Analogous Structures Example
A great example of analogous structures are a bat’s wing and a bee’s wing. Bats and bees do not share common ancestry, so the structures cannot be homologous. Both bat wings and bee wings serve a common purpose – helping bats and bees fly! The structures look similar on the outside, too.
analogy, in biology, similarity of function and superficial resemblance of structures that have different origins. For example, the wings of a fly, a moth, and a bird are analogous because they developed independently as adaptations to a common function—flying.
Analogous Structures Examples Within Nature
Bird, Insect and Bat Wings. Fish and Penguin Fins/Flippers. Duck and Platypus Bills. Cacti and Poinsettia Plant Structures. Crab and Turtle Shells. Turtle and Bird Beaks. Octopus and Human Eyes. Shark and Dolphin Coloring.
Organisms that have evolved along different paths may have analogous structures—that is, anatomical features that are superficially similar to one another (e.g., the wings of birds and insects). Although such structures serve similar functions, they have quite different evolutionary origins and developmental patterns.
Homologous structures share a similar embryonic origin; analogous organs have a similar function. For example, the bones in the front flipper of a whale are homologous to the bones in the human arm. These structures are not analogous. The wings of a butterfly and the wings of a bird are analogous but not homologous.
Though there is no limit to the possibilities when it comes to word analogies, here are some examples to familiarize yourself with the concept:
hammer : nail :: comb : hair.white : black :: up : down.mansion : shack :: yacht : dinghy.short : light :: long : heavy.bees : hive :: bears : den.speak : sing :: walk : dance.
So, the correct answer is ‘Lungs of Man and Gills of Prawn’.
Examples of Analogous Structures. The wings of a bird and of an insect are analogous organs. Both of these species have wings that they use for flight and yet their wings came from dissimilar ancestral origins.
For example, the bones that make up human fingers were inherited from an ancestor that’s shared by all mammals. Bats, dogs, and whales also have these bones, but bats use them to spread their wings, dogs walk on them, and whales do not use them for anything since they are encased inside their fins.
Following are some examples of homology: The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar and share common traits.
Homologous structures are similar physical features in organisms that share a common ancestor, but the features serve completely different functions. An example of homologous structures are the limbs of humans, cats, whales, and bats.
Historically, anatomical and developmental differences among eyes of different species favored homoplasy; however, recent molecular data indicating that all eyes employ a similar cascade of transcription factors (proteins regulating gene expression) for development have suggested homology.
The Eyes of octopus and human are examples of analogy or convergent evolution. Brains of vertebrates are an example of homology or divergent evolution. Similar structures (brain) evolve in different species due to similar evolutionary origins.
