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.

Homologies - Understanding Evolution
Homologies can be identified by comparing the anatomies of different living things, looking at cellular similarities, studying embryological development, and studying vestigial structures within individual organisms.

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 similarities caused by shared ancestry between two structures or genes from distinct 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.

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.

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.

7.13C: Homologs, Orthologs, and Paralogs - Biology LibreTexts
In genetics, the term “homolog” is used both to refer to a homologous protein and to the gene ( DNA sequence) encoding it. As with anatomical structures, homology between protein or DNA sequences is defined in terms of shared ancestry.

Homologies: Cellular/molecular evidence - Understanding Evolution
At the cellular and molecular levels, all living things are fundamentally alike. These basic similarities are most easily explained by evolution: life shares a common ancestor.
