QUOTE (looking_for_truth @ Jun 21 2008, 09:39 PM) I'd like to play devil's advocate here (and put out there some of the issues I've been struggling with). Firstly Antlerman made the point that the impression (great distinction between 'impression' and 'evidence' BTW) of God derived from the perfection/near-perfection of the universe, i.e. the argument from design, is akin to "Bob ...

"Exactly, jiperly. One of the things that has been noted on many threads is that genetic diversity increases our chances of survival. One example is sickle-cell anaemia. The gene occurs in areas where malaria is epidemic, and ensures that carriers don't get malaria. If malaria spreads in an area where the population doesn't have the genes for sickle-cell anaemia and treatment is not provided ...

Actually, I disagree with this interpretation of the buffering effect of modern society. While it has allowed many genetic mutations to survive when they would have been removed from the gene pool if modern medicine didn't exist, at the same time it has increased the general variation in our species. Not all "detrimental" mutations are "bad" in all environments. A perfect example of this is ...

Quote: People from malaria prevalent areas are genetically predisposed to have sickle cell anaemia. But you aren't. You either have the gene or you don't. You're not 'predisposed' to have the gene unless you have it. If you have ancestors from that area, you're more likely to have the gene, but you're not 'predisposed' to have it. Maybe it...

Monty40xi wrote: The majority of mutations are neutral. The majority of NON-neutral mutations are harmful. And that fact in itself is a form of selection, and a useful one. Another good example of mutations and harm are the very small group of semi-harmful mutations, the poster-child of which is Sickle Cell Anaemia: SCA is a harmful, frequently deadly disease that restricts activity and ...

Eaglewise: Explain the different races and distinctive features and genetic variations of man. Racial differences are largely insignificant but, relatively isolated populations within different areas succumbing to natural and sexual selection. Examples would include - increased or lessened melanin in the skin due to cope with solar exposure, or lack thereof, different prevalence of ...

Could be a side affect. A gene that is beneficial in some way also makes somebody more vulnerable to the condition. Sickle cell anaemia is caused by having a pair of genes that in singleton form cause resistance to malaria.

Gursuchi I hope you have done these questions but if you have not, these are definitely most asked questions which i have copied from other thread of this forum. Good luck with final preparations. 1.
