- When faced with similar environmental demands, distantly related species may evolve to have similar behaviors/physical features

Convergent Evolution

- Structures that may serve the same purpose, but are physically different
- For example, the hand of a human, versus the trunk of an elephant

Analogy

- Physical similarities caused by common ancestry 

Homology in Biology 

As evolution takes place, similar adaptations (physical or behavioral) can be found in different populations through the following: 
- convergent evolution 
- common ancestry
- analogy 

Smith College

- A specific modification (to a certain trait)  that is most likely to be passed on during the process of natural selection, and will be seen in the majority of the population
