15
Q

Systematics

A

Organisms are named and grouped according to their evolutionary relationships

16
Q

Who was Carolus Linnaeus?

A

A taxonomists who paved the way for a common scientific language of naming species with binomial nomenclature.

17
Q

Binomial nomenclature

A

Each species is assigned a two part scientific genus, and species

18
Q

Genus

A

A group of closely related species

19
Q

Species

A

A group of similar organisms that can breed and produce fertile offspring

20
Q

What is the species name a description of?

A

The organisms habitat, or important trait

21
Q

What are the rules to follow when writing the scientific name of an organism?

A
  1. Scientific name (italics) (cursive)
  2. The generic genus must have a capital letter
  3. The abbreviation sp is used when the specific name is unknown
  4. The scientific name MUST be written in full when it is first used
22
Q

Taxon

A

A group or level of organization

23
Q

How many taxons are there?

24
Family
A group of closely related genera, sharing many characteristics
25
Order
Taxon composed of similar families
26
Class
Taxon composed of similar orders
27
Phylum
Taxon composed of closely related classes
28
Kingdom
Largest taxonomic group consisting of closely related phyla
29
What are the seven different taxons?
1. Kingdom 2. Genus 3. Family 4. Order 5. Class 6. Phylum 7. Species
30
Dichotomous key
An identification guide to help all people identify organisms according to their scientific names
31
Evolutionary classification
Grouping organisms in taxons based on their evolution history
32
Cladogram
Diagram that shows evolutionary relationships among group of organisms.
33
What does the Cladogram tell the scientists?
That the closer two groups share a more recent ancestor than groups farther away
34
Derived character
A trait that makes all of the organisms after that point on the Cladogram different from the organisms below that point on the Cladogram
35
Domains
A larger more inclusive category than kingdom
36
Domain bacteria
Composed of Eubacteria
37
Domain Archaea
Archaebacteria
38
Domain Eukarya
Protista, fungi, Plantae, Animalia
