1. Order in diversity
Access Biology

2. Why did we need to classify organisms in the first place?
Around the world, scientists would discover different plants and animals but there was no way to communicate about them.

3. Biologists use this system to classify organisms by traits.
Taxonomy
Biologists use this system to classify organisms by traits.

5. Binomial Nomenclature
How we name species.
2 words in each name
The first word in the name is the genus
EX Ursas
2nd word in name describes a characteristic
EX matrimus
Ursas matrimus- Polar bear
Ursas has 5 other species of bears.
Matrimus means by the sea

Further way to divide Phylum Starting to see more in common MAMMAL CLASS- drink milk as babies

18. Order- divided into families
Organisms within a family have more in common than with organisms in any classification level above it
A checklist is used to determine order.
Order- divided into families

19. Families are different organisms, same species
522 fish families
136 mammal families
61 amphibian families
57 reptile families
So much in common, they are related

20. Reptile Family

21. Cactus Family
