| science of naming & classifying organisms | taxonomy
🗑

| when taxonomists group species that share common ancestros closer together | biological relationship
🗑
|

| allows taxonomists to organize a lot of data so it is easy to find and understand | classification benefits
🗑
|
||||
| is how scientists know about extinct species and is based on how animals have changed in the past | fossil record
🗑
|
||||
| helps taxonomists show relationship "genetically" among organisms that are not obvious by just observing physical traits | molecular evidence
🗑
|

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.
