binomial nomenclature
2 part format of scientific name of an organism (genus, capitalized and species epithet, lower case)
who developed binomial nomenclature
carolus linnaeus
species
group of related organisms
population
members of same species in one location
viruses
international committee of taxonomy in viruses determines formal name
variants
sequence of differences that may have functional consequences
serotype
differential recognition by immune system
carl worse
greater of tree of life (bacteria, Arcaea, and eukaraya) look alike but different examined molecular data, domain bacteria and domain eukarya
Charles Darwin
founder of evolutionary taxonomy
classification
domain, kingdom, phylum, class, order, family, genus, species (dynamite kindly professors cannot often fail good students)
plantae
multi eukaryotic autotrophic - photosynthesizers
anamania
multi-eukaryotic, heterotrophic consumers
fungi
multi eukaryotic - heterotrophic absorbers
Protista
eukaryotic unit multi
eubacteria
uni prokaryotic
archaebacterial
unicellular prokaryotic
monophyletic groups
common ancestors species and all its descendants
clades
give info about relationships based on descent from common ancestor
shared derived characters
traits shared by clade
synamorphy
characteristic present in an ancestral species and shared exclusively (in more or less modified form) by its evolutionary descendants.
phylogeny
illustration depicting hypothesis of evolutionary history
taxon
named classification unit to which individuals or sets species assigned
topology
branching pattern of a phylogenic tree
homology
the study of likeness
vertebrate forelimbs
used for different functions but have the same arrangement of bones (homologous) colored in the same way are and are labeled on the human arm
analogous
convergent evolution, not shared, not similar
