- Which of the following is the correct classification for this chordate animal: This vertebrate possesses hair and mammary glands. They are endothermic. This group gives birth to live young at a fetal stage. Most then nurture their young in a pouch. Question 31 options: a) Class Chondrichthyes b) Eutharia c) Cephalochordata d) Birds e) Urodela / Salamanders f) Class Osteichthyes g) Monotreme h) Reptiles (non avian) i) Anura / Frogs j) Superclass Agnatha k) Marsupialarrow_forwardAccording to a cladistically-based classification system, tarsiers are: A. Prosimians, partly because of their nocturnal habits and small body size B. Prosimians, partly because of the presence of a tapetum lucidum and a rhinarium C. Strepsirrhines, partly because of the presence of rhinarium and vomeronasal organ D.

- Discuss the idea that every evolutionary adaptation has both advantages and disadvantages, using each of the following as an example: (a) cephalization,(b) the arthropod exoskeleton, and (c) segmentation with specialization.arrow_forwardMammals belong to a group of amniotes known as synapsids. Three major lineages of mammals had emerged by the early Cretaceous period. In a tabulated form, compare these three lineages to illustrate their diversity in terms of: a. Embryonic developmen, b. How the young are fed and c. Period of gestationarrow_forwarda- Tiktaalik is a fish that lived 375 million years ago that grew to three metres long and had aquatic features mixed with others more suited to life on land. The fossils of five Tiktaalik specimens reveal that the animals had a large, robust pelvic girdle, a prominent hip joint, and long hind fins. The powerful fins could have propelled the beast in the water, but also helped it walk on riverbeds, or scramble around on mudflats. It is believed that Tiktaalik evolved into four-legged land animals. The scientists have yet to find a Tiktaalik hind fin bone, or any remains that might shed light on the origins of toes. A picture of Tiktaalik is available at https://www.npr.org/2010/07/05/127937070/the-human-edge-finding-our-inner-fish Describe how Darwin would explain that evolution of hind legs (of land animals) actually began as enhanced hind fins (of Tiktaalik), referring to his relevant observations and inferences (History of Evolutionary Thought).
