🗑
|

| Kingdom | In a traditional taxonomic system, the highest taxonomic category, which contains a group of similar phyla
🗑
|
||||
| Genus | In a traditional taxonomic system, the category contained with a family and containing species
🗑
|
||||
| Species | A group of organisms that are closely related and can mate to produce fertile offspring; also the level of classification below genus and above subspecies
🗑
|
||||
| Binomial Nomenclature | A system for giving each organism a two-word scientific name that consists of a genus name followed by the species name
🗑
|
||||
| Subspecies | A taxonomic classification below species that groups organisms that live indifferent geographical areas, differ morphologically from other populations of species, but can interbreed with other populations of the species
🗑
|
||||
| Systematics | The classification of living organisms in terms of their natural relationships; it includes describing, naming, and classifying the organisms
🗑
|
||||
| Phylogenetics | The analysis of evolutionary, or ancestral, relationships between taxa
🗑
|
||||
| Phylogenetic Diagram | A branching diagram that models the relationships by ancestry between different species or other taxonomic groups
🗑
|
||||
| Cladistics | A phylogenetic classification system that uses shared, derived characters and ancestry as the sole criterion for grouping taxa
🗑
|
||||
| Shared Character | A feature that is shared by all members or a particular groups of organisms
🗑
|
||||
| Derived Character | A feature that evolved only within a particular taxonomic group
🗑
|
||||
| Clade | A taxonomic grouping that includes only a single ancestor and all of its descendants
🗑
|
||||
| Cladogram | A diagram that is based on patterns of shared, derived traits and that sows the evolutionary relationships between groups of organisms
🗑
|
||||
| Eubacteria | In a traditional taxonomic system, a kingdom that contains all prokaryotes except kingdom that contains all prokaryotes except Kingdom Archaebacteria (Domain Archaea); biologists more recently prefer to classify these organisms as Domain Bacteria

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.
