Due to gross similarities in size, food preference, and appearance, it is often asserted that bison and domestic cattle are ecological analogs. However, a review of their evolutionary history demonstrates that they have significant differences in evolutionary pressures that manifest themselves in strikingly different modes of resource exploitation. Compared to domestic cattle, bison wander…
