|
list the major taxonomic catagories from most to least inclusive
|
kingdom, phylum, class, order, family, genus, species
|
king phillip came over for good sex
|
|
|
describe how a species is given a name using binomial nomenclature
|
-genus is the closest group a species belongs to. unique name
-species(specific epithet) refers to one species within each genus |
genus and species
|
|
|
what is a domain?
|
it is the taxonomic category above the kingdom level.
Archaea, Bacteria, Eukarya |
three above
|
|
|
what does the prefix sub- mean on a taxon?
|
lower taxonomic category compared to the one being classified. ex> several suborders would be in a single order
|
lower
|
|
|
what does the prefix super- mean on a taxon?
|
higher taxonomic category compared to the one being classified. ex> one or more orders would be in a super order
|
higher
|
|
|
why is it important to distinguish between homologous and analogous character traits when constructing a phylogeny?
|
homologous traits show how closely different species are related to each other. not always so with analogous traits.
>depends on taxonomic level also |
homologous- siilarities based on shared ancestry
analogous- similarties due to convergent evolution |
|
|
compare sympatric speciation and allopatric speciation
|
allopatric-geographical barriers, exposed to different environments. sympatric-chromosomal changes and nonrandom mating that reduces gene pool
|
allopatric-other homeland
sympatric-same homeland |
|
|
compare cladogenesis and anagenesis
|
in cladogenesis, a new species breaks off from a existing species. in anagenesis, a species changes over time to new species
|
anagenesis-phyletic evolution
cladogenesis-divergent evolution |
|
|
compare homologous structures and analogous structures
|
homologous structures have different functions, same underlying structure. analogous structures have same functions, different structures
|
homo Same Structure
|
|
|
compare convergent and divergent evolution
|
convergent evolution-different organisms come up with similar adaptations. divergent evolution -a new species buds off from a parent species
|
converge-come together
diverge-to separate |
