Question

3.03 points Imagine a scenario in which you, as a recently graduated zoology major, are accompanying an older high school teacher on a field trip. Students are trying to identify as many different classes of vertebrates as they can observe. At the end of the field trip, their list includes all of the traditional vertebrate classes. In addition to other vertebrates, the students observed snakes, lizards, and numerous bird species. Their list of classes included the classes Reptilia (for the snakes and lizards) and Aves (for the birds). To the surprise of the teacher, you tell the students that modern zoologists would suggest that their division of birds and reptiles into separate classes is probably groupings for these animals. Knowing that you have been recently trained in zoology and that his understanding of vertebrate classification is probably out dated, the instructor is somewhat embarrassed. Which of the embarrassment? Select all that apply. not the best following responses would be appropriate and help alleviate the teacher's older classification systems are still used because many older zoologists just don't like the newer cladistic approaches. Traditional classification systems are firmly embedded in zoological literature and subfields of zoology are organized to reflect this classification system. Drastic changes in vertebrate taxonomy would be quite chaotic Our knowledge in science often advances faster than the terminology we use to describe what we know. Sometimes we must use traditional taxonomic labels knowing that we must qualify their use by describing how they do not accurately reflect evolutionary relationships.

Explanation / Answer

Option 3 is more appropriate.

Vertebrate classification based on their skin covering, how they reproduce, how they maintain body temperature, and characteristics of their limbs (arms and legs, or their equivalent such as wings or fins).
