Forefathers of Classification
• Aristotle (Greece): the first person to realize that all living things should be organized
• Carl Linneaus (17th century): 1st person to classify living things in a scientific way
• Charles Darwin (18th century): developed a classification system based on evolution
Grouping of Living Things by Domain
