Rabbits are r-strategists, designed to exploit free resources, like fields of grass. The five psychological traits inherent to the r-strategy are docility/conflict-avoidance, promiscuity/non-monogamy, single-mom'ing, early sexualization of young, and no loyalty to a competitive in-group. Wolves are K-strategists, designed for when resources are too limited for everyone to survive. The five traits of a K-strategist are competitiveness/ aggressiveness/protectiveness, competitive mate monopolization/ monogamy, high-investment two-parent rearing, only mating when mature, and high loyalty to one's competitive in-group. All these traits either help you win, or produce fitter offspring, so they will win.
