What is the relationship between homologous structure and analogous structure?
Wiki User
∙ 12y ago
Homologous structures refer to structures on different species that are similar in function and their evolutionary origin.
Analogous structures are similar in function but do not share a similarity in evolutionary origin.

Homologous structures mean it has the same structure or the same parts ie. a persons skeletal arm compared to one of a cat or a whale. Most of the time the homologous structures have different functions causing for differences in the bone sizes over time. Analogous structures have similar functions ie. a birds wing compared to a butterfly wing but does not have related structures. Therefore organisms with analogous structures

Are similarities between sharks and dolphins homologous or analogous?
analogous
Distinguish between homologous structures and analogous structures?
Homologous structures have the internal structure, but different functions. For example the human arm, horse foreleg, bird wing, and whale flipper have similar internal skeletal structure, but different external structure because of their different functions. Analogous structures have similar external structure because of similar functions, but dissimilar internal structure. An example of analogous structures would be the wings of an insect and a bird.
What are the difference between homologous organ and analogous organ?
Homologous organs have similar embryonic origin and basic structure whereas Analogous organs have different embryonic origin and basic structure. Homologous organs may look different and may perform different function; e.g., forelimb of a man and flipper of a whale. Whereas Analogous organs look alike and perform same functions; e.g., Wings of birds and insects.

How do analogous structures and homologous structures differ?
Homologous features of animals are a lot more recent in contrast to evolution, where as analogous dates far back. Homologous features are similar in structure, but perform different functions, such as the human hands and dolphin flippers, which makes room to allow recent evolution comparisons while analogous consists of wings of a bee and a bird, which are completely different. When trying to determine evolutionary relationship between two species, biologists concentrate on homologous features, as analogous features would be considered useless in this case.
What is the difference between homologous structures and analogous structures?
Homologous = same origin, different function (arms vs. wings) Analogous = same function, different origin (panda thumb)
Two species have homologous structures what do these homologous strcutures show about the evolutionary relationship between the two species?
The presence of homologous structures (for example, the bone structure in chimpanzee arms, human arms, and whale flippers) indicates that the species sharing that homologous structure share a common ancestor.
What is the difference between morphological divergence and homologous structure?
Morphological divergence refers to how different species evolve distinct physical characteristics over time. Homologous structures are similar traits found in different species due to a common ancestor. In essence, morphological divergence can lead to differences in body structures, while homologous structures show similarities in body parts across species.
Homologous structure between birds and dolphin?
they live for a while
Why the homologous structures are evidence of evolutionary relationship?
They show similarities between organisms structure. if the similarities are large then it shows that those organisms share a common ancestor.
