Uhhh, wow. That is a question I have never entertainedFor instance, was Adam black, white or asian?

there have been a lot of genetic studies showing that the first modern men were african, and had dark skin. they have certainly been around for at least as long as 'uncolored' people, in fact there is much support saying that blacks were around before any other types of skin color.bizzt wrote:Who said their were even Colours back then?Mastriani wrote:Bgood asked:Uhhh, wow.

Can you point to the exact statement's that you say are incorrect and that this demonstrates the error, because I don't remember anyone claiming that Children are exact copies of their parents.

Asexual reproduction is the simplest form of reproduction, occurring in many simple plants and animals. Binary fission, shown here occurring in an amoeba, is one of a number of asexual reproduction processes.
Examples of asexual reproduction. Asexual reproduction is the simplest form of reproduction, occurring in many plants and simple animals. Strawberry plants can reproduce by sending out runners; onion plants form bulbs; and potato plants form tubers. Amoebas divide into two (binary fission) and hydra form new hydra by budding. The offspring are always genetically identical to the parent.
I never made the claim that sexual reproduction shows more stability than asexual reproduction. Sexual reproduction ensures that the offspring will recombine stable information.
Asexual reproduction ensures exact copies. Which means if there is a gene mutation that causes a member of the species to perish, it will certainly mean that line becomes extinct.
Sexual reproduction does not create exact copies, otherwise, you would not be discernable from your father or brother. It ensures that if a certain genetic mutation occurs to the detriment of the species, by combining with another mate, that mutation can be "weeded" out, thus ensuring the survival of the species.
all the 'information' (the order of pairs--G,C;T,A--that make up a DNA strand) is basically the same from generation to generation. what happens is, through meiosis, genes are recombined and the order gets rearranged. also, mutations occur in the genes which can add, subtract, or change a certain set, or few sets, of bases in DNA. so pieces of DNA are rearranged, and within those pieces, parts are changed. so yes, most of the information is stable, but it is still rearranged.Jbuza wrote:IT is clear from observations that individuals make up gene pools of sexually reproduced organisms. It is clear from the similarities amongst the individuals within a gene pool that some of the information is incredibly stable. And stable across generations.
What is stable is viable life.Jbuza wrote: Can you point to the exact statement's that you say are incorrect and that this demonstrates the error, because I don't remember anyone claiming that Children are exact copies of their parents. IF I did see that I would agree with you completely.

Well all the human's I have ever seen and skeletons of some I heven't have some traits in common. I will not list them they are obvious. These traits are vry stable and appear to be resistant to change.BGoodForGoodSake wrote:Show how a specific trait is stable.

The original point is that traits have changed over time. Since obviously Adam cannot be rainbow colored.bizzt wrote:How can one go about to Prove this. Do we have Skin or some kind of DNA from the Bones we collected? What is this Much Support that you speak of?

Traits in common yes, however there is variability among these traits.Jbuza wrote:Well all the human's I have ever seen and skeletons of some I heven't have some traits in common.

Take the isolated wolf populations from a previous link. This population had congenital spinal chord defects.Jbuza wrote:really care to demonstrate thisBgood wrote: It's not the DNA because isolated populations don't show this stability.

Variability is what evolution is supposed to work on.Mystical wrote:Who brought humans into this discussion? We are irrelevant to it. There are no different species of humans; just on species: humans.
The comparative differences between and family members is less than that of strangers. When looking at overall genome however there is very little differences. As you can see a few small changes leads to all the variety in the human race.Mystical wrote:So, humans in a discussion of evolution is pointless. Two other things: human DNA is incredibly stable. There is virtually no difference between different races in different parts of the world, or family members and strangers.
It may happen on occation, but you make it seem as if it occurs all the time.Mystical wrote:Also, on the skin color issue: traits have not changed over time. Blacks bear white children commonly and whites/hispanics bear black and white and "rainbow" colored children quite commonly. So, I ask again, who brought humans into this discussion?
Anthropomorphizing again? I don't think evolution is working on anything. This thread was criticizing macroevolution. In that case, humans have nothing to do with this discussion.Variability is what evolution is supposed to work on.
Quite strangely, it is the other way around.The differences between family members is less than that of strangers.
As I can see, there is only one human species. Doesn't say much for evolution. Says alot about it...As you can see a few small changes leads to all the variety in the human race.
Happens enough.It may happen on occation...
Umm, no, why would you do that?Because of this we should stop asking questions?
Wow! Good questions! I don't know anyone who's ever asked those? BGood, I sure hope you find the answers 'cause you're really spending alot of time on this.Why...What...Does...And...
humans actually show evidence for evolution. have you ever met two humans that are exactly alike (not even twins are the same)? every human is different because their genes are different. there are more noticable differences in humans who have adapted through isolation in different parts of the world (race). we are similar to our parents because our genes are made of recombinations of their genes (causing a few minor mutations, most likely). so human dna is incredible stable because any tiny change in our dna is likely to cause a major change in our physical structure. and the human body has become very efficient as it is. but changes still occur. recombination causes the differences between father and son, and it allows for some dormant genes to become active in the next generation (as shown by genes for hair loss and some susceptability to certain diseases).Mystical wrote:Who brought humans into this discussion?
