Subspeciation in the Kangaroo Rat, Dipodomys ordii KU. Vol 1 No 23

"Subspeciation in the Kangaroo Rat, Dipodomys ordii" by Henry W. Setzer is a scientific study concentrating on different types of kangaroo rats; the text explores where they live, what they look like, and how they changed over time presenting ways to sort them into specific groups. It begins by explaining where these creatures are typically found, noting the difficulties in telling the subspecies to each other. The publication refers to previous efforts to classify these animals, explaining the key characteristics that permit these kangaroo rats to live in dry, sandy areas, and lays out what the study will explore by examining how they look on the outside and inside, where they live, and how they evolved into different forms.
