Classification. To avoid confusion caused by regional names, biologists use a classification system to group organisms in a logical manner and to assign names. Linnaeus developed the method used to name organisms and group them in a logical manner which gives a universally accepted name.

the scientific name is the universally accepted name given to every species.
Which Similarities Are Most Important?
Early systems of classification grouped organisms together based on visible similarities
Organisms are grouped into categories that represent lines of evolutionary descent, or phylogeny, not just physical similarities
Phylogeny– evolutionary relationships among organisms
A cladogram is a diagram that shows evolutionary relationships among organisms based on shared derived characters.
The American vulture and the Marabou stork are more closely related than the American vulture and the African vulture
Streptococcus bacteria can live in a persons body and cause illnesses like strep throat
Archaea are the most ancient organisms on Earth and they exist in extreme environments
Extremophilic microbes can be found thriving in some of the most hostile environments imaginable —
swimming in near-boiling water
in subzero temperatures
where radiation levels rival nuclear reactors
Acidophile:An organism that grows best at acidic (low) pH values.
Alkaliphile: An organism that grows best at high pH values.
Anaerobe: An organism that can grow in the absence of oxygen.
