Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. Figure below shows the hands of several different mammals. They all have the same basic pattern of bones.

Homologous and Vestigial Structures
When two different species have anatomically similar structures, we call them homologous structures. These structures look similar but don't necessarily have the same function. These anatomical similarities show how closely related two creatures are.
What is an example of anatomical 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. They are considered homologous structures because they have a similar underlying anatomy.
What is an anatomical homologous structure and what are some examples?
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.
What are the similarities between homologous and analogous structures?
Similar traits can be either homologous or analogous. Homologous structures share a similar embryonic origin. Analogous organs have a similar function. For example, the bones in a whale's front flipper are homologous to the bones in the human arm.
How are homologous and vestigial structures alike?
Homologous structures are the similar anatomical structures of evolutionary-related animals. Most often, these structures perform a similar function. ... In comparison, vestigial structures are the anatomical structures that have reduced their size as they are no longer used by the animal.
What is anatomical homology?
Anatomical homologies are morphological or physiological similarities between different species of plants or animals. Comparative anatomy, which is the study of anatomical homologies, is the source of most traditional evidence for evolution and common descent.
What is an anatomical structure?
An anatomical structure is any biological entity that occupies space and is distinguished from its surroundings. Anatomical structures can be macroscopic such as a carpel, or microscopic such as an acrosome.
What are homologous anatomical structures?
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. ... The forelimbs of all mammals have the same basic bone structure.
Why anatomical and molecular features often fit a similar nested pattern?
Explain why anatomical and molecular features often fit a similar nested pattern. ... Specific anatomical and molecular features are shared by a narrow range of species are not shared by a more broad range of species. However, other features are shared not only among their narrow range of species but also a broader range.
What are structures that are anatomically similar because they are inherited from a common ancestor?
Homologous structures are structures, or body features, that are similar in two different species. The structures are similar because they were inherited from a common ancestor. Scientists can examine homologous structures to determine how closely related two species are to each other on the phylogenetic tree of life.
Which of the following pairs of structures is homologous?
Forelimbs of a bat and forelegs of a horse are homologous.
What do homologous structures have in common?
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.
Does human whale and bat belong to a common ancestral group?
…a common ancestor is called homology. The forelimbs of humans, whales, dogs, and bats are homologous....…
What is a homologous structure that humans share with other vertebrates when they are fully grown?
The fact that the structure of the human coccyx so closely resembles that of an animal tail gives scientists reason to link it to a common ancestor between mammals and humans. Due to this link, the mammalian tail and the human coccyx are homologous structures.
