Primate Trait

Definition

a) INcreased parental investment

b) increased dependence on learned behavior

c) primates learn how to mother

Term
Relative Dating Techniques
Definition
Using Stratigraphy to estimate age in realtion to something else
Term
Calibrated Relative Dating Techniques
Definition

Use geological processes that can be calibratefd to a chronological age if certain condtions are known

ex. Paleomagnetism

Term
Chronometric Dating Techniques
Definition
Uses a clock to measure age in years before present
Term
Radiometric Dating
Definition

Radiocarbon

Potassium-Argon

Argon/Argon

Fission Track

Cosmogenic Radionuclides

U Series

Electron Tap

 

Term
Principles of Stratigraphy
Definition

Superposition-older layers are covered by newer layers

 

Faunal Succession-Once a species goes extinct it does not reappear again

Term
Speciation
Definition
An lineage splitting event that produces 2 or more different species
Term
Allopatric Speciation
Definition

a) produced by geographic isolation

b) this is produced by cladogenesis

c)Interruption of Gene Flow (reproduction)

Term
Parapatric Speciaton
Definition

a) 2 populations have divergesd without geographic isolation

b) partial reproductive isolation

c) hybridf zone that could potentially create 3rd species

d) New Niche entered

SOmething happened that they had to go outside their normal habitat

Over time they develop differently to adapt to their new environment

Term
Symatric Speciation
Definition

a) utlization of different ecological systems in same geographic range

b) no geographic isolation

c)change in food and habitat (resources)

Term
Anogenesis
Definition

a) Time is the isolater

b) When one species evolves into another over time

 

 

All speciaiton mode is Phletic Gradualism

Slow and steady

Term

Callitrichidae
