This chapter describes the simpler, more durable, but equally important relationships cows develop with one another. The forebears of bison cows must have experienced both plenty and scarcity in their evolutionary history — times when dominance was worth fighting for and times when it wasn't. Changing circumstances select for changeable behavior, with different strategies for different times and places. The bison pay the costs of striving for dominance when the benefits are high, and don't when the benefits are low. Being a dominant member of a group has high potential payoff. In Yellowstone Park, subordinates searched more and harvested less than dominants. A dominant will eat everything it clears and some that it doesn't clear. A subordinate will eat only part of what it clears.
