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

A

7

24
Q

Family

A

25
Q

Order

A

Taxon composed of similar families

26
Q

Class

Grouping organisms in taxons based on their evolution history

32
Q

Cladogram

A

Diagram that shows evolutionary relationships among group of organisms.

33
Q

What does the Cladogram tell the scientists?

A

That the closer two groups share a more recent ancestor than groups farther away

34
Q

Derived character

A

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
