Fossil Record
- Show preserved organisms over time
- (family tree) created from a fossil record
- The study of developing embryos

Comparative Anatomy
- Comparing the anatomy of one to that of another

Molecular Biology
- Species that share a common ancestor and have few amino sequence differences
Amino Acid Sequence
- The way amino acids are paired to make a series of proteins
- Geographic isolation prevent the exchange of genes between population and is the first step leading to the formation of a new species
Divergent Evolution
- Two or more species evolved from a common ancestor
Adaptive Radiation
- Rapid divergent evolution
Acquired Traits
- Traits that are given according to the use and disuse of these traits
Concept of Gradualism
- profound change is the cumulative product of slow but continuous processes, often contrasted with catastrophe
Acquired Characteristics
- Characteristics that were acquired then pated down onto offspring
Punctuated Equilibrium
- Things stay the way they are and then they rapidly change. So they stay this way for awhile, and then they change again
