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 & 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.

What Is a Homologue? A Definition With Examples
In biology, a homologue refers to a feature or structure in different species that is similar because it was inherited from a shared common ancestor. These shared features suggest a fundamental underlying blueprint passed down through generations.

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.

3.23: Homologies provide evidence for a common ancestor
Detailed analyses of many different types of organisms reveals the presence of a common molecular signature that strongly suggests that all living organisms share large numbers of homologies, which implies that they are closely related - they share a common ancestor.

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.

Homology - Simple English Wikipedia, the free encyclopedia
A homologous[1] trait is any characteristic which is derived by evolution from a common ancestor. This is contrasted to analogous traits: similarities between organisms that were evolved separately.

Homologies: Cellular/molecular evidence - Understanding Evolution
But genetic homologies extend far beyond such closely related twigs on the tree of life. For example, 70% of human genes are homologous to genes found in acorn worms – eyeless marine worms that usually make their living filtering bits of food out of the water or mud.
