Evolutionary biologist Jonathan Calede may have discovered the oldest amphibious beaver species in the world. Calede first compared measurements of the beaver’s ankle to those of almost 350 other rodent species to learn more about how it moved. __________ Calede dated the species to approximately 30 million years ago based on its location between rock and ash layers.Which choice completes the text with the most logical transition?*A. For example,B. In conclusion,C. Next,D. In fact,
