1. A correspondence or relationship between organisms or structures that have similar form or function due to common descent or evolutionary origin.
Usage: technical; biology; evolutionary biology
2. In mathematics, a morphism between elliptic curves that is surjective and has finite kernel.
Usage: technical; mathematics; algebraic geometry

Examples

• The isogeny between the forelimbs of humans and bats reveals their shared evolutionary history.
• Biologists study isogeny to understand how different species inherited similar anatomical features.
• The concept of isogeny is central to comparative anatomy and phylogenetic analysis.
• In algebraic geometry, researchers investigate isogenies to classify elliptic curves.
• Isogeny relationships help scientists trace the evolutionary pathways of vertebrate species.
