On a separate sheet of paper create a cladogram that represents how these animals are related. the words below in bold, must be used on your cladogram 1. Divide the animals into two groups depending on if they possess vertebrae. 2. Divide the vertebrates into groups according whether they have an amniotic egg or not. (Hint: keep the animals who give live birth with the amniotic egg animals.) 3. Divide those who have amniotic eggs according to the presence of an exoskeleton. 4. Divide those with endoskeleton according to whether or not they give live birth. 5. Divide those with live birth depending on if they possess opposable thumbs. 6. Return to your invertebrates. Divide them according to the presence of an exoskeleton. 7. Divide those with exoskeletons according to whether they possess wings.

- Which of the following is not a known bias in the fossil record? Fossils from well-studied areas are more likely to appear in the fossil record More abundant species are more likely to be found and in the fossil record Mammals preserve better than birds. Shells and skeletons preserve better than soft-bodied animals.arrow_forwardTransitional species are species important in helping scientists determine the evolutionary path that species have taken over long periods of time. Lobe-finned fishes are the ancestors of amphibians and have fossils that are found in rocks that are at least 380 million years old. Fossils of the oldest amphibian-like vertebrate animals with true legs and lungs are found in rocks that are approximately 363 million years old. Paleontologists have found a sample of rock that is approximately 370 million years old which contains what seems to be a link between lobe-finned fishes and amphibians. Which of the following is a characteristic that you would not expect to see in this transitional fossil? Question options: Skeletal structures that indicate the development of legs. An intermediate structure between lungs and gills. Teeth that are intermediate to the lobe-finned fishes and amphibians. A neck that is more flexible than lobe-finned fishes.arrow_forwardCreate a cladogram based on the morphological and molecular evidence. Comparative Morphology Data.
