Chapter 17: History of Classification
Terms in this set (40)
Linnaean system of classification on is based on what?
It is based on the behavioral and morphological similarities and differences among organisums.
In binomial nomenclature, the first part of an organism's name identifies genus, and the second part identifies the_____?
What are the ten part to the Taxonomical catigories.
Domain, Kingdom, Phylome, Class, Order, Family, Genus, and Species
What is typological?
Classification is determined by the comparison of physical characteristics with a type specimen.
What is typologicals' disadvantage?
Classification does not allow for generic variation, such as color, within a species.
What is typologicals' advantages?
Descriptions provide detaild records of physical characteristics of many organisms.
What is biological?
Classification isdetermined by similar characteristics and ability to provide fertile offspring.
What is the biologicals' disadvantage?
Some organisms interbreed occasionally. does not acount for extinct animals
What is biologicals' advantage?
Working definition appllies in most cases
What is phylogenetic?
Classification is determined by evolutionary history
What is phylogenetics' disadvantage?
Evolutiorany histories are nto known for all species.
What is phylogenetics' advantage?
Accounts for extinct species, considers molecular data, and solves problems of other species concepts
What is Harmens Definition for phylogenetic?
When two or more proups diverge from a species steral population each is terned into a new species.
What is biochemical characters?
chromosome banding patterns that show the close relationship among animals
What is molecular clock?
A model that use comparisons of DNA sequences to estimate hpw long species have been evolving independently
What is a Archaea?
Prokaryotes whose cell walls do not contais peptidoglycan
What is bacteria?
Prokaryotes whos cells walls contain peptodoglcan
What is eukarya?
cells with membranebound organells
Organisms are classifiedd into domains according to?
cell type and structure
What organisums are in the same kingdome becasue they cannot form organs?
Which kingdome's organisms have no cell walls?
Why are viruses not included in the biological classification system?
Becasue they have no cells, are not reconciderd cells, and are not living.
goves each species a scientific name that has twoparts
is the grouping of objects
is the grouping of objects or organisums based on a set of criteria
contains related clases also known as phylum
the brodest of all the taxa and contains one or more kingdomes
the next higher taxon, consisting of similar, related genera
contains related families
contains related classes also known as division
a named group of organisums
a doscription of biology primarily concerned with identifying, namign,and classifying species on natural relationchips
to classify a species,scientist often construct patterns of descent, phylogenies, using ingerited features that vary among species
a methid that classifies organisms according to the order tath they diverge from a common ancestor
a branching diogram that reprisents the proposed phylogeny or evolution history of a species or group
a model that is used to compare DNA sequences form two different commong group
the evolutionary history of a species
the species classified in Domain Archaea, are thought to be more ancient then bacteria and yet more closely realated to eukaryote eucesryots
a unicellular of multicellular eukaryote that absorbes nutrients from organic materials in its enviroment
are eukaryote organisms that can be unicellular, colonial, or multicellular
