Regents Biology
What variety! What similarity! Diversity of Life
there are so many different creatures on Earth
why are there differences? Unity of life
all creatures have similarities
common characteristics why are they so alike?

Regents Biology
Organizing the world of organsims The Tree of Life
organize creatures by structure & function how they are built how they live
organize them into groups of closely related creatures

Classification System to organize all living creatures
plants animals microbes etc.

Carolus Linnaeus The Linnean system
proposed in 1700s each species has a
2 part name genus species
Homo sapiens

Regents Biology
Latin binomial 2 part scientific name
Genus — larger group to which organism belongs always capitalized
species — specific name for that organism always lowercase
example: Linnaeus named humans Homo sapiens means “wise man”
— perhaps in a show of hope & optimism
