# 2: Classification of living organisms
Classification: The scientific method of dividing organisms into smaller and
larger groups, on basis of their similarities.
Swedish botanist Carolus Linnaeus is the Father of Systematic Biology.
He believed he could:
• Put every organism into a group (the science of TAXONOMY)
• Give every organism a name (the science of NOMENCLATURE).
Carolus Linnaeus organized taxonomy (1735).
In his BINOMIAL SYSTEM, every living organism has a unique, two-part
name:

• Names are written in Latin, printed in italics.
• The genus always has a capital letter, and the species always has
a small letter.
