Are Shark and dolphin fins analogous or homologous?
Analogous!
How can the ethical debate surrounding the harvesting of shark fins versus dolphin fins be compared in an analogous manner?
The ethical debate surrounding the harvesting of shark fins and dolphin fins can be compared in an analogous manner because both involve the controversial practice of killing marine animals for their fins, which can lead to negative impacts on the populations of these species and their ecosystems.
Is a fish fin an analogous structure to the whale flipper?
Yes, a fish fin and a whale flipper are considered analogous structures because they have similar functions (swimming) but are derived from different evolutionary origins. Fish fins are adaptations for movement in water, while whale flippers are modified limbs evolving from a common ancestor with land-dwelling mammals.
What are analogous characters derived from?
Analogous characters can be traced to a distant common ancestor. Although they may differ in appearance, and somewhat in function, the analogous characters (traits) developed from an earlier functional trait. (Example : fins in fish, hands and feet in humans)
What is squid's fins structure?
don't seeds
Are the legs of a cat and the fins of a whale homologous or analogous?
Neither. Homologous structures are similar because two organisms came from a common ancestor. Analogous structures are similar because two unrelated organisms were subjected to similar environments. But the legs of a cat and the fins of a whale are not similar enough to be characterized as either homologous or analogous. The ancestors of whales were hoofed mammals, and one could argue that a hoofed mammal's leg and a cat's leg are homologous. However, after millions of years of being in the oceans, whales' fins have adapted such that they are now not at all similar to the legs of a cat.
Are the legs of a cat and fins of a whale homologous or anologous?
The legs of a cat and fins of a whale are analogous structures because they have different evolutionary origins but serve a similar function in terms of movement. Homologous structures would be when two species share a common ancestor and have similar structures with different functions.
What is the importance of the fins of a shark for human use?
Humans use the fins of sharks in certain soup dishes
Would whitebait have fur feathers or fins?
Whitebait is a type of fish so it would have fins.
What structure supports fins?
The structure that supports fins in aquatic animals is made up of bony rays or cartilage. Fins are extensions of the body that help animals navigate, stabilize, and move through water efficiently. They vary in size and shape depending on the species and their specific needs for swimming.
Do reptiles have fins on the outside of their body?
Some reptiles possess characteristics which may resemble fins, but no, reptiles do not have fins. Fish have fins. An example of a fin-like structures on a reptile would be a dewlap. This is a flap on skin under some lizard's necks used primarily for territorial and mating displays. Although the fins of fish may be used for these purposes to some extent, the primary purpose of fins is moving through water. Another fin-like structure on a reptile would be a frill around the neck. The purpose of a frill is the same as a dewlap.
Are penguin flippers and bat wings homologous or analogous?
Yes they are. I disagree. Even if they ultimately come from a common ancestor, in order to classify two characteristics as homologous, they have to have some similarities. After millions of years of being in the oceans, the fins of whales have evolved such that they are not at all similar to cats' legs.
