WorksheetsLesson 3: Darwin's Theory of Evolution Through Natural Selection
Total questions: 34
Worksheet time: 45mins
The gradual change in species over time is...
Evolution
Nucleotide
Adaptation
Natural Selection
The struggle for existence against other members of an organisms species is
Competition
Natural Selection
gene flow
genetic drift
How does natural selection drive evolution?
It does not; natural selection and evolution are entirely separate processes.
Before they can reproduce, individuals must adapt certain traits through natural selection.
Within a generation, natural selection causes populations to eliminate unfavorable traits.
Over time, natural selection causes living populations to evolve environmental adaptations.
What question regarding the traits of Galápagos finches did Darwin consider for many years?
How had an original finch been modified in different ways for different purposes?
Why were these finch species only found in certain parts of the world?
Why couldn’t finches with narrow beaks consume a diet of seeds in addition to insects?
How did this great variety of finch species survive in the same ecosystem?
On what group of islands did Darwin make his most famous observations?
Galapagos
Madagascar
Hawaii
Beagle
What led Darwin to his idea of natural selection?
Individuals had certain traits that made them more successful.
The Galápagos finches had a unique method of adaptation.
Ecosystems with limited resources fostered great biodiversity.
All of the above.
A group of individuals of the same species that live and reproduce in the same place is called
a community.
a population.
an organization.
a civilization.
Individuals in a population are not all
compatible.
identical.
the same species.
living in one ecosystem.
What does genetic variation describe?
similarities in the inherited traits of different individuals
similarities between species in an ecosystem
differences in the inherited traits of different individuals
differences between various species’ mating preferences
When individuals with certain inherited traits are more likely to survive and reproduce than those with less favorable traits, ______ occurs.
genetic selection
natural selection
favored survival
struggle for existence
How does natural selection drive evolution?
It does not; natural selection and evolution are entirely separate processes.
Before they can reproduce, individuals must adapt certain traits through natural selection.
Within a generation, natural selection causes populations to eliminate unfavorable traits.
Over time, natural selection causes living populations to evolve environmental adaptations.
Which statement about adaptations is true?
They are inherited.
They are developed quickly.
They cannot change over time.
They are the same in every species.
Although he was initially sent to medical school, what was Charles Darwin's true passion?
arts
mathematics
nature
writing
What was the primary goal of the Beagle's voyage?
to transport passengers to North America
to search for new forms of medicine
to map the coast of South America
to explore the Southern hemisphere
What was Darwin's designated role on the Beagle?
documenting the journey as the ship's journalist
studying animals and plants as the ship's naturalist
providing food for the crew as the ship's cook
taking care of the passengers as the ship's surgeon
What argument did geologist Charles Lyell make that would later become important to Darwin’s work in South America?
The Earth’s age was impossible to calculate.
Some of Earth’s features resulted from gradual processes over long time periods.
Earth’s features were created within a short period of time and have not yet changed.
Land formations in South America cannot be found elsewhere in the world.
What did Darwin find especially remarkable about species of the Galápagos Islands?
All of these species were birds.
These species had very little biodiversity.
Darwin could not study these species without the assistance of other naturalists.
Many of these species resembled mainland South American species.
After the Beagle's voyage ended, Darwin spent time thinking about the ______ of Galápagos finches.
beauty
habitats
rarity
traits
What question regarding the traits of Galápagos finches did Darwin consider for many years?
How had an original finch been modified in different ways for different purposes?
Why were these finch species only found in certain parts of the world?
Why couldn’t finches with narrow beaks consume a diet of seeds in addition to insects?
How did this great variety of finch species survive in the same ecosystem?
Darwin used the Galápagos finches as evidence that
traits are not hereditary.
living things change over time.
birds are different than other species.
organisms in a species have no relation to one another.
According to Darwin, ______ in species could result from many ______ over long periods of time.
population growth; births
mating; interactions
big changes; small changes
extinction; deaths
Eventually, Darwin realized that all living things were engaged in a ______ because there were not enough resources for all of them.
genetic ritual
fight to the death
temporary competition
struggle for existence
