Homologous structures are structures that indicate a related evolutionary ancestry, not just similarity. For example, the flipper of a whale, the wing of a bird, and the arm of a a human are similar in their bone structure.
Analogous structures are structures that are similar in appearance and function but are not the result of shared ancestry. For example, the wings of a birds and insects have the same function, but they do not reflect a shared ancestry.

What homologous structures in different species evidence of?
Homologous structures in different species are evidence of a common evolutionary ancestry. These structures have a similar origin, but may have different functions in different species. Studying homologous structures helps researchers understand how species have diverged and evolved over time.
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.
What are homologous structures between birds and bats?
Birds and bats are homoplasious because they are similar, but not derived from a common ancestor. An example of homologous structures is a man's arm and a cow's foreleg. They are anatomically similar but have different functions.
When classifying organisms in a cladistic diagram identify three pitfalls scientists might encounter classifying creatures?
Animals may have similarities that developed separately and should not define them as closely related, there may be periods of time when they evolved quickly that are not known about, and it can be based a lot on assumption
Besides comparing the structures of an organisum taxonomists also compare the organisums geographic distrobution and what?
Besides comparing the structures of organisms, taxonomists also compare the organisms' geographic distribution and their reproductive strategies. These additional factors help provide a more comprehensive understanding of the relationships among different species and their evolutionary history.
Are rock wallabies homologous or analogous structures?
Entire organisms are rarely referred to as structures. When you ask if they are analogous or homologous, that requires something to compare the structure to. Is the toenail of a rock wallaby homologous to a hoof? That would be a question that could reasonably be answered. What you have asked does not have enough information to be answered and should probably be trashed.
Both homologous and analogous forms of these result from evolution?
Structures
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)
How are analogous and homologous structures different?
They are different because homologous structures have the same structure, but serve a different function. Like mammal arms(human, bat and whales). Analogous structues are different structures, but serve the same function. For example, bat wings and butterfly wings.
Is a wing of a bird homologous to the wing of a cat?
In biology, homologous structures are defined as structures which serve the same purposes because they evolved from the same source (divergent evolution), the opposite of analogous structures, which serve the same purpose but evolved through convergent evolution. Birds' wings and bats' wings are both homologous and analogous. As wings, the two are analogous, but as forelimbs, the two are homologous.
What is the difference between homologous analogous and vestigial structures?

Are the wings of birds and the wings of bats homologous or analogous structures?
They are both. They are homologous because they are both examples of a vertebrate forelimb. They are analogous because they were adapted for flight independently of one another.
How are homologous structures different from analogous structures?
Homologous structures are similar in structure but can serve different functions in different species due to evolution from a common ancestor. Analogous structures, on the other hand, have a similar function but arise independently in different species due to convergent evolution.
What do homologous structures and analogous structures have in common?
Homologous structures and analogous structures both relate to the study of comparative anatomy and evolution. They demonstrate how different species can develop similar features in response to environmental pressures or evolutionary paths. While homologous structures arise from a common ancestor and share a similar developmental origin, analogous structures serve similar functions but do not share a common evolutionary origin. Both types of structures provide insight into evolutionary relationships and adaptations among species.
What is the relationship between homologous structure and analogous structure?
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.
The wing of a bat and the foreleg of an alligator are?
Homologous structures are those that have similar looks based upon a common ancestry. THE ANSWER IS HOMOLOGOUS STRUCTURES!!! On the other hand, analogous structures are structures that have the same function. Bats fly, but alligators walk.
Structures that have similar structure and function but different evolutionary origins are called?
It is either homologous structures or homozygous structures. Embryological structures are when different species of animals look similar in the earliest stage of development and Analogous structures are when animals look different but their function is basically the same. So just look up homologous structures and homozygous structures in your Bio book!!
