You are given the task of finding all the information that you can about a newly discovered species. Unfortunately the only material you have to study is a small tissue sample. You are able to sequence the DNA of this animal from the sample, and in doing so you find that the animal has multiple clusters of Hox genes. Without looking further, what can you conclude about this species? Check all that apply.
_____ It is a vertebrate. _____ It has the potential for tremendous structural complexity. _____ It is a chordate. _____ It is endothermic. _____ It is a primate.
