Homologous = same origin, different function (arms vs. wings) Analogous = same function, different origin (panda thumb)
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.
analogous
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 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.
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.
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.
describe a chemical test you would use to show the difference between an isomer and a homologous series
they live for a while
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
