Definition
| The science of classifying organisms into into diffrent categories |
|
|
Term
|
Definition
| A system of naming species that uses a double name such as Homo Sapiens. The first name alone names the genus: both names used together name the species |
|
|
Term
|
Definition
| A group of closely related species |

Term
|
Definition
A group of organism at any level of the taxonomic hierarchy

Definition
| Major division of a class, consisiting of closely related families |

Term
|
Definition
| Major division of a kingdom, consisting of closely related classes; represents a basic body plan |
|

Term
|
Definition
| Refers to the evolutionary history of species |
|
|
Term
|
Definition
| Similarities due to inheritance from a common ancestor |
|
|
Term
|
Definition
| A comparison of two different animals may reveal many anatomical correspondences |
|
|
Term
|
Definition
| Referring to similarities that are not homologous. Homoplasy can arise for parellelism, converence, analogy, and chance |
|
|
Term
|
Definition
| Nonhomologous similarities in diffrent evolutionary lines |
|
|
Term
|
Definition
| Homo plastic similarities found in related species that did not exist in the common ancestor; however, the common ancestor provided initial commonalities that gave direction to the evolution of the similarities |
|
|
Term
|
Definition
| Structures that are superficially similar and serve similar funtions but have no common evolutionary relationship |
|
|
Term
|
Definition
| A theory of classification that differentiates between shared ancestral and shared derived features |
|
|
Term
|
Definition
| A group of species with a common evolutionary ancestry |
|
|
Term
|
Definition
| Species used in a cladistic analysis that are closely related to the species being studied and are used to differentiate between shared derived and ancestral derived features |
|
|
Term
| Shared derived (synapomorphic) feature |
|
Definition
| A recenctly appearing homology that is shared by a relatively small group of closely related taxa |
|
|
Term
| Shared ancestral (Symplesiomorphic) feature |
|
Definition
| Compared with shared derived features, a homology that did not appear as recently and is therefore shared by a larger group of species |
|
|
Term
| Uniquely derived (autapomorphic) feature |
|
Definition
| A feature that is unique to a particular species |
|
|
Term
|
Definition
| A graphic representation of the species, or other taxa, being studied, based on cladistic analysis |

Definition
A Chordate is a animal with a notochord. They do not need to have spines- they just need to have a spinal cord. Fish, Reptiles, Mammals, Birds, and Amphibians are all members of the Chordate phylum. There are also invertabrates closley related to these members of the Chordate phylum that are Chordates

Term
|
Definition
| Structures that filter out food particles in nonvertebrates chordates and are used for breathing in some vertebrates |
|
|
Term
|
Definition
| Members of the subphylum Vertebrata; possess a bony spine or vertebral column |
|

Term
|
Definition
| Elements supporting the gill slits in nonvertebrate chordates and some vertebrates |

| An egg with a shell and several internal membranes, which made reprodution on land possible |
|
|
Term
|
Definition
Any of various warm-blooded vertebrate animals of the class Mammalia, including humans, characterized by a covering of hair on the skin and, in the female, milk-producing mammary glands for nourishing the young
