|
Survival of the fittest |
Where individuals in a species have certain attributes or characteristics that can help them survive and therefore reproduce. |

Intentional, human altered breeding. |
Same as selective breedinh |
|
|
Evidence for evolution |
Earth's age Comparitive anatomy Mendels law of inheritance Nucleotides |
|
|
|
Homologous structures |
Same evolutionary origin but differ in structure and function |
Example verterbrate limbs |
|
|
Analogous structures |
Different origins used for the same purpose |
Eg wings of butterfly and bird |
|
|
Punctuated equilibrium |
Evolutionary theory where there are isolated episodes of rapid speciation between long periods of little or no change. |
Also known as acquired variation |
