Jojo, how does the theory that you believe in result in the different races of peoples? It seems likely that the darker complexion of those that typically live in areas of ample sunlight would give them an advantage due to protection from ultraviolet sunlight. I have also noticed that the inhabitants of the more northern regions tend to have lighter skin.
The people of isolated regions develop characteristics that are different from the nominal such as the red haired Irish or the peoples of Iceland. Is it you belief that the various genes were already present within these groups but for some reason did not become widespread within the overall human population? I guess that this idea would be somewhat like the fact that dogs come in many breeds but most came from one stock which is the wolf. Is this the way you understand the situation? If you carry this to the extreme, a separate group of people that do not come into contact with the population at large might well become very different over eons. I can imagine that as time passes they would be subject to genetic mutations due to radiation, etc. that is not fatal but perhaps others in the group find attractive. Maybe the selection of future mates becomes influenced by this new mutation and they generate more children as a result to pass the trait along. Another possibility is that this new accidental change allows women to survive child birth better such as enlargement of the region where babies pass to be born. Immunity to certain diseases would be a real life saver to anyone that inherits that trait. The relatively recent introduction of the mutation that results in hemophilia was a reverse example of this process at work. The genetic mutation that causes that unfortunate disease is identified and I assume random. It seems that much depends upon the magnitude of the effect that the mutation causes to determine how successful it becomes within people at large. I would find it very difficult to believe that an entirely new animal would arise instantaneously in isolation since it would most likely take at least two of these new critters to continue with the species. This makes it unlikely for a quick change of great genetic variation to become successful. Slow incremental changes that occur randomly in isolated groups might be the trick if allowed to operate over millions of years. I believe that the fossil record tends to support this. There are many species of birds instead of one. That same is true for most animals it seems as I am often amazed at the number of kinds of snakes, lizards, cats, and etc. that inhabit the earth. How does you understanding apply to the many species of birds for instance? Some are remarkably similar but can not interbreed. Just by appearance alone it seems likely that each of these bird species are related in the distant past. Plants offer an enormous example of genetic variation and people have domesticated a large number of them. Take one look at the varieties of maple trees for example. I have a good friend that cultivates dozens of different types for sale. Currently all his maples can be fertilized by any maple, but if they were isolated for a few million years this might not be possible. Oak tree species exhibit a similar variation but can not cross pollinate. Back to the basic topic concept. Data encoded within DNA sounds like a great starting point for long term storage technology. We need to unravel the mechanisms that allow it to be accurately read and I suspect repaired when damaged. I assume it will be possible to use different materials for a similar structure which could allow the new engineered system to withstand high temperature for instance. I suspect that the rate of data storage must be improved by orders of magnitude before a practical solution is generated. My gut feeling is that there will be better methods developed involving optics. I have always felt that a technique such as perhaps 3 dimensional holograms will be capable of immense long term storage capability.

Natural Selection is not the process of DNA building, it is the macro result of mutations. Mutations are the mechanism Darwin claims to be behind changes. The changes result in a survival advantage, hence Natural Selection occurs. Hence the process is in fact a random process. It is important for us to understand that Natural Selection does not occur at the cellular or DNA level. In other words, there is no Natural Selection mechanism to determine at the cellular/DNA level what random mutation is to be retained. That mutation has to cause a change in the macro organism that would confer a survival advantage before Natural Selection can be invoked. You can have many many many mutations or changes at the cellular level but only when changes confer a survival advantage does that mutation get retained. Retention of changes occur at the individual to offspring level - a macro level, not at the cellular/DNA level. If there is no reproduction, there is no Natural Selection. If there is no "survival advantage", there is no Natural Selection. If you understand this, you will understand how utterly impropable Darwinian Evolution is. If we have had infinite time, then yes Darwinian Evolution is possible, but we only have had 4 billion years since the creation of the Earth and 15 billion years since the creation of the Universe. Not enough time. (Note, that I do not personally subscribe the the 4 billion Earth age nor to the 15 billion age of the Universe. I just mention it to highlight the utter fallacy of Darwinian Evolution.) Jojo PS. BTW, I did not start this thread lest Lomax and Jouni will claim that I am starting a trolling thread again. ----- Original Message ----- From: "Abd ul-Rahman Lomax" <a...@lomaxdesign.com> To: <vortex-l@eskimo.com>; <vortex-l@eskimo.com> Sent: Thursday, December 27, 2012 1:20 PM Subject: Re: [Vo]:Digital information storage in DNA >>Natural Selection can not explain how random process can originate >>information; let alone exabytes of information present in DNA in its >>natural state. > > Natural Selection is not Random Process.
