"But kidney disease, Parkinson's, Alzheimer's and vulnerability to malaria and the human immunodeficiency virus (HIV), which recent research has blamed on single-letter variations in the gene code, are also suspected for CNVs."

ok... so out of 3,200,000,000 letters in the DNA code you just misplace/mutate ONE SINGLE-LETTER out of its right place and you get something as bad as HIV&all the other serious diseases???
seems that 99.(9)% of the mutations damages°enerates the DNA code, they're decreasing the amount of useful/correct genetic information throughout the process of natural selection/adaptation... so the facts are that all the living things are INVOLVING and NOT evolving...
a specie highly adapted to a specific enviroment has lost genetic information and can't go back to it's original vast genetic state, because of that genetic information lost during selection.
so natural selection just SELECTS from the existing gene pool, it doesn't CREATE any new useful genetic information as evolution would require in order to be true

This person has no idea how molecular biology functions. A single nucleotide can copy incorrectly and cause a certain condition, such as in sickle cell anemia, however, it could also potentially mutate another nucleotide that would have some unknown, perhaps beneficial mutation. In addition, just because a gene MAY copy incorrectly during DNA replication, does not mean that it will. It does not always produce negative effects. Although sickle cell anemia may seem bad, in the context of evolution it makes sense. The populations most afflicted by sickle cell anemia have their genetic roots in areas where malaria is endemic. The misplaced nucleotide in this case, effects the hemoglobin gene. This mutation causes hemoglobin to be produced that misshapes the red blood cells in those afflicted into a sickle shape. This causes them to potentially form blocks and clots in the body. However, it also prevents the malaria parasite from living a part of its life cycle, which normally takes place on normal red blood cells in humans. Although the condition causes pain and sometimes death, it is not as bad as having malaria, hence those who possessed the mutant gene were more likely to pass it on, as those without it were more likely to die of malaria sooner and more frequently than those who had sickle cell anemia. Hence its presence today in those populations.So to summarize my example there, sickle cell might be seen to be a "bad" thing, but it simply was a random mutation that provided a benefit to the population that carried it. Genetics and molecular biology as we understand it today would not be possible without evolution. If you take insulin for diabetes, or any of the new slew of cancer drugs, you have scientists and their great understanding of biology, biochemistry, and especially evolution to thank for that.

What if the human race is actually multiple races seeded here on planet earth; a product of DNA experiments preformed by extratrestrial beings? Could that explain some the the variances in DNA that we see between the different races and possibly lead to the question: where are the missing strands of DNA?
