Taxonomy |
* the science of classifying organism into groups. * the taxonomist has over 1.5 million different species of organisms to group, with 30,000 to 40,000 more being added each year.
|
|
|
classify |
* to assign an organism to a particular classification group |
|
|
identify |
*to determine the group in which an organism belongs |
|
|
Aristotle |
* based his groupings on observable characteristics artificial classification * had two major grouping plants or animals * had three subparts plants: herbs, shrubs, trees Animals: birds, fish, animals *used for almost 2,000 years |
|
|
Carolus Linnaeus |
*created a new classification system in the mid 1700s * based his system on observable characteristics *made a move delvoped system that is more flexible |
|
|
todays system of classification |
*Uses a classification hierarchy * starts with the broodiest group of classification and works down to the narrow groups * Has seven basic levels: 1. kingdom 2. phylum 3. class 4.order 5. family 6. genus 7. species |
|
|
kingdoms Eubacteria and Aruchebateria |
* cell type: prokaryotic * reproduction asexual |
|
|
kingdom Prostia |
* algae and protozoans * autotrophic and heterotophic * mobile and stationary * unicellullular and colonial * ekuarotic cells that aren't animals plants or fungi |
|
|
Kingdom Fungi |
* eukaryotic * all heterotic * unicelluar an colonial |
|
|
kingdom Plante |
*eukaryotic *all multicellular with true tissue * most autotrophic |
|
|
Kingdom Animalia |
* eukarotic * all multicelluar with true tissues *all herterotrphic |
|
|
Binomial nomenclature |
* A system of naming organisms in which each organism is given a genus and species name.
|
|
|
Genus species names |
* the scientific name of an organism * uses latin because its a dead language, known by scholars, and highly descriptive |
|
|
species |
* A population of organisms that are structurally similar but do have a degree of variation; a group of organisms that interbreed and produce a fertile offspring |
|
|
Problems with the concept |
* artificial characteristics * affected by environment * ignored similarities
|
|
|
Interbreeding |
* asexual reproduction * inability to interbreed in some species |
|
|
Biblical kinds |
* natural grouping of organisms that have the ability to interbreed |
|
|
Baraminology |
* the study of classification based on Biblical kinds |
|
|
Spectation |
* the formation of a new species |
|
|
Isolation |
* results of migration the moving of organisms from one area to another * types: geographic isolation and behavior isolation |
|
|
adaption |
*any inheritable charteristic that gives surveil advantage to organism |
