Species Embryo (A-F) Describe the Anatomical Changes from Early to Late Stages Human Chicken Rabbit Tortoise Salamander В Fish A Guide Questions: 1. Look again at the six embryos in their earliest stages. Describe the patterns you see. What physical similarities exist between each of the embryos? 2. Does this suggest an evolutionary relationship? Explain how these embryos can be used as evidence of a common ancestor between each of these six organisms.
POSSIBLE F Some large snakes, such as pythons, have small internal lég bones. These bones are examples of fossilized organs vestigial structures transitional forms homologous structures 1 3.

Hagfish Salamander Lizard Perch Mouse Chimp Pigeon Feathers Fur; mammary glands Claws or nails ungs Jaws Fig. 1. Cladogram on some vertebrates Related questions: 1. What is the synapomorhpy shared by the mouse and chimpanzee? Answer: 2. Specify the apomorphy of the pigeon. Answer: 3. Jaw is present to what taxa? Answer:
6. Organisms classified as “birds” share a common feature. What shared derived character defined this taxonomic group? 7. What feature is present in all animals but is not present in birds and reptiles? 8. Reptiles, birds, and mammals are amniotes. I’m addition to an amniotic egg, the common ancestor of all reptiles, birds, and mammals had a thick epidermal layer of scales partially composed of a protein called keratin. Keratinized skin helps prevent water loss in terrestrial environment. A. what type (or form) of Keratinized epidermal structure represents the ancestral character state of all reptiles, birds, and mammals?
Figure 12.8 Which animals in this figure belong to a clade that includes animals with hair? Which evolved first: hair or the amniotic egg?

TRUE OR FALSE 1. The fossil record provides a sweeping overview of the history of life over geologic record 2. A change in the regulation of a developmental gene may have fewer harmful side effects than a change to the sequence of the gene. 3. Synapsids possess an opening known as the occipital fenestra behind the eye socket 4. In some very late cynodont the articular and quadrate bones migrated into the ear region, where they functioned in transmitting sound 5. Fossils contain isotopes of molecules that accumulated in the organisms when they were alive.
This organism is an animal. What can you infer about its bodystructure and lifestyle (that might not be obvious from itsappearance)? This animal has a protostome developmentalpattern and a trochophore larva. Identify the major clades thatthis animal belongs to. Explain your selection, and describe whenthese clades originated and how they are related to one another.
