Choose the true statement(s) about the evolutionary divergence of horses in North America. Check all that apply. 

_____ Most changes are seen as adaptations for life in grassland habitats.
_____ The general trends during horse evolution are increase in body size, lengthening of limbs, reduction of digits on both sets of limbs, and tooth development for a grazing life style.
_____ Horse evolution is unusual in that rates of change were uniform and constant throughout most lineages.
_____ Living lineages of horses show much less diversity than existed in the past.
