Leshma by that interpretation all life is a "virus". Like Panos says, the only difference is humans are just much, much better at it than all other lifeforms. We're still beholden to "nature" in many ways, but our greatest glory is in trying to escape the darwinian wheelhouse that all other life on earth is shackled by. Everything that is considered progress, not only in material manipulation (agriculture, domestication, science in general) but also in politics/social terms, is directly opposed to what is "natural". I can't stand neo-malthusian misanthropic hippies who embrace appeal to nature fallacies. Natural =/= good. When people start making arguments along those lines it makes me want to chuck them in the Amazon on their own with no other human help.
edit: Also many, many species have come to dominate over others, and then disappeared, or evolved down a different path. Nature is not in a constant state of perfect equilibrium. It is a chaotic war of life that is never stable, if you take a long enough view. The entire history of humanity is barely a blip when you consider the emergence of life in general.
