Answers
1
What birds did Charles Darwin study? Where?
Robins; Canada
Finches; Galapagos islands
He studied turtles; Galapagos islands
Blue birds; The Amazon
2
How does biogeography relate to evolutionary history?
Patterns depict how modern organisms evolved from ancestors
DNA is used to determine a species molecular clock
The study of past and present distribution of organisms
Rocks are not living therefore cannot evolve
3
What is genetic drift?
Random change in allele frequency based on chance
Slow extinction of a species
Chance incidents cause alleles to become more or less common
Evolving in a gradual 'drifting' manor
4
What is the main contribution of Charles Darwin?
Founder of the Darwin Awards
Developed methods of breeding pea plants
The theory of Evolution
Idea of Natural Selection
5
Evolution is...
A change in a population or species over time
The way a person changes their sleep schedule
that organisms could change during their lifetimes
6
Which is not a source of genetic recombination
Genetic Recombination
Lateral gene transfer
Polygenic traits
Mutations
7
What is a molecular clock?
Using DNA to estimate the amount of time since species split
A clock made of atoms
Amount of time it takes a molecule to break down
How long it takes a molecule to form
8
Hardy-Wheinburg principle
Allele frequency will stay the same unless a factor changes
The head of school
9
What is the name of the book Darwin published?
Origin of the Species
Darwin: A Theory
Natural Selection
Jurassic World
10
Bottle neck effect
A sharp decrease in food supply
A term meaning "to turn all the way around"
changed allele frequency after large decrease of population
How the environment is impacted by littering of bottles
11
What types of isolation leads to the formation of new species?
None, a new species cannot be created in isolation.
Reproductive, geographic, behavioral
Reproductive, behavioral, continental, temporal
Reproductive, behavioral, geographic, temporal
12
True or False a gene pool has all the different genes and alleles for each gene in a population
True
False
13
Which is not a factor that can disturb genetic equilibrium
Mutations
Non-random mating
Cellular basis of life
Small population size
14
Survival of the fittest, "fittest" meaning...
The healthiest
The strongest, fastest, smartest organism in its environment
How well and organism can survive in its environment
The strongest
15
What was the name of the ship Darwin traveled on?
SS Tipton
HMS Beagle
Mayflower
HMS Monitor
16
What is speciation?
The evolution of a single species over time
Population of a species in an area
The formation of a new species
Finches.
17
Transpiration is...
When humans involuntarily sweat to warm up
Water is released through the roots of a plant
Water is carried from roots to pores on bottom of leaves
When humans involuntarily sweat to cool down
18
What does Darwin’s mechanism for evolution suggest about living and extinct species?
Everything possesses the exact same DNA
The fittest of a species will be the only survivors.
All species are descended from ancient common ancestors
Natural Selection
19
Define: artificial selection
Choosing to eat artificial foods
Killing off undesirable parts of a species
Intentional reproduction based on desirable traits.
Opposite of Natural Selection
20
Darwin's finches are recognized for their varying...
Mating rituals
Feathers/patterns
Beaks
Intelligence
21
Which is not one of the patterns of biodiversity that Darwin noted?
Related species inhabited different habitats in a local area
Similar species were found all over the globe
Fossils of extinct creatures were similar to living fossils
Animals help other animals
22
What is a way that humans have microevolved?
They are naturally meaner then on the past
They are naturally dumber then in the past
They are naturally taller then in the past
They are naturally fatter then in the past
23
True or False Lamarck thought organisms could change by selectively using parts of their bodies
False
True
24
Adaptation is...
The process of making DNA into RNA
Natural selection
Heritable characteristic that increases ability to survive
A trait of water that allows a hydrogen to attach to another
25
Where do new genes come from?
Introns are randomly pieced together and added to zygotes
DNA polymerase II produces organizes new genes
Through duplication and modification of existing genes
evolution.
26
Vestigial structure
Way that organs are organized in an organism
Lining of the stomach
Structure from ancestors that has lost its original function
The structure of a vestibule
27
Homologous vs analogous structure
Matching chromosomes; word opposite in meaning
Same structure; same function different structure
Same genetic info; opposite genetic info
Same function; same structure different function
28
Where are the Galapagos islands located?
West of the coast of Ecuador
Off the coast of China
East coast of Africa
East of the coast of Brazil
29
Founders effect
Change in phenotypes of a population
The impact of the founding fathers
Change in allele frequency as a result of migration
30
What is the purpose of Hox genes?
To eat away skin cells between fingers in development
To code for hamstrings
Determine what part of an embryo develops into limbs, etc.
To determine gender in an embryo
