I wouldn't think Adam would have had aforementioned redundant genes, they would have somehow became that way from an ideal state(as I already said)
I don't follow the logic here, are you asserting that these genes would be detrimental? helpful or nuetral, or excess baggage? Please break down you point into some type of digestible package for the common man. I'm really not impressed with big words, my only wish here is that you make some sense.
Also, what possible way can you say that the genes "must have" been in Adam's genome based on the fact that they are found presently?
Most of the time redundant genes are neutral; as they are no longer transcribed into a functional protein they have no effect other than to just sit in the genome.
The assertion is this: if we and chimpanzees have the same redunant genes at the same points in our genome, it is conclusive evidence of a common ancestor.
And so if all humans have them, we must have inherited it from a common ancestor within the last 6-10 million years (this figure comes from analysis of the small differences in the redundant genes due to average mutation rate, and is verified by other genetic evidence and the fossil record) - if adam was the first human 6-10,000 years ago it must have been from him.
So the chimps have the same patterns, all by chance?
I think that you are trying to use similarities of defect as an argument which might provide evidence of a common ancestor. And indeed it certainly does provide such evidence. However, the evidence is certainly not conclusive, it would be better IMO to first make the observation(which you have done) and find more direct causes of the redundant gene rather than saying that a common ancestor passed it down. The question I would pose to you is: 1)What ancestor passed it down first?
A common ancestor of humans and chimps, possibly
Sahelanthropus tchadensis (76 mya) and
Orrorin tugenensis (6 mya), but the evidence is scarse and so inconclusive.
You mentioned that it appeared in other mammals; 2)what other mammals? and what connection do they have with us (what alleged connection is what Im asking)
Alleged? Chimpanzees and bonobos, for certain. They share approximately 98% of our genome, including the imperfections.
and 3) probably the most pervasive question I might have is what, specifically caused the gene redundancy? mutations obviously, but under what condition? in what time period?
No, redundant genes are rarely caused by mutation.
This pathway would require the operon (an on/off switch for the gene) to be mutated, which would render the lot unusable.
Haemoglobin genes (Hb) are multiple-redundant - we have 6 non-functional copies, these can originate as an error in DNA copying. Without the correct operon, the gene would never be used and would just sit there, useless and mutate at an average rate.
If the gene is copied with an operon, it can be used and still allows mutaions that would not produce a toxic product, as we still have the original.
What is striking about Hb is that the copies are found in different locations, different chromosomes in fact.
Out of interest, Myoglobin (the molecule which allows our muscles to handle oxygen transfer so efficiently) is a direct relative of Hb, and we have more than one active functional Hb gene, stanard haemoglobin is made from two alpha and two beta chains. There is also zeta, which is found in embryos.
But it is evidence for us to look at and track down our origins.
I am just more or less helping you present a more understandable argument. I feel that I already answered the question yesterday. Why do redundant genes exist? mutations. What more can I tell you here? As it is I think the scenario your outlining is pretty vague and general to warrant any type of direct answer.
Thanks for your help, but i can't give you a comclusive argument without big words or links to evidence - and you made it clear that you want opinions in laymenss terms, not hard science. So I am stucjkbetween a rock and a hard place here really.
Why do redundant genes exist? Good question, special creation certainly has no answer.
They are purely errors by an imperfect system, yet they can provide the raw material for new genes by mutation.
After all, alpha Hb is only 4 (I think - must check) amino acids different from beta Hb - easily explainable in terms of one copying error creating two genes and one has been modified.
One more change causes sickle cell anemia, good for resisting malaria, not good for normal modern life.
Well, I would simply say that similar processes caused similar genetic changes... I mean basically I can only give a general answer to a general question. I, like anybody else, need specifics. Therefore it is somewhat asinine to think that because someone hasn't answered your questions that no answers exist.
There is no known mechanism that would account for the similarity in human and chimp DNA and special creation. It ties in very nicely with evolution by natural selection, however.
This is definitely evidence of a common ancestor but once again, is it conclusive? Your going to see similar designs across the board and your going to see similar defects, that would certainly be within the realm of a created biosphere.
Similar designs, yes. But not similar imperfections, because humans were genetically perfect only 6,000 years ago, right?
There has not been enough time to accumilate such genetic imperfections, and the odds on it happening twice by chance in different species? not worth calculating. Infinately small, but not impossible.
i would say the odds on producing a working 747 by a tornado randomly blowing around parts of a junk yard is more probable.
Right, but Im not talking about mutagens, though mutagens cause mutations, they dont always cause mutations. Therefore your incorrect if you are assuming that human dna mutates 1000 times per 24 hours. So yes I suggest you produce a link for further discussion please.
You have avoided the point. We have evolved a system to correct and protect against such problems, they arise because the original blueprint for cellular life is frought with problems - badly designed, if you like.
But it works long enough for us to reproduce and raise our offspring, and that's all it takes.
And again, i could have terminal cancer but i can still produce sperm which will not cause that cancer in my offspring, so the mutation per person analogy is misleading - they won't all be passed on!!!
Well correct, your cells will rot in the ground, but if you have children your dna will be passed on, and since I am talking about mutations in dna, then it is very relevant to the population as a whole. All those little sperm cells we were talking about yesterday carry a full copy of your dna to the target.
But it is not identical to the DNA in my body cells as mutation will cause minor differences - the way the sperm cells are created also causes recombination of genes.
How long do you thing the population can sustain the mutational burden?
our population? indefinately. The energy requirements are minimal and we have the technology to deal with it.
The degeneration of the genome is not only evidence against evolution, but it is conclusive evidence. Evolution cannot explain it.
Evolution predicts the random changes in a populations DNA - it is this difference that gives selection the raw materials.
As for the degeneration of the genome, that requires the prior supposition that we were originally perfect and are getting less perfect all the time = bad science.
So there is again no conclusive evidence to refute evolution by natural selection which not only explains genetic difference, it predicted it 100 years before genetic testing.
If you remove your prior assumptions your arguments are not conclusive or supported by any known facts.
I'm sorry, but whoever put these ideas into your head was deliberately trying to mislead you.
