They are considered homologous structures because they have a similar underlying anatomy. What are similarities between sharks and dolphins? Although their differences are certainly substantial (e.g., sharks are cold-blooded and dolphins are warm-blooded), sharks and dolphins have some undeniable similarities: side fins, a dorsal fin, and a torpedo-shaped body. Streamlined bodies and fins provide a big advantage for them, allowing them to swim faster. Analogous Evolution If two species face a similar problem, challenge or opportunity, evolution may end up shaping them both in similar ways. 11. The 2 flowers .

Homologous structures share a similar embryonic origin; analogous organs have a similar function. Consider similar traits in both sharks and dolphins. There are many similarities and differences between a shark and a whale. Describe how two unrelated flowers could evolve to have a similar appearance? These structures are similar because they do the same job, not because they share common ancestry. What is morphology? Dolphins, which evolved long after sharks from land mammals, adapted to the water with similar physical characteristics. Their streamlined bodies, dorsal fins and flippers are the result of convergent evolution. c) What is Thylacosmilus?

The fins of sharks are very rigid and sturdy because they are supported by cartilage. Similarities Between Homologous and Analogous Structures. Answer: Dorsal fins of dolphins & sharks = analogous but NOT homologous (serve same purpose but evolved completely independently) pectoral fin of dolphin & bird wing = homologous but NOT analogous (structures perform totally different functions but derived from same origin in common stem ancesto. 10. c) What is Thylacosmilus? Do you think that sharks' and dolphins' similarities (body shape, fin, and flippers) are homologies or analogies?_____ Bottom of Form. Sharks and dolphins are made up of eukaryotic cells; their common ancestor remains a mystery, and most of their similarities are analogous structures. 13. Their skeletal structure is homologous due to common descent from a reptilian ancestor's forelimb; however, the modifications for flying are distinct and independently evolved, and they are analogous in this regard. (hint: click the highlighted . When taking a look at felines and humans one may notice the similarities between the limbs and feet. The matching limbs in the game have bones, and you eliminated the limbs that don't have bones. Describe how two unrelated flowers could evolve to have a similar appearance? Homologous Trait Between Humans and Felines. Their backs are a dark gray or blue, and their bellies are a light gray or white. Similarities between these two species are analogues with the only thing they have in common are that they both have characteristics that allow them to efficiently swim. Both humans and felines are mammals, which means both have a skeleton made from bone, are warm blooded, have a presence of hair/ fur and glands specialized to produce . They are different and have a different purpose, but they are similar and share common traits. Although we might think of dolphins and sharks as being relatively similar, their morphology says otherwise. Homologous and analogous structures are developed by evolution. What is morphology? 12.

Homologous structures share a similar embryonic origin; analogous organs have a similar function. Both dolphins and sharks swim after prey in the ocean. What three criteria are used to determine whether something is a homology or analogy? Fill in the blanks of the primate tree. What's the Difference Between Homologous and Analogous Structures? 12. Even though sharks and dolphins share many characteristics, that doesn't mean they are related. 3 13. species' shapes and colors may evolve in ways that make them more attractive to the bird. Also, the shark has evolved from fish, making these two species Analogous. They are considered homologous structures because they have a similar underlying anatomy. For example, dolphins and sharks both have fins, even though they aren't related. 1. Sharks, on the other hand, are cartilaginous fish and, despite the superficial similarity between their fins and the fins of a dolphin, which serve similar purposes, these organs in this animal are analogous to those of the dolphin, since they arose from structures Different embryonic plants are anatomically different, but they exert the same . 13.

A B D C . … We know that dolphins and sharks are not closely related, and they didn't inherit their similar body shapes from a common ancestor. Both species developed fins because of how (and where) they live. Describe how two unrelated flowers could evolve to have a similar appearance? Homologous and Analogous Traits. Analogous, they evolved for the same purpose (swimming) . For example, the bones in the front flipper of a whale are homologous to the bones in the human arm. Streamlined bodies and fins provide a big advantage for them, allowing them to swim faster. Slide 10: Studying homologies and analogies 1.
