concepts
systematics
understand each evolutionary lines
nomenclature
system of giving names that reflects their relationships accurately
phylogeny
evolutionary history of each member of the group
natural system of classification
system which closely related organisms are classified together and assigning plant names on the basis of phylogenetic relationships
Levels of taxonomic categories
species
set of individuals closely related by descent from a common ancestors
genus
closely related species which are grouped together
development of concepts of evolution and classifiction
binomial system of nomenclature
combines two names into one to give all species unique scientific names. The first part of a scientific name is called the genus. The second part of a species name is the specific epithet. Species are also organized into higher levels of classification.
inheritance of acquired characteristics
an organism can pass on characteristics that it has acquired through use or disuse during its lifetime to its offspring
