Aristotle’s Classification System(Only two groups of living things. Can you guess what they were?)
Plants Animals (Which he divided into three subgroups. Can you guess what they were?
Those that fly Those that walk Those that swim

Aristotle’s classification system was simple, but it lasted for about
2000 years!
And then,along came…

Carol__ Linnae__ (1707-1778)
Swedish scientist
Fascinating man
Agreed with Aristotle (plants and animals), but grouped them further, based on their form.
Considered the Father of Modern Taxonomy.

Linnae also invented the way we give scientific names to organisms.
Look at some scientific names (“binomials”). What do you notice about how they are written?
Canis familiaris
Felis domesticus
Homo sapiens
Mephitis mephitis
Quercus alba
Acer saccharum
Mus musculus
Equus zebra
Usually Latin
Two names (genus and species) “binomials”
Only capitalize first letter of the genus
Italics or underlined

Carol was a very interesting fellow.(Click on the image for a short video on Linnaeus.)
He even changed his own name to sound like it was Latin!
(“Carolus Linnaeus”)
Personally named over 13,000 species.
Made his famous “garden clock.”
