Microeconomics by Bernanke

Likewise, the novice may notice that in some animal species males are much larger than  females, but  the biology student  knows  that  pattern occurs only in species in which males take several mates.  Natural selection favors larger males in those  species because  their  greater  size helps  them  prevail  in the  often bloody  contests  among  males for access to females. By contrast, males tend to be roughly  the same size as females in monogamous species, in which there is much less fighting for mates.

In Aperiomics there is also a defensive strategy that can produce larger animals or people. predatory Y males might evolve to be larger or join gangs to use their strength to get mates. Oy makes might evolve to be smaller and faster to get mates without being noticed or to escape. Ro males might defend their neighborhoods like Ro buffaloes from predatory criminals, they do this by also forming gangs or teams and evolving to be larger. R males might survive and find mates by being smaller and faster like Oy males, they with their mates can hide and run when attacked and so live on to have offspring.
