homologous structures- same structure/different functions in common ancestors
analogous structures-same functions/differnt structures not in common ancestors
vestigial-show evolutionary history/structures that arent used anymore (i.e. human appendix/human tailbone)
Homologous structures are body parts of different organisms that have a similar form, suggesting a common evolutionary origin. These structures may serve different functions in each organism but share a common ancestry.
Structures that are similar due to common ancestry are called homologous structures. These structures may have different functions but share a similar underlying anatomy, indicating a shared evolutionary history. Examples include the bones in the limbs of vertebrates, which have a common origin despite being adapted for different purposes in different species.
Homologous structures are anatomical similarities in different species that suggest a common evolutionary ancestry. Similar structures in organisms that share a common ancestor are expected to be derived from that common ancestor. By studying these homologous structures, scientists can infer evolutionary relatedness and reconstruct the evolutionary history of species.
If two different animals possess homologous structures, it means they share a common evolutionary ancestor. These structures may serve different functions in each species, but they have a similar underlying structure due to their shared ancestry.
A hand and a paw are homologous because they share a common evolutionary origin. Both structures have similar underlying skeletal elements, such as bones and joints, which suggests they have descended from a common ancestor. Despite differences in function and appearance, the shared ancestry points to their homology.

A structure with similar shape but a different use
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.
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.
Scientists refer to similar structures as homologous structures. These are traits that are shared between different species due to common ancestry, even if their functions may have evolved differently over time.
Homologous structures.
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.
Homologous structures among animals are similar body parts that suggest a common ancestry. These structures provide evidence for evolution because they indicate that different species share a common evolutionary history and have evolved from a common ancestor.
