Question 35 options: a) Birds are more closely related to amphibians then they are to reptiles. b) Birds are a type of reptile, but are not related to dinosaurs. c) Birds and reptiles are the least related vertebrates. d) Birds are a type of reptile and are descended from a group of dinosaurs.What are the two ways of finding the age of a fossil? Describe how relative dating works. What does absolute dating do? Why is the element carbon-14 important for paleontologists? . Developmental Biology - Embryology Many scientists use what an organism looks like as an embryo, or embryology, as evidence for evolution. The embryos of most vertebrates look very similar and have similar structures. For example, fish, bird, rabbit, and human embryos are similar in appearance in early stages. They all have gill slits and a tail with muscles to move it. Later as the embryos develop, they become less and less similar. What does the study of embryology show when comparing most vertebrates?

- Which is the only wrong statement? Group of answer choices small mammals and non-avian dinosaurs co-existed some non-avian dinosaurs invented flight non-avian dinosaurs were a very short-lived group birds and large, slow-moving dinosaurs co-existed birds are currently living avian dinosaursSelect all the possible evidence that can be use to support the Theory of evolution 1. Fossil records from the Jurassic 2. Hind leg bones in whales 3. Finger prints from humans 4. Homoplasies 5. Comparison of the femur of humans, birds, dogs and whalesMammals have a particularly good sense of earing thanks to their inner ear which includes three tiny bones. Reptiles, in contrast, have a single inner ear bone. The lower jaw of reptiles is composed of multiple bones while the lower jaw of mammals is a single bone. Fossil and developmental evidence indicate that the inner ear bones of mammals evolved from lower jawbones. This suggests that the inner ear bones of mammals are 1. an analogy 2. an exaptation 3. a living fossil 4. a transitional trait 5. a vestigial structure
