Homologous structures are any structures that have similarity and come from the same lineage. This can be seen in the forelimbs of mammals.
Analogous structures are very similar but come from different ancestors. This can be seen in the North American flying squirrel vs the Australian sugar glider. They both have similar features but come from 2 different locations. In fact, the Australian sugar glider is more related to the kangaroo than the flying squirrel

What is the difference between homologous analogous and vestigial 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)

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.
Are similarities between sharks and dolphins homologous or analogous?
analogous
What is the difference between analogous and homologous?
Analogous structures are similar in function but not in evolutionary origin, while homologous structures are similar in structure and evolutionary origin but may perform different functions. Analogous structures result from convergent evolution, where organisms adapt to similar environmental pressures. Homologous structures indicate common ancestry and evolutionary relationships between species.
What are the difference between homologous organ and analogous organ?
Homologous organs are similar in structure and origin but may differ in function, whereas analogous organs have similar functions but different origins and structures. Homologous organs suggest a common evolutionary ancestry, while analogous organs are a result of convergent evolution.
Distinguish between homologous structures and analogous structures?
Homologous structures are features with a similar anatomical origin but have different functions, indicating common ancestry, such as the limbs of vertebrates. Analogous structures have similar functions but different anatomical origins, suggesting they evolved independently due to similar environmental pressures, like the wings of birds and insects.
If Whales and cats are both mammals Are the whale's front flipper and the cat's front leg homologous or analogous and why?
Neither one. Both homologous and analogous structures refer to similar structures. But a cat's front leg and a whale's front flipper have little in common. Homologous structures come from little evolutionary separation, and analogous structures come from convergent evolution. But the differences between a cat's front legs and a whale's front flipper result from divergent evolution. The common ancestor of mammals (cynodonts) has split into various groups with widely differing characteristics. One such group includes cats, and another includes whales. These two groups are not very related to each other, thus having no homologous structures, and have been put in very different environments, thus having no analogous structures.
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.
Are bird wings and butterfly wings homologous structures?
There are a few different similarities between the wing of a butterfly and the wing of a bat. Both are used to fly for example.
What causes the difference between the ancestor and modern koalas?
a. the presence of homologous structures b. the presence of vestigial organs
