Vestigial Structure
|
- Structure reduced in size and function and is considered evidence of that organisms evolutionary past
|
|
|
Analogous Structures
|
- Similar functions but different structure ~Ex: Insect wings and Bird wings
|
|
|

|
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
|
|
|
Biogeography
|
- 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
