Classification is

The arrangement of organisms into orderly groups based on their similarities/differences.

Why classify?

Helps to make sense of large # of organisms

Example (not living)– Stores, closets, CDs

History of Classification

Aristotle (Greek) 2000 years ago– Two groups

• Animals• Plants

Modern Classification

Also includes– Fossil studies– Hereditary info– Early stages of development

Phylogeny– The evolutionary history

Scientific Names

Page 17: Classification Classification is The arrangement of organisms into orderly groups based on their similarities/differences.

What’s in a Name? 2 part scientific name- Latin or Greek 1st part

– Genus– Always begins with Capital letter

2nd part– Species– Always begins with lowercase letter

Both parts are underlined or italicized

Page 18: Classification Classification is The arrangement of organisms into orderly groups based on their similarities/differences.

Why do we need scientific names? So scientists from all over the

world know what animal/plant that name refers to– can COMMUNICATE with each other
