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.

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.

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.

Homology - Wikipedia

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.

Homologs Explained: Genes, Structures, and Analogs
Recognizing homologous features allows scientists to trace lineage and reconstruct evolutionary descent. The presence of homologous elements across diverse species provides evidence for the deep connections that link living organisms through geological time.

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.

What Is Homology in Biology and Why Does It Matter?
Homology is the term biologists use when two structures, genes, or traits in different species exist because they were inherited from the same common ancestor.
