Charles Darwin’s observation that finches of different species on the Galápagos Islands have many similar physical characteristics supports the hypothesis that these finches
have the ability to interbreed.
acquired traits through use and disuse.
all eat the same type of food.
descended from a common ancestor.
How well an organism can survive and reproduce in its environment
fossil
fitness
inherited trait
Inherited characteristic that increases an organism's chance of survival
adaptation
evolution
fitness
Evolution is called a theory because
we are not sure if it is true
there's not enough evidence yet
scientific theories are supported by a large amount of evidence
none of these is true
What is is the study of how and why plants and animals live where they do?
Evolution
Adaptive Radiation
Biogeography
Biogeology
_________________ show clear changes in an organism over time, the environment organisms lived in, the time period the organism lived in, and where the organism lived.
DNA
Vestigial structures
Fossils
Homologous structures
What type of evidence is represented in the picture above:
Fossils
Vestigial Structures
DNA
Homologous Structures
Does the presence of homologous structures in genetically different animals suggest common ancestry?
Yes
No
A category of structures that have a similar function, but are structurally different.
Homologous structures
Analogous structures
Vestigial structures
Common core structures
A type of structure that is physically present, but does not seem to serve a significant function for an organism.
Homologous structure
Analogous structure
Vestigial structure
Standard structure
What type of evidence are shown in the picture above?
Fossils
Embryology
Homologous Structures
Vestigial Structures
What type of evidence is shown in the image above?
Fossils
Vestigial structures
Homologous Structures
DNA
According to this data, the unknown bacterial species is most closely related to:
Species I
Species II
Species III
Species IV
Define population
A group of individuals of the different species that live in the same area and and not able to interbreed sexually
A group of individuals of the same species that live in the same area and unable to interbreed sexually
A group of individuals of the same species that live in the same area and able to interbreed sexually, producing fertile offsprings
Gene pool
Total number of alleles of the genes that are present in a population of a particular species of organism at a given time
The condition of a population in which allele and genotype frequencies remain constant from one generation to the next
The number of phenotypes present in a population of a species at a given time
Fossil records show that black bears increased in size during the Ice Age and decreased in size with warmer temperatures. What type of selection do these changes in size represent?
Allopatric
Directional
Disruptive
Stabilizing
Babies birth weight is an example of
Disruptive selection
Adaptive radiation
Stabilizing selection
Directional selection
The graph shows variations in beak size for the bird Geospiza fortis on an island in the Galápagos archipelago. What evidence from the graph indicates that disruptive selection is occurring?
An intermediate (medium) beak size is less common.
Median beak size is the most common.
Smaller beaks are favoured.
Larger beaks are favoured.
Allele frequencies in a gene pool do not change, this is
random change
random genetic make up
genetic equilibrium
punctuated equilibrium
What conditions will lead to evolution? (hint: use your hand mnemonic)
Large Populations
Random Mating
Mutations
No movement in or out of population
Natural Selection
The formation of new species is called
Speciation
Evolution
Natural selection
Mutations
Which of the following does NOT lead to reproductive isolation
Behavioural isolation
Competitive isolation
Geographic isolation
Temporal isolation
An example of behavioural isolation
Toads that mate at different times of the year
Plants that have separate pollination times
Birds that have specific songs
Turtles that are separated by a mountain
Who is the closest relative to the birds?
crocodiles
sharks
fish
amphibians
How old is the earth?
2.5 million years
4.6 billion years
1.5 billion years
4.6 million years
How many mass extinctions has the earth been through?
3
1
5
8
Mass extinction would most likely result from which of the following events?
A disease kills off a single species of predator within an ecosystem
A wildfire burns a national park
Global temperatures drop several degrees after several massive volcanic eruptions
A massive earthquake strikes North America
A single species that has evolved into several different forms that live in different ways (have different niches) has undergone
Punctuated equilibrium
Adaptive radiation
co-evolution
Mass extinction
A process by which two species evolve in response to changes in each other over time is
Coevolution
Convergent Evolution
Macroevolution
Symbiotic Evolution
