The branch of biology that classifies organisms and assigns each organism a universally accepted name
The naming system that assigns a two part scientific name to each organism
Additional level of classification has been added that is essentially a "super kingdom".
Evolutionary history of an organism.
Two structures that are similar in function, but not in structure are considered to be _____ structures. Example: Wings of butterfly and wings of a bird.
