Definition: Homologous means having the same evolutionary origin or ancestral structure (e.g., genes or body parts derived from a common ancestor).
Two simple examples:
- The human arm and a whale flipper are homologous — both share the same basic bone arrangement inherited from a common tetrapod ancestor.
- Homologous chromosomes are the paired maternal and paternal chromosomes that carry the same genes in the same order.
One sentence using it:
Although both are used for flight, bird wings and insect wings are not homologous.
