evolution is much smaller steps. Instead of an entire extra chromosome creating some mutated animal it is.
Due to the way gamete cells split and recombine during conception each human has entirely unique DNA. The stronger ones survive to reproduce the weaker ones don't.

Our bodies detects a niche and it does its best to fill this niche. Mutation is partially luck and partially because our body knows its what we need to survive.

I know that both ideals can coexist and i wasn't stating that one disproves the other.

No, there is nothing intelligent about mutation it is completely random. Natural selection decides if a mutation is more or less beneficial to survival.




May 22 2011, 9:31 pm Tempz Post #273



Mutation is intelligent, for e.g. people who are bitten a certain amount of times become immune to a certain poison. Another one is when people are injected with a little bit of the disease to build an immunity.

For the third time in this thread: evolution has no intelligence and no plan. Giving is one is a foolish misrepresentation.


Our bodies survive best in a niche because the people most fit to survive in that niche are the ones most likely to reproduce.

Yes, although I think you're over-stating natural selection here, almost giving it an agency.

It doesn't 'decide' anything - that is indeed implying some sort of intelligence or discrimination is involved; I know that isn't your intention, but someone else reading it can easily infer that.

Further more, 99.9999% of mutations will have no impact on the survivability of the host organism at all. Also it may take multiple different mutations, all working together in a similar direction, before the survivability is impacted - we could build up mutations over 1000 generations for a specific trait, but it takes 1 more mutation until suddenly the organism itself is visibly different. This in itself could almost be evidence of "macro evolution" that people keep harping on about. Similarly, there can be a bunch of mutations that serve no benefit or malus in the creature's current environment, but when the environment suddenly changes, the stored up mutations end up being beneficial - this is essentially what happens with antibiotic resistance in diseases.

In fact we see this sort of behaviour with recessive genes anyway - two parents can each carry dominant and recessive genes for a particular trait, but only 1/4 of their offspring will express the recessive gene. Again, you could call this an example of "macro evolution" that apparently doesn't happen, when the descendent can look dramatically different from it's parents. Just repeat that same process 1000 times and the distant ancestor may look very different from the modern progeny, and in fact be incompatible genetically because of the subsequent build up of mutations.

A fine addendum. I agree completely.

Yes the link on Lamarckism provides a nice account of the mistake you just made. When a person is bitten X times and becomes immune to X poison that trait is NOT passed on. I remember learning about this in high school.

Quote from CecilSunkure
I do agree it is possible that over millions of years breeding a dog could result in something other than a dog. However not only is that not currently testable, it's also brining in intelligent influence into the scenario, and in a way would only support Creationism (intelligent design).
How does that bring intelligent influence into the scenario?

How did the water cut through a mile-deep hole of sheer rock in such a short amount of time? Glaciers form U-shaped valleys, not steep cliffs.

Quote
I understand what you're saying in this analogy, but I'm unsure of how new pieces of paper are added?
Random chance.

Quote
In my original analogy only energy was added to the system, which is like the Earth here. Except my analogy demonstrated that if everything is left to it's natural abilities the energy added to the system would result in chaos, and entropic actions would occur to the paper resembling information loss (populations dieing, mutations, etc.).
Energy added to the system will not necessarily result in chaos. Energy is naturally trying to move away from the Earth into space. This is why the temperature is not continually increasing every second (e.g. temperature goes down at night).

Quote
Also, the canines are still both types of dogs and the analogy doesn't demonstrate that they can become anything but dogs.
I'm saying that C. lephoagus can slowly evolve into other canines, such as Canus lupus and Canis aureus. Canus lupus and Canis aureus are different species of canines that cannot interbreed to form fertile offspring.

