Evolution: Changing the nature of life.

What is your evidence for Evolution. Note, this does not mean basic mutation, such as fruit flies with eyes on their legs, or birds whose becks have altered to better accommodate their food. I am refuring to entirely new systems, organs, tissues or cells that drastically alter their creature's nature. If possable, please provide links to references.

How about being able to trace evolution through the fossil record? Don't ask for links, I really don't care to have to prove a scientific fact to anybody.

[GestaltAlteration]

Mutation through reproduction. Duh. Uh, that's your evidence? Looks like a statement.

[Sornaensis]

Yep.

[Keeper]

Define drastic. Well, what would you consider drastic? I'm kind of wishy-washy on this part: I supose anything that seems like it could lead to a new organic system and/or grant the life a new ability that was - on a genetic level - prevoiusly unavalable. That is why leg-eyes and new becks don't count: The genes were already there. How about being able to trace evolution through the fossil record? Don't ask for links, I really don't care to have to prove a scientific fact to anybody. How does that prove Evolution? ... and why post in here unless you where going to back up your assertions? [edit] Mutation through reproduction. Duh. Explain please?

[Jdeadevil]

Was that thing about penguins flying a joke or not? Sorry but I seriously don't know....

[GestaltAlteration]

Yep. That's no better than "evolution because banana".

Don't kill me for being wrong here.. but i don't THINK whole new organ systems suddenly appear, it's more like this: It is important to recognize that mutations are changes to the genome, the set of instructions that dictates how an organism develops. Therefore, every non-silent mutation makes the organism that has it slightly different from every other member of its species. It may be something as simple as a tiny alteration in the shape of a blood protein, or something as complex as a change to the skeletal and muscular structure that determines the body's ultimate shape. The point, however, is that each mutation makes the organism different in some way, and over thousands or millions of years, these differences add up. Eventually, as mutations spread and accumulate, a population of organisms may evolve to a point where it is considered to be a separate species from the population it descended from. This is called speciation or macroevolution so basically every little mutation will add up until you do come out with an entire new working limb or a new organ or something. Though really you;d have to find an article or book on evolution, i'm sure it covers new organ systems and other dramatic changes.

Disabled people? Sorry? [Edit] Cuddly: So it cannot be observed in any real sence?

[Sornaensis]

That's no better than "evolution because banana". ...? It is a fact that changes occur to the DNA of an organism when it reproduces itself. That is the base of evolution and is hardly like "Evo bec. banana". Firstly, it is a fact. Second, I really shouldn't have to explain the base of it, especially a well accepted fact, on a forum for the eleventy bagillionth time. Explain please? When an animal reproduces, mutations and general changes to the DNA are the root of evolution. Asking for a new animal is asinine as humans have only been actively and globally studying animals for a few thousand years, and evolution has only been a concern the past few hundred. However simply looking at how animals variegate is another explanation. Without evolution breeds of dogs or horses, etc. would not exist. Viruses could not adapt. Humans would not be of different sub-races.

[Serkat]

Sorry? A mutated human. And yes, it can be observed. It takes quite a while. You should get a cup of coffee or two if you plan on observing evolution as it happens.

[GestaltAlteration]

You come here, to a thread with the purpose of asking for the evidence of evolution. If you're too lazy to provide evidence, than you shouldn't admonish me for raising an eyebrow at your one-line post. Yes, It's a fact that micro evolution occurs, but what of macro? If you're tired of explaining it than don't post in a thread asking for it. Is that really so hard?

[Sornaensis]

Micro evolution... Is the root of macro... Those terms are just categories of the same event and you people just don't seem to get that.

[GestaltAlteration]

Because your posts aren't convincing or informative in the least, they're just you talking. Can't say I've ever learned anything from you.

...? It is a fact that changes occur to the DNA of an organism when it reproduces itself. That is the base of evolution and is hardly like "Evo bec. banana". Firstly, it is a fact. Debatable, but that is the purpose of this thread. Second, I really shouldn't have to explain the base of it, especially a well accepted fact, on a forum for the eleventy bagillionth time. Your repeating yourself. When an animal reproduces, mutations and general changes to the DNA are the root of evolution. Asking for a new animal is asinine as humans have only been actively and globally studying animals for a few thousand years, and evolution has only been a concern the past few hundred. I'm asking for a new type of cell at the least. Surly a new type has been observed? How else could Evolution be a fact? A single, never before seen cell that performs a unique action in a creature. However simply looking at how animals variegate is another explanation. Without evolution breeds of dogs or horses, etc. would not exist. Viruses could not adapt. Is that simply not the change of preexisting genetic traits? Humans would not be of different sub-races. A mutated human. Not all. I can't say I have ever heard of someone born paralyzed, though I'm probably wrong on that score ... And yes, it can be observed. It takes quite a while. You should get a cup of coffee or two if you plan on observing evolution as it happens. could you give me a timetable ... oh, and I detest coffee with every fiber of my being

There is tons of evidence of common descent among animals from homologous structures to similar biochemical organization. You can observe this in living animals, and in the fossil record. Common descent proves evolution, if you really need this illustrated further, take an introductory level biology class. And of course we can observe all the different mechanisms that evolution works through. We can observe the shift in allele frequencies in populations using models like Drosophila. Variation has primacy in reproduction. Gene linkage, mutation, recombination, these are things that are built into meiotic division. /edit wait, how does this have anything to do with religion and spirituality right now?

[Sornaensis]

Yea, you don't get it. Evolution does not create a "new type" of anything. Subtle changes over time. Why do you think many animals on earth share common features? Eyes, nose, four limbs, enclosed brain, same general flow of the skeleton, etc? Humans are so infantesimally small and we can only observe such a tiny portion of life that observing anything "new" is inheretly impossible. See "Niche".

[Serkat]

Is that simply not the change of preexisting genetic traits? Yes. And you don't see the difference between a Chiwhuawha (however the fuck to spell them) and a bulldog? Fish, Apes and Human all have a common ancestor and developed into what they are today through "change of preexisting genetic traits", as you said. Note how they all have bones? Not all. I can't say I have ever heard of someone born paralyzed, though I'm probably wrong on that score ... Anything counts. I think you heard of savant idiots. That's a less subtle way to spot how evolution can work.

[Keeper]

Yea, you don't get it. Evolution does not create a "new type" of anything. Let me say nothing. Subtle changes over time. Why do you think many animals on earth share common features? Eyes, nose, four limbs, enclosed brain, same general flow of the skeleton, etc? Please don't tell me that this is your proof: that they look and function alike. This argument works for both sides: if it works, use it. Humans are so infantesimally small and we can only observe such a tiny portion of life that observing anything "new" is inheretly impossible. See "Niche". So are you saying it cannot be proved? [Edit] Yes. And you don't see the difference between a Chiwhuawha (however the fuck to spell them) and a bulldog? They are still dogs, not cats. Fish, Apes and Human all have a common ancestor and developed into what they are today through "change of preexisting genetic traits", as you said. Note how they all have bones? Let me put it to you this way: How did the bones form? What gradual mutations caused that? Anything counts. I think you heard of savant idiots. That's a less subtle way to spot how evolution can work. But do they have new systems?
