They are the same thing.

They are the same thing.
Natural selection and evolution by natural selection are the same thing. Migration, mutation, natural selection, and gene drift are mechanisms of the evolutionary process. Natural selection plays a huge role in the evolutionary process and denying natural selection is denying evolution. Evolution cannot work without natural selection because taking natural selection out of evolution leaves you with a huge missing piece of the puzzle on why specific organisms survived and why specific organism did not.No there not.
Evolution means all living things are descendants with modifications.
Natural Selection, is a way of explaining how it works.
The forces of natural selection act on phenotypes, but only if there is a change in the genotypes of a population has evolution occured.

I think you might want to read up on natural selection again. Evolution by natural selection is not a seperate theory on evolution, it is rather an integral part of it.
No where did I state that evolution and natural selection were the same. I only challenged your notion that natural selection and evolution by natural selection were different. I said natural selection is an integral part of the evolutionary process, meaning it's a mechanism that explains evolutionary theory.Yes I agree, but they are NOT the same thing. You corrected me on the Evolution by natural selection being the same as natural selection. But Evolution, by definition is not the same as Natural selection. And you can have one without the other. It is possible because Evolution takes billions of years, meaning right now......you can have natural selection in the wild, with no evolutionary mutations. So yes, you can seperate them.

If you couldnt then every single generation of children would show visible signs of mutation or evolutionary type advances....And if that were true there would be no home run record, no fastest mile record, no nba single game scoring record, because all of these records would have been broken with the coming of each new generation. Therefore, evolution is not visibly taking place every generation. And if it is, Its more like De-evolution....because kids are not getting any smarter with the coming of brainless television and poor education systems.
During the recent Republican Presidential Debate the question was asked, Who doesnt believe in Evolution? Three of the candidates actually raised their hands: Brownback, Huckabee, and Tancredo. The capacity to deny the overwhelming evidence that supports bio-chemical evolution spotlights their capacity for self-delusion. Moreover, it shows their ability to disregard a preponderance evidence in favor of a religious belief. In my opinion, no one with those characteristics should be President.
As for evidence.... There IS overwhelming evidence that within a species evolution occurs and works as advertised. I would say that that small piece is all but proven. The problem is there is absolutely no evidence to support the theory on the emergence of totally different species from an original species. That part is all assumptions.
Until the science can provide hard evidence that such occurs that part is simply wishful thinking.
You seem to be confusing natural selection with success. Also, you seem to be equating athletic records to some sort of phenotype, which they definitely are not. For example, the best athletes could be made through hard work and mental toughness, which come from nurture, not nature. Just because you hit a lot of home runs, that doesn't increase the number of children you produce. I don't see how these athletic records are applying a selective pressure on the number of offspring produced anyway.
I think that evolution is slowing down in humans anyway, since we have been removing these selective pressures in developed parts of the world. For example, we now have modern medicine to help treat disease, removing some of the pressure on the body to fight the disease. This is not to say that our immune systems will get much worse, but that in modernized parts of the world, disease does not apply a significant pressure to select for favorable mutations in the immune system.
Evolution and natural selection are somewhat connected. If you believe in natural selection, you must believe in evolution and vis-versa. Natural selection is broader though, and evolution is essentially a subset of natural selection referring to specific circumstances. Evolution is essentially natural selection under the conditions that the selected phenotype has an associated genotype.
Well, as I said before, Natural selection Is not Evolution. Dont you people read? Natural Selection is the Mechanism of Evolution. It is a theory, not a fact. Evolution is a fact. There is evidence that supports this fact, but new scientific discoverys have produced different theorys of The mechanism of Evolution. If you dont know what im talking about then you are not up to date on science, you are looking back not foward. Natural Selection IS a theory and It is NOT evolution, It is the theory of the Mechanism of Evolution, or the process in which evolution could take place.
If someone can show me identical definitions of the two, I will throw away my books and believe you.
They are not the same thing, but they are necessarily connected. You can't have evolution without natural selection, and vis-versa. Natural selection is equivalent to a car, and evolution is a specific type of car, say a new Toyota Camry. You are correct in saying that the definition of a natural selection and evolution are not identical, and analogously a new Toyota Corolla is not identical to the definition of a car. However, you are wrong in saying that you can have Evolution without natural selection. That is like saying you can have a new Toyota Corolla without having a car. See, it is possible for two things with different definitions to be necessarily connected.
Did you not read my entire post? Natural Selection is not even widely accepted as the best theory of the mechanism of evolution? Yes natural selection does exist as a fact and plays a role in evolution, but it is only speculated that natural selection is the MAIN cause (Mechanism) of evolution.
Do you know what Modern Synthesis is?
Darwin was unaware of genes and genetic drift. The modern theory of the mechanism of evolution differs from Darwinism in three important respects
1. It recognizes several mechanisms of evolution in addition to natural selection. One of these, random genetic drift, may be as important as natural selection.
2.It recognizes that characteristics are inherited as discrete entities called genes. Variation within a population is due to the presence of multiple alleles of a gene.
3.It postulates that speciation is (usually) due to the gradual accumulation of small genetic changes. This is equivalent to saying that macroevolution is simply a lot of microevolution.
In other words, Modern Synthesis is a theory about how evolution works at the level of genes, phenotypes, and populations whereas Darwinism was concerned mainly with organisms, speciation and individuals.
Yes Darwin did discover natural selection and it is proven. But he believes that natural selection was the cause of evolution which is simply not proven. It may play a role, but it is not the mechanism of evolution, at least not without hard evidence. And with modern synthesis, we have genes and genetic drift as hard evidence.
Don't take this personally Vintij but it's my opinion that you've really misunderstood the concepts of evolution theory. I'm under the impression that you just wiki'd natural selection and evolution in the last couple of days. I didn't want to call you out on it earlier but it's pretty clear you bungled very specific terms like mutation, adaptation, and natural selection while wrongly using evolution as a blanket definition. Darwin's theories on natural selection are sound and you've clearly misunderstood them. I think you're talking over your head.
Huh??????? You're grasping now.Ofcourse darwins theorys are sound. Who said otherwise? He is a pioneer. It is your theory that natural selection is the only mechanism of evolution, that is unsound. Science is always changing with technology and infact, the theory of evolution existed long before darwins time. He is the one who put research in, and gave it a real explanation. See I will admit that I know nothing about psychology, or neuroscience. I wont go into those subjects pretending otherwise.
I never said that natural selection is the only mechanism of evolution, what I said was that you can't challenge natural selection but still believe in evolution. Someone who leans towards "Modern Synthesis" should know that evolution is co-dependent upon natural selection and genetics.Me said:Natural selection and evolution by natural selection are the same thing. Migration, mutation, natural selection, and gene drift are mechanisms of the evolutionary process. Natural selection plays a huge role in the evolutionary process and denying natural selection is denying evolution.

