Homology (biology) - Wikipedia
In biology, homology is similarity in anatomical structures or genes between organisms of different taxa due to shared ancestry, regardless of current functional differences.

Homology | Morphology, Comparative Anatomy & Genetics | Britannica
homology, in biology, similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor. Homology is contrasted with analogy, which is a functional similarity of structure based not upon common evolutionary origins but upon mere similarity of use.

Homology - Definition and Examples - Biology Online Dictionary
In biology, homology refers to the similarity of the structure, physiology, or development of various species of other organisms as a result of their shared evolutionary parent. It plays a huge part in evolutionary biology.

Examples of Homology in Animals and Plants | YourDictionary
Homology refers to two things that have an equivalent role or relationship. Homology is important in comparative biology since it makes it possible to determine if two different animals or plants share a common ancestor.

7.13C: Homologs, Orthologs, and Paralogs - Biology LibreTexts
Homology forms the basis of organization for comparative biology. A homologous trait is often called a homolog (also spelled homologue). In genetics, the term “homolog” is used both to refer to a homologous protein and to the gene ( DNA sequence) encoding it.

Homology (biology) - New World Encyclopedia
In biology, homology is commonly defined as any similarity between structures of organisms in different taxa that derives from similar structures in their shared ancestry. Examples of homology occur at different levels of organization.

What is homology in biology? - California Learning Resource Network
Homology refers to the presence of similar structures, DNA sequences, or genes between different organisms, indicating a common ancestry. This concept was first introduced by Charles Darwin in his groundbreaking book "On the Origin of Species" in 1859.

Essay: Homology | Embryo Project Encyclopedia
Homology is a central concept of comparative and evolutionary biology, referring to the presence of the same bodily parts (e.g., morphological structures) in different species.

HOMOLOGY Definition & Meaning - Merriam-Webster
The similarity of a structure or function of parts of different origins based on their descent from a common evolutionary ancestor is homology. Analogy, by contrast, is a functional similarity of structure that is based on mere similarity of use.
