Chapter 30, Problem 14TYU
Summary Introduction
To determine: The place of the newly discovered animal in the cladogram is given in “Fig. 30-6a: Some key characters are indicated on the branches” in the textbook.
Introduction: Animal phylogeny is the rapidly changing field for the biologists. Even if the members of the animal kingdom are incredibly diverse, there are various animals sharing certain features that differentiate them from other organisms of the kingdom.

- Along comes Dr Phil Bell and deep in the mines of Lightning Ridge, finds an amazingly preserved pterosaur that preserves feathers. He hypothesises that this means that feathers must have evolved before the origin of dinosaurs and therefore must have been primitive. Test this hypothesis using phylogenetic framework and provide a brief explanation of your process and whether or not you support Dr Bell's hypothesis.arrow_forwardUse the image to answer the question.

Because of this, you suspect that the vertebrate remains you found might belong to some of the earliest tetrapods (four-legged animals including land vertebrates) to walk the Earth. Examine the cladogram below. What is the sister group to the land vertebrates? Lampreys Sharks Lungfish Land vertebrates Tetrapoda Choanata Fingers and toes Osteichthyes Choanae Gnathostomata Bony ribs and shoulder girdie Vertobrata Jaws O Lampreys Vertebrae O Tetrapoda O Amphibians Lungfish Ray-finned fish Amphibiansarrow_forwardYou are a scientist trying to determine the relationship between the organisms below. 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.

- On a deep sea expedition, you capture a previously undiscovered sea creature that appears to represent a new phyla. It happens to have fertilized eggs that you get to spawn. You watch its development to determine which group of animals it might belong to. You see that the mouth develops first, and it goes through several larval stages in which it molts and regrows its skeleton. Which big phylogenetic group of animals does this animal likely belong to? A. Ecdysozoa B. Lophotrochozoa C. Diploblasts D. Deuterostomesarrow_forwardcreate a cladogram summarizing the phylogenetic relationships among the different Phyla. Take note that some characters may be secondarily lost during the evolution of these different. there is a photo of example of cladogram belowarrow_forwarddraw an evolutionarily accurate phylogenetic tree with the 5 lineages of Amniotes shown in the bottom figure, but with a different arrangement. You can exclude lungfishes and amphibians but include all other lineages. You can do this by swiveling the branches.arrow_forward
