What is systematics? |
the branch of biology that deals with classification and nomenclature; taxonomy. |
|
|
What is a taxon? |
a taxonomic group of any rank, such as a species, family, or class. |
|
|
Who is Carl Linneaus and what did he do? |
His system for naming, ranking, and classifying organisms is still in wide use today with many changes. |
|
|
What is nomenclature? |
the devising or choosing of names for things, especially in a science or other discipline. |
|
|
What is the order of taxonomic categories? |
There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, species. |
|
|
What is the standard for naming new species? |
The ICZN does not usually deal with the routine descriptions, naming and publishing of new species, this is a practical matter for taxonomists however the ICZN does define the rules which create the framework under which this can be undertaken. |
|
|
What is binomial nomenclature? |
the system of nomenclature in which two terms are used to denote a species of living organism, the first one indicating the genus and the second the specific epithet. |
|
|
How is binomial nomenclature written? What language? |
Writing binomial names. By tradition, the binomial names of species are usually typeset in italics; for example, Homo sapiens |
|
|
What does polyphyletic mean? |
derived from more than one common evolutionary ancestor or ancestral group and therefore not suitable for placing in the same taxon. |
|
|
How many Domains are there? |
According to the Woese system, introduced in 1990, the tree of life consists of three domains: Archaea (a term which Woese created), Bacteria, and Eukarya. The first two are all prokaryotic microorganisms, or single-celled organisms whose cells have no nucleus. |
|
|
What eukaryotic organisms are single celled and have their own kingdom? |
animal, plant, fungi, protist, eubacteria, archaeobacteriav |
|
|
What eukaryotic organisms are autotrophic and have their own kingdom? |
These organisms are a part of the kingdom Archaebacteria (otherwise known as just "Archaea"), which consists of bacteria. As their name implies, archaebacteria live in |
|
|
What physical characteristics of cells separate plant and animal cells? |
is the identification and naming of species and the arrangement of them into biological classes |
|
|
What is evolutionary systematics? |
classification, or Darwinian classification, and Synthetic systematics, is a way to determine natural relationships of organisms by studying a group in detail and comparing degree of similarity. |
|
|
What does homology mean? |
the quality or condition of being homologous. |
|
|
What does phylogeny mean? |
the branch of biology that deals with phylogenesis. |
|
|
Draw a sketch of the fox from the PPT that indicated anatomical direction. Ex. Ventral,Dorasal ect. |
|
|
|
What is a dichotomous key and what is it used for? |
A dichotomous key is a tool that allows the user to determine the identity of items in the natural world, such as trees, wildflowers, mammals, reptiles, rocks, and fish. Keys consist of a series of choices that lead the user to the correct name of a given item. "Dichotomous" means "divided into two parts". |
|
|
What is a cladogram and what is it used for? |
A branching treelike diagram used to illustrate evolutionary (phylogenetic) relationships among organisms. Each node, or point of divergence, has two branching lines of descendance, indicating evolutionary divergence from a common ancestor. |
|
|
Describe the two methods used to classify animals, physical characteristics/genetics. |
The term "genetic characteristics" can refer to a genotype, which is the specific DNA sequence that codes for a trait, or a phenotype, which is how the specific DNA sequence manifests itself in the organism -- often, but not always, the phenotype is how the organism looks. |
