Taxonomy STAAR Review

Bactrian camels, dromedaries, llamas, and alpacas are all members of the same taxonomic family, Camelidae. Members of this family all have two toes, no hooves, true canine teeth, and a split upper lip. The family Camelidae originated in North America. The physical features of animals in this family and the family’s geographical origin provide evidence that all these animals —

• live in the same type of ecosystem

• have slowly evolved to become herbivores

• have a common ancestor

• exchanged DNA at some point in the past
