1. Chapter 17: The Tree of Life How Do We Classify Organisms

2. There are 1.9 million different identified species (alive and extinct)
How do we group the place where the utensils are place? Draw it in the space below
There are 1.9 million different identified species (alive and extinct)
How can we keep all these organisms in order?

3. Classification
is the method of logically grouping organisms based on some common characteristics
Physical & Structural similarities
Biochemistry– more similar the proteins the more similar the DNA
Evolutionary history

4. Binomial Nomenclature.
Think of the many words you can use to describe something that is really, really good.
Binomial Nomenclature.
Every species is given a two-part scientific name using Latin words
Homo sapiens – that’s us
Canis familiaris – domestic dog
Felis domestica – house cat

5. 8 Major Levels of Classification
Dear King Philip Came Over From Germany Saturday

6. The Taxonomic order:
From the largest, most inclusive group to the smallest, most exclusive, specific taxa.

10. Cladistics Takes an evolutionary look into classification
Cladogram is an evolutionary tree that hypothesizes how species may be related to each other through common ancestors
Clade
Group of species
Derived Characters
Trait that is common to all the species up the cladogram
