Are we undermining our own evolution?
conanite: Evolution often occurs when due to changes in the environment (climate change, new diseases, new predators) vast numbers of the species die off. The marvels of modern medicine are a less traumatic alternative.For example, if evolution were to have its way, HIV should kill off those humans who lack the CCR5 gene. This would be bad news for most Africans and Asians, as well as up to 95% of people of European descent.The deletion mutation of CCR5 in Europeans is possibly an evolutionary adaptation to mediaeval European plagues - the Black Death and smallpox. (see http://en.wikipedia.org/wiki/CCR5 )We don't have a moral obligation to evolve. I'll stick with medicine, personally. As well as clothes, houses, electricity, supermarkets, central heating and air conditioning.
