Describe the difference between microevolution and macroevolution. 

Microevolution- when changes affect specific genes and occur over shorter time scales

Macroevolution- large-scale changes that occur over extended periods of time that can form new species or groups 

100

Who created the current hierarchy of taxonomy? 

Carl Linnaeus 

100

The amount of extinctions recorded 

What is 5? 

100

The definition of a cladogram

A visual representation of evolutionary relationships using lines, animals and derived traits. 

100

Define adaptation. 

Changes over time that allow species to survive. 
200

Structures that have the same function but different structures. 


Analogous Structures 

200

Who is known as the "father of Evolutionary Theory"? 

Charles Darwin

200

The organisms that survived the Ordovician- Silurian Extinction

What are BONY FISHES? 

200

Which trait is shared by both reptiles and birds? 


The egg shell

200

Define "fitness"

The ability to survive and reproduce 

300

Same structure, different function 


Homologous structures 

300

What is the most specific "rung" of the taxonomy ladder? 

Species 

300

The % of species that died at the end of the Permian - Triassic Extinction. 

96%

300

Which is the closest relative to the crocodile?  

The bird

300

Does natural selection act upon phenotypes or genotypes. Explain. 

Phenotypes- selection occurs on physical features, not actual genes. 

400

Structures that used to have a function but no longer serve a purpose.

Vestigial Structures 

400

What is the broadest "rung" of the taxonomy ladder? 

Domain 

400

The organisms that are direct descendants of the now extinct dinosaurs. 

Birds

400

What trait do the Elasmobranchs possess that the lampreys do not? 


JAWS

400

Describe the difference between R-selected and K-selected species. Give examples for full credit. 

R-selected - Lots of offspring, short life spans (ex. rabbits, bacteria, bumblebees) 

K-selected- Fewer offspring, typically longer life spans (elephants, humans, crocodiles, sharks) 

500

Compare a bat, moth and bird wing.  Describe their analogous and homologous features. 

Bats and birds= homologous features

Moth and bats= analogous features 

500

What is the suffix of words indicating species belong to the same family? 

-idae

500

The cause of the Cretaceous - Tertiary Extinction 

An asteroid hit the Yucatan peninsula in Mexico causing the atmosphere to heat up, smoke and dust blocked the sunlight which led to no photosynthesis and an eventual collapse of almost all food webs. 

500

What did the tetrapods evolve that these groups of fishes did not have? 


Limbs used for terrestrial locomotion 

500

Describe the legacy of Francis Galton's Eugenics movement. 

Let to scientific racism and affects people today due to policies and laws that were written in the 1900s.
