That's not really how it works though. Natural selection necessarily occurs whenever reproduction happens, it's just the evolutionary pressures and the traits that we end up selecting for that change.

Nature 'selects' via scarcity of resources. The 'fittest' survives due its comparative competitive advantage over its peers for a specific set of resources. It necessarily entails that said set of resources isn't enough to satisfy everyone.

Take away scarcity, nature selects everyone.

Resource scarcity is just one evolutionary pressure that can direct natural selection.

Consider bacteria, for example. Even if you place them in an environment with an inexhaustible supply of nutrients, if you add small amounts of antibacterial chemicals, you will end up breeding bacteria that are resistant to those antibacterials.

That's.. survival of the fittest ain't it? Here, scarcity lies not with their nutrient supply, but ways to deter their chemical killers?

Edit: I guess I am taking on a broader look at the term 'resource'.
