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.
analogous
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.

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.
Homologous = same origin, different function (arms vs. wings) Analogous = same function, different origin (panda thumb)
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.
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.
they live for a while
They show similarities between organisms structure. if the similarities are large then it shows that those organisms share a common ancestor.
Analogous means that the structures have different origins, but they do the same things. Homologous means the opposite: that they have the same origins but are adapted to do different functions.
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.
