||||
|---|---|---|---|---|---|
| Mutation | any change in the sequence of the bases in DNA
🗑
|
||||
| evolution | the process of changing over time
🗑
|
||||
| natural selection | nature picks the best traits; more helpful traits become more frequent in a population when there are more offspring than resources
🗑
|
||||
| fitness | the ability to survive to reproduce and pass on your genes
🗑
|
||||
| analogous structures | body parts with similar function but not similar structure; they do not point to a recent commom ancestor
🗑
|
||||
| homologous structures | body parts with similar structure that point to a commom ancestor
🗑
|
||||
| stasis or genetic equillibrium | genetic stability, staying the same genetically
🗑
|
||||
| punctuated equilibrium | short periods of rapid change
🗑
|
||||
| mimicry | One species evolves traits to resemble another species
🗑
|
||||
| recombination | an offspring's genetic information is a mix of the mother and father
🗑
|
||||
| adaptation | an existing inheritable trait that allows an organism to better survive under current conditions
🗑
|
||||
| vestigial structure | anatomic structure that no longer functions in modern organism but served a function in ancestor; it is evidence of evolution
🗑
|
||||
| biogeography | study of where modern and ancestral organisms lived
🗑
|
||||
| Molecular Record | comparing DNA, RNA, or proteins to identify # of differences in order to determine relatedness
🗑
|
||||
| Molecular Clock | uses mutation rates in DNA to determine the amount of time that two species have been evolving independently
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
