- The pangolin or scaly anteater’s body is covered with scales. How come it is classified as a mammal? Explain. Cite at least three (3) references.Cite at least three (3) scientific reasons why pangolin or scaly anteater is a mammal despite its body covered with scales.Find a representative fish from types A-C. Give the species name of the fish, its family, and what kind of tail it has. Please answer all parts to this question
- To what order does this animal belong (both animals belong to the same order)? This animal DOES NOT possess scales.Why are higher forms of animals bilaterally symmetrical?Explain. Cite at least 3 references.How would the evolution of teeth and bones composed of calcite or aragonite, instead of dahllite, have changed the lifestyles of some vertebrates? Give some specific examples using both fossil and present-day animals. typed answer only
- a- 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). Indicate where the observations and…What do fossils suggest about Australopithecine diet and how it may have varied between the two groups? Explain your answer and be explicit as to what traits support your answer.The tree shows one lineage of ornithischian dinosaurs and many lineages of theropoddinosaurs. Some important traits are mapped on the tree including the aspects of feathers, digits of thehands and a few behaviors. a. What phylogenetic function do the Ornithischian dinosaurs play in this tree?b. What trait is shared by all theropod dinosaurs?c. Only two lineages are thought to be capable of flight. What trait may have helped their wings to bestrong enough?d. What seems to happen to the bones of the hand across this tree of dinosaurs?e. What other bone characteristics might be important to ultimately enabling flight?