How much do you know? You talking high school classes here? You just previously argued that evolution by natural selection was different from natural selection. You also wrongly referred to mutation as evolution; adaptation as evolution; you wrongly referred to a decrease in human performance to de-evolution; and you also said that evolution was dependent upon the theory of common descent, which it does not.What I do know, is Biology and Astrophysics. Therefore I am inclined to speak my mind on the subject from what I have learned so far.
Huh??????? You're grasping now.

Ok, now your are twisting my words. I said that Evolution by natural selection is different from natural selection itself. Meaning it is possible to study natural selection based on different organisms, without forcing the evolutionary theory that permanent change is needed to create natural selection. (which I have shown you that permanent change and mutation are not proven through natural selection)
I never said mutation or adaptation is evolution, it is a sub-topic of evolution that natural selection can not explain on a major population type level, and on a permanent level without going back to its original nature.
Please show me where I said, literally mutation is equal to evolution, in that case, people with physical disorders have evoloved? No I never said that.
What I meant when I said natural selection is different from evolution is not that it has nothing to do with it....no that is not what I meant. What I meant was that natural selection alone, can not prove evolution as it has no explanation for genetic drift. Please show me the link where natural selection proves evolution exists! Please I would love to see it. See I know evolution exists, and maybe im being a jerk by not buying into your general knowledge of neo-darwinism. But......I am not going around spouting that Evolution must exists because natural selection proves it. No I would never say something like that because I know it is simply not true and if it is, it is simply not proven yet. Natural Selection is a big part of evolution, but I do not personally believe it to be the main mechanism of evolution....That is my opinion.
I did not literally state that contemporary human performance is de-evolution, you are all wrong on that part. I was being sarcastic, and even boarder line comical when I said that. How can you take that seriously?
Nor did I say that evolution is dependent on the theory of common decent. Again, If you read clearly....I was being sarcastic when I wrote about baseball players and performance. Please dont confuse that rehtoric with actuall research.
Please stop confusing my argument with anti-darwinism or creationism. I embrace neo-darwinism and there would be no logical evolutionary theory without it. I just have my own opinion on the mechanism of evolution. Surely with your masters degree you would understand that nothing is set in stone when it comes to science, other than scientific laws.
I don't frequent science message boards...threads like "how to construct your own lightsaber" don't hold my interest.I respect you and I have nothing against you at all. Infact I enjoy talking with you, and would love for you to enlighten me on more subjects. Do you have any recomendations for books or websites. I have been looking for a website to discuss science with other people on a message board or chat room.

Hmmmm, I wonder if anyone here has ever started a thread on another message board about building lightsabers?
