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 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.

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.

What is Homology? | National Center for Science Education
These similarities are homologies, because bats and humans share a common ancestor. Pterosaur, bat, and bird wings: Pterosaurs, bats and birds produced wings with functionally similar shapes from a homologous organ (the forelimb) in three distinct ways.

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.
