Taxonomy - ANSWER The branch of biology that is concerned with naming &
classifying organisms
Genus and species - ANSWER What is the two-part scientific name of an
organism?
Genus - ANSWER Group that includes a number of very closely related species
Species - ANSWER Within a genus includes populations of organisms that can
potentially interbreed under natural conditions; two individuals that have the
ability to produce offspring
Underlined or italicized - ANSWER How are scientific names always written?
First letter is always capitalized - ANSWER How is the genus name always
written?
First letter is always lowercase - ANSWER How is the species names always
written?
Biological species concept - ANSWER The species concept that defines species
as "groups of interbreeding natural populations that are reproductively isolated
from other such groups"
Phylogenetic species concept - ANSWER The species concept that defines
species as "smallest diagnosable group that contains all descendants of a single
ancestor"
Homo sapiens - ANSWER What is the scientific name for humans?
