Re: The Evolution Thread
I do not believe that any kind of human evolution is going to occur in a dozen generations. The larger the human population, the larger the gene pool, and when you combine this with greater globalization, changes in the gene pool will slow to a crawl. Evolution occurs more rapidly in small isolated populations. You may see outward changes, most likely an increase in racially complex people. But this is only outward appearance in phenotype. The underlying variation in the gene pool will not change. For instance, over time we may see a lower propotion of people exhibiting the recessive blue-eye trait, but the proportion of blue-eye alleles to brown-eye alleles in the gene-pool will remain the same.
