Reason and Revelation

Hi,
This is not evidence for evolution, but just mixing of genetic information ? .
I don't catch your response. I mean, most variation that exists in domesticated animals has not existed in their wild predecessors! Besides, you also ignore the other evidence I put forth like the taxonomic hierarchy and fossils, which are not necessarily related to genetics.
Tha makes me wonder, are you confused about evolution? What is your definition of evolution?

Hi Andya
There is no evolution. There is no evidence for it. How is the genome reprogrammed? This has to achieved if for evolution has to occur. But not just this but even if this occur at level of a particular cell-type, how would this information/change gona be accomodated in a particular species. I am a molecular biologist, and am looking at evolution at molecular level. Hence, I do not see any evidence. To make it simple, just tell me how the genome is reprogrammed if there is evolution?

Your definition of evolution please. You can't just go claiming 'there is no evolution' without even saying what you think as evolution. Some of the evidence I have put forth led Darwin to propose his theories of evolution.
New variations arise all the time within the genome due to mutations and recombination. How is it that you choose to ignore this line of evidence?
-
Hi Andya,
Thanks for your replay.
I agree with you that new variations arise through mutation and genetic recombination. But this is just genetic mutation and recombination. An environmental impact generating a mutation is often not good or fatal, also one should not get confused with adaptation, where nothing is added or taken away from the genome. For argument sake, even if mutations does occur in me through evolution, which by some "luck" give me some advantages, how is this gonna pass on to my next generation? Isn't this needed for evolution to occur? Lets don't go around in a circle. These is no evolution because there is no evidence for it.

That's why I'm baffled with your reply. You do know that you pass your genes to your offspring, right? Suppose a mutation happens in the DNA in your reproductive cells. This mutation might be inherited by your offspring. I thought you should know this?
By the way, what do you consider evolution is? You haven't answered that.
-
Hi,
Obviously there is no evolution, there is adaptation. If there is evolution then just give me one example or a scientific evidence to proof it.
Where is the evidence for evolution? Even if there is a mutation in my re-productive cells, it does not mean its gonna pass on to my next generation, even by chance it pass on, what is the chance its gonna benefit my next generation. Give me an example if such thing has ever occured.
Peace

Obviously there is no evolution, there is adaptation.
If you can say things like this then you at least have an idea of ehat evolution means .
Now, what do you consider to be evolution? As far as I know the study of adaptations is one field of evolutionary biology.
-
No i disagree. Adaptaion is not evolution. The difficulity with evolution is there is no evolution. If there is evolution then show me some scientific facts. Just one will be enough. As a scientist, I do not consider evolution because there is not a single scientific fact about it.

Hi bmbmm,
I have been following this discussion but dont see it going anywhere.
But what I couldnt help noticing was,Dec 8
This is how evolution is defined
It is important to note that biological evolution refers to populations and not to individuals and that the changes must be passed on to the next generation. In practice this means that, Evolution is a process that results in heritable changes in a population spread over many generations. This is a good working scientific definition of evolution; one that can be used to distinguish between evolution and similar changes that are not evolution.
Another common short definition of evolution can be found in many textbooks
"In fact, evolution can be precisely defined as any change in the frequency of alleles within a gene pool from one generation to the next."- Helena Curtis and N. Sue Barnes, Biology, 5th ed. 1989 Worth Publishers, p.974
Is this how you define evolution?
Dec 16
Then what do you consider to be evidence of evolution, then?
Dec 17
What is your definition of evolution?
Dec 18
Your definition of evolution please.
Dec19
By the way, what do you consider evolution is? You haven't answered that.

Now, what do you consider to be evolution?
And ur replies have always been something like ur last one
No i disagree. Adaptaion is not evolution. The difficulity with evolution is there is no evolution. If there is evolution then show me some scientific facts. Just one will be enough. As a scientist, I do not consider evolution because there is not a single scientific fact about it.
No disrespect to u, But looks to me, that ur definition of evolution is highly awaited by the people discussing here and also those following the discussion. So, do us all the favour and define evolution. )
Peace!

Hi Peacefulmuslim.
There is no definition for something which has no scientific evidence. Its not there; how can you define something that does not happen? Where is the evidence for evolution? Its a simple question, no disrespect to anyone out there. I find it interesting to discuss these things but we have to have logic and give evidence first. I got one evidence for evolution "A blind watch maker" lol
-
Hi bmbmm,
This is the real definition of evolution a process in which something passes by degrees to a different stage, especially a more advanced or mature stage.
Now were is the evidence for this?Atlast, ur definition is out.
Thank God.Peace!
-
Okay. You've defined your understanding of evolution, which is roughly correct IMO, except for some parts.
Evolution is change through time, but it doesn't happen to 'something'. Evolution happens to populations/lineages through time. You and I, individuals, don't evolve; what evolved is the lineage we're in, the lineage that led to modern humans.
Also, evolution doesn't necessarily go from 'simple' to 'advanced/mature/perfect/complicated'.
You ask for the evidence of evolution, defined as change through time. The evidence for this is the fossil record. We see that organisms in the past are different from organisms today. Going through fossils from different periods in time, we learn that the forms of organisms are changing. This is one of the evidence that led to the realization that evolution, defined as change through time, happens.
That clear?
-
Most obvious form of evolution.... Domestication of animals. Over time that domestication changes the physical appearance as well as the physiology of a species or breed of animal. Also you can consider cross breeding and a kind of forced evolution. To evolve, to change, to create a new gene pool
-
A particular cellular function goes from DNA>RNA>mRNA>Protein. It does not go from the other way, such as Protein>mRNA>RNA>DNA. If evolution has to occur this has to be achieved, and its not. Why not? Because its not as simple as that; the DNA is translated faithfully by a machinery of proteins to a piece of RNA in the nucleus. It is then transported to the cytoplasm by a machinery of proteins through the pores of the nucleus. This RNA is processed by a machinery of proteins, were the Introns are removed and the Exons are jouined together. After joining it become mRNA (messenger RNA), which is edited further by a machinery of proteins, and a poly A tail is addded to its 3' end and its 5' end is Capped to stabalise it. This mRNA is then translated by a complicated machinery to produce protein, which at the same time pushed in to the ER by a machinery of proteins, where it take its functional shape in a split second! Some of these proteins are then further processed by a machinery of proteins, such as N-terminally blocking it, for stability.
What evolution is saying that all this has evolved, I want to know how? There is not a single scientific fact about it ! .

Sometimes things adapt to the surrounding due to the activation and/or silence of certain genes at the level of transcription or even translation. However the overall genomic DNA is fixed, it doesn't change. It does change sometimes with mutagens and/or radiation which is not good and often desasterous.
-
Peace bmbmm, all
You said that mutations in the DNA do occur due to radiations. Don't you think that the god who created all that exists, can send a meteorite with the specific velocity and composition... so as that the impact with the earth, would produce the very specific amount of radiations that is necessary to provoke mutations in some specific species and exterminate others?
This process could be repeated as much as needed to produce the multitude of species that populate the earth; Just have a look at the surface of our neighbour the moon, you would be amazed of how often this phenomenon occurs.
This is one possible way to provoke 'jumps' in evolution, there are surely other ways.
