Your argument, Kyle, that sickle cell anemia is a detrimental mutation is a relative question. My point is that the environment in which an organism lives and survives, the myriad obstacles it faces, and the behavior it exhibits will demonstrate whetheror not the genotype of that organism has fitness or adaptability. This is seen through basic observation. I guess you would call this micro-evolution, otherwise known as proximate evolution. However, what processes cause the observations we see. Why would a gene for sickle cell anemia exist, other than (detrimental)mutation? 3/27/2003 4:41:51 PM
