1. similarity in structure between parts of different organisms due to evolutionary origin from a common ancestor
Usage: biology
2. similarity in structure or position
Usage: general scientific use
3. a branch of mathematics dealing with topological properties that remain unchanged under continuous deformations
Usage: mathematics; topology

Examples

• The homology between human arms and bird wings shows their common evolutionary origin.
• Scientists study homology to understand relationships between different species.
• The bone structure demonstrates clear homology across mammalian species.
• Homology in mathematics helps classify geometric shapes.
• The researcher identified homology between the fossil and modern specimens.
• Understanding homology is crucial for evolutionary biology studies.