Quote
The pieces of paper represented the current state of the sum of organisms in a population. As energy is added to the system (weather elements representing the sun) chaos ensues, and over time entropy occurs to the pieces of paper, and when they fall off of the table they become unusable (this would exemplify traits dieing off within a species). So then the analogy shows that over time chances of any new information forming (as in a functional shape) are infinitesimally small, and the chances of the shape deteriorating into chaos over time is inescapable. That is what I was getting out.
So how, in your analogy, does the population take the place of the swept-off shreds of paper? And who's to say there's only one functional shape? A triangle can have different side lengths and angles, but a three-sided, closed figure is still a triangle.

Quote
The only plausible way for the shape to maintain its state is for some form of intelligent intervention to constantly correct the alignment of the pieces.
Debatable. It's possible that a higher being has shaped life as it is and has been. However, if the designer is omniscient, why are there extinct species? Furthermore, I believe you are underestimating the power of brute force applied to randomness. In no other environment except Earth have humans detected life. On just one planet out of the near-infinite number of worlds do we know for sure that life exists. 1 out of infinity, however improbable, is still possible.

Quote
Not only is there no way for you to know that new genetic information is formed and successfully passed on into the gene pool,
We can observe DNA. We have observed different combinations of DNA molecules. We have seen viruses inject their own genes into a host cell's DNA. We have spliced genes and restructured the DNA of bacteria. We have seen organisms mutate and rearrange their DNA on their own, asexually and sexually. Do you need more examples?

Quote
but to say it's [the creation of new genetic information] more likely to happen than with harmful mutations is absurd. Here's a list of some common genetic mutations currently being passed around: X
You have a finite list of genetic disorders. There is an infinite list of mutations that may help an organism. Things like a straight nose or red hair could be considered a mutation. If anything, a mutation has just as much chance to be harmful rather than beneficial. And as said before, the vast majority of mutations have no effect on an organism's chance of survival.

[quote]
I wasn't saying Earth is a closed system. I was saying that all closed systems deteriorate into the path of least resistance. Similarly, all systems decay towards a state of equilibrium. The Earth is no exception. However the Sun provides energy to the Earth constantly, so the state that Earth is in stays in a nice balance above the state of equilibrium. This is only possible due to chlorophyll harnessing the sun's energy, as energy applied to a system without intelligent intervention results in chaos.
:facepalm: Energy will naturally dissipate back into space without chlorophyll. Neptune has no chlorophyll, and doesn't seem to be evaporating any time soon.

Also, energy applied to a system without intelligent intervention does not necessarily result in chaos. As you said, the Earth is not a closed system (the only real closed system is the universe), so energy naturally moves towards equilibrium (a.k.a. floats back into space).

Pearl Harbor Analogy
I'm confused. Please explain?

Quote
I went ahead and placed a fan blowing wind in a spiral, and put some dust in there (X). You can see a cup also, which represent the earth, while the wind represents the sun. How long will it take before the dust within Earth in the physics simulation to form a recognizable shape? Perhaps a square? If you have an infinite amount of time, it will eventually happen. If you don't, the chances are so small they practically equal 0.
A square is not the only shape that has a possible chance at surviving. A rectangle, or a circle, or a blob 3 inches wide and two inches tall with rounded corners and a half-inch spike coming out the left side could survive in the proper environments. You're saying that 1 out of a large number (infinity, perhaps) is impossible. Once again, it is improbable, but still possible. Thus we have detected life on Earth and no life anywhere else.

@Ezday

May 27 2011, 10:34 pm ubermctastic Post #280



I understand natural selection, but here is the problem.

1 Successful genes get passed on to future generations.

2 The problem was, those genes would have to come from somewhere or we'd eventually end up looking the same.
For this reason, mutations must occur. If they did not, there would be no new genes to be passed on.

3 The problem with mutation is, If an animal mutated, even if it was successful, it would not be able to breed because it is not like the other animals.
People have 23 pairs of chromosomes from the parents while Horses have 32 pairs of chromosomes. If we are supposed to have come from the same ancestors, if a horse mutated to have more chromosomes than it's brothers and sisters, how would it reproduce? If a human ancestor mutated to have more chromosomes than it's relatives, how would it reproduce?
