Ecology and Evolution

When would convergent evolution occur?

• When organisms share a common ancestor
• When organisms live in similar environments
• When organisms become increasingly different
• When organisms experience a change in their environment

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures
