Red Supremacy

The greatest strength of any species is its capability of adaptation, the faster it can adapt to a change, the more likely it is to survive. Therefore given that every species co-evolves in a biological arms race with one another, this indicates that evolution occurs on an incremental scale, rather than millions of years as Darwin has laid out. Likewise Red supremacy explains the existence of heterosexuality, which both enforces the survival of the fittest and in turn increases the variety within a species gene pool. Additionally both male and female are in competition with their respective sex, rather than just the male as is the common misconception.

One point is that 'fittest' is a metaphor, it doesn't mean Arnie will inherit the earth.
