Classification U.1 L. 1
Taxonomy : identifying animals / classifying them
taxonomy importance : farmers broccoli v. weed, doctors identify disease before treatment
matter to identify things
classification : organize life & indicate evoloutionary relationships
Linnaeus : creator/father of taxonomy, set up a universal system of classification called binomial nomenclature
binomial nomenclature : 2 part naming system, composed of the Genus and Species, ex. tiger = Panthera tigris. always written first name uppercase, second name lowercase, with both of them in italics.
species : a group of organisms that can interbreed in nature and produce fertile offspring
biological species concept : can they interbreed and produce viable offspring ?
morphological species concept : do they look the same ? (definition : branch that deals with structural forms of the species)
phylogenetic species concept : is their DNA the same ? (definition : evolutionary history of a species)
all concepts are used to identify different forms of species
⭐⭐ ranks of taxonomy from broadest to most specific :
domain
kingdom
phylum
class
order
family
genus
species
each rank is called a taxon/taxa (plural)
phylogenetic : reconstructions history based off animals morphology and DNA
phylogenetic tree based on anatomy, physiology and DNA (show time)
tree shows the anatomical, physicological and molecular common characteristics between species
anatomy : structure of organisms, can classify how close species branches are (branch of morphology, includes internal systems)
physiology : biochemical and internal processes (chemical functions of organs)
cladogram : shows the relationship between organisms with ancestors (show characteristics)
clade : group that shares a common ancestor
