Structural and Functional Evidence for Common Ancestry of Eukaryotes

Eukaryotes, organisms whose cells contain membrane-bound organelles and a defined nucleus, share several structural and functional features that provide evidence for their common ancestry. These shared characteristics highlight the evolutionary relationships among eukaryotic organisms, supporting the idea that they all descend from a common ancestor.
