Are the fins of fish and flippers of whale ,homologous or analogous? Fins of fish and flippers of whales are analogous organs. They perform the same function but they have different basic structure.An example of homologous structures are the limbs of humans, cats, whales, and bats. Regardless of whether it is an arm, leg, flipper or wing, these structures are built upon the same bone structure. Homologies are the result of divergent evolution.The fin of a fish and the filpper of a whale are analogous structures. They have the same job ( function) but different internal structures. This suggests that the DO NOT share a recent common ancestor.
Is a whale homologous or analogous?
An example of homologous structures are the limbs of humans, cats, whales, and bats. Regardless of whether it is an arm, leg, flipper or wing, these structures are built upon the same bone structure. Homologies are the result of divergent evolution.
Are the fins of fish and whales homologous structures?
The fin of a fish and the filpper of a whale are analogous structures. They have the same job ( function) but different internal structures. This suggests that the DO NOT share a recent common ancestor.

Is fish homologous or analogous?
Homologous-Dolphins and fish are both vertebrates, thus they have a similar recent evolutionary history, causing them to have similar body shapes.
Is a fish homologous?
Fish and tetrapods have many homologous organs, which are sometimes altered for the organism’s adaptation to a specific environment. The paired fins in fish and limbs in tetrapods are a good example of homologous organs.
Why are whales homologous?
If you look at the skeleton of a whale’s fin, notice that all of the bones match up to comparative bones in other mammals. This is evidence that whales, as mammals, share a common ancestor with other mammals. Another example of a homologous structure in whales is their inner ear bones.
Are sharks and dolphins homologous or analogous?
Another example of analogous structures are dolphins and sharks as whole species. Although we might think of dolphins and sharks as being relatively similar, their morphology says otherwise. Dolphins are mammals that have live births and have fins with a homologous structure to human arms.
Which pairs of animals shows a correct example of homologous structures?
A common example of homologous structures is the forelimbs of vertebrates, where the wings of bats and birds, the arms of primates, the front flippers of whales and the forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod structure.

Is a whale’s tail analogous?
The whale’s flipper, tail flukes and fish fins are analogous structure because have different structural formation but they perform the same function. Flipper and tails are used in locomotion in the whale and helps the whale in propelling while fins in fish assist the fish in swimming.
What Four animals are listed as examples of homologous structures?
The common structures are the body parts but the difference is the structure. What four animals are listed as examples of homologous structures? Humans, dogs, birds, and whales.
Do fish and whales have a common ancestor?
Cetaceans are the group of aquatic mammals we know more commonly as whales. Cetaceans are readily identified by their smooth streamline shape and lack of hind limbs. They remotely resemble large fish, although whales and fish are not closely related.
Why dolphins and fish are analogous?
Analogous-Dolphins are mammals and fish are not, thus their evolutionary paths are quite separate. They have similar body shapes because of their similar environment. b. Analogous-Dolphins and fish are both vertebrates, thus they share an evolutionary history, causing them to have similar body shapes.
Which of the two animal parts are homologous?
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. They are different and have a different purpose, but they are similar and share common traits. They are considered homologous structures because they have a similar underlying anatomy.

Why is the whale not a fish?
Fish have scales. Whales even give birth to live baby whales that will get milk from their mom for food. Fish lay eggs, which must still grow into a baby fish. So whales are indeed mammals and not fish!
Which pair of structure is not homology between humans and whales?
So, the correct option is ‘Pore arm of humans and fins of fishes‘. Was this answer helpful?
What’s an example of homologous structures?
A common example of homologous structures in evolutionary biology are the wings of bats and the arms of primates. Although these two structures do not look similar or have the same function, genetically, they come from the same structure of the last common ancestor.
Are whales monophyletic?
Abstract. Morphological data have indicated that toothed whales form a monophyletic group. However, research published in the last several years has made the issue of the monophyly or paraphyly of toothed whales a subject of debate.
Is human arm and whale flipper analogous or homologous?
Homologous structures share a similar embryonic origin; analogous organs have a similar function. For example, the bones in the front flipper of a whale are homologous to the bones in the human arm. These structures are not analogous.
Do whales and sharks have a common ancestor?
Similarities between whales and sharks are largely superficial and result from their common aquatic habitat, not from their descent from a common ancestor. Phylogenetic systematics is the name of the field of study in which genealogical relationships among species and clades are discovered.
Are fish fins and whale flippers homologous?
Fins of fish and flippers of whales are analogous organs. They perform the same function but they have different basic structure.
Are dolphins and sharks homologous structures?
…

Is a shark fin homologous?
Analogous structures are similar structures in unrelated organisms. These structures are similar because they do the same job, not because they share common ancestry. For example, dolphins and sharks both have fins, even though they aren’t related. Both species developed fins because of how (and where) they live.
What are some homologous structures shared by all mammals?
All mammals, for example, have fur and mammary glands, among other traits. These shared traits may be similar among related organisms, like the tails of cats, dogs and monkeys. Or they may be modified, like the wrist bones of whales and humans. These shared structures are called homologous traits.
