(SuperGuz believes living organisms can consciously control their genetics, or in some form of Lamarckianism, submitter can't quite tell which)

[If your "theory" were correct, there shouldn't be any. Why are the Australians of European descent incapable of manipulating their own phenotypes so their skins are appropriately dark [enough to prevent skin cancer]? You yourself claim that "the course of a few generations" should be enough to do it. Why isn't it happening?]

you must first show me that this isn't true. Got any studies on families that show scientifically that even though they are exposed to pounding effects of the sun that they have not increased their pigmentation over multiple generations? Your baseless assertion doesn't cut it. What city in australia are you referring to? There are different environments in Australia. Sydney, for example rarely gets above the 80s and often has cloud-cover.
