(actually flaps of skin stretched between the legs) of sugar gliders and flying squirrels homologous or analogous structures? There are many similarities and differences between a shark and a whale. Describe how two unrelated flowers could evolve to have a similar appearance? They are considered homologous structures because they have a similar underlying anatomy. The body shape and body color of sharks and dolphins are very similar. Streamlined bodies and fins provide a big advantage for them, allowing them to swim faster. The human has skinny phalanges and are shorter in comparison to the phalanges of a dolphin. The answers may surprise you! 11. What three criteria are used to determine whether something is a homology or analogy? 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 . 5. In morphology: Anatomy …environments, a phenomenon known as convergent evolution. The similarities between bat and bird wings are partly homologous and partly analogous. Both sharks and dolphins swim after prey. Homologous and analogous structures are developed by evolution. For example, sharks and dolphins look relatively similar despite being entirely unrelated If the anatomical structures listed are sharks and dolphins homologous or analogous are examples of convergent evolution fish that have fins swimming! homology and analogy( understanding evolution answers Homology and analogy( understanding evolution answers. They are considered homologous structures because they have a similar underlying anatomy. Are similarities between sharks and dolphins homologous or analogous? 9) Are similarities between sharks and dolphins homologous or analogous? Their streamlined bodies, dorsal fins and flippers are the result of convergent evolution. This means that sharks' and dolphins' similarities (body shape, fin, and flippers) are convergent traits that each lineage evolved independently. Sharks are classified within the fish family while dolphins are mammals. Since the octopus, sea star, and grasshopper limbs don't have bones, you concluded that they are . What is morphology?

Homologous and Analogous Traits. 11. What is . Both have streamlined bodies which make them agile swimmers Both are carnivorous Homologous Structures Evolution Some examples of convergent evolution include the relationship between bat and insect wings, shark and dolphin bodies, and vertebrate and cephalopod eyes. Are similarities between sharks and dolphins homologous or analogous? Convergent evolution gives rise to analogous structures but not to homologous structures. Homologous-Dolphins are mammals and fish are not, thus their. Homologous and analogous structures are developed by evolution. The dolphins bone structure appears to be more compact and has a shorter humerus bone, pulling . 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. A B D C . We'll start by playing a game to get you thinking about similarities and differences. Describe how two unrelated flowers could evolve to have a similar appearance? Not all similarity is homology. Hint: Analogous organs are those organs that do not have the same origin but their function is the same . Homologous features are similar in structure, but perform different functions, such as the human hands and dolphin flippers, which makes room to. The dolphins bone structure appears to be more compact and has a shorter humerus bone, pulling . The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. Dolphins, which evolved long after sharks from land mammals, adapted to the water with similar physical characteristics. species' shapes and colors may evolve in ways that make them more attractive to the bird. Dolphins lineage does not have any line of previous mammals who have fins. When taking a look at felines and humans one may notice the similarities between the limbs and feet. What type of evidence is this? They are different and have a different purpose, but they are similar and share common traits.
