Which of the following ideas is supported by Darwin’s observation of local variation among tortoises and finches in the Galápagos Islands?
artificial selection
acquired characteristics
adaptation
tendency towards perfection
Which statement is part of Darwin’s theory of evolution by natural selection?
More offspring are produced than can possibly survive.
The number of offspring is not related to fitness.
The organisms that are the fittest are always largest and strongest.
Acquired characteristics that are inherited are the cause of evolution.
change in a DNA sequence that affects genetic information
transformation
mutation
fitness
Based on the partial gene segments shown, which pair of animals are genetically most closely related and therefore most recently diverged from their common ancestor?
Chimpanzee and Mouse
Rat and Chimpanzee
Rat and Mouse
Gorilla and Chimpanzee
Which rock layer contains the newest fossils?
F
E
D
C
B
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.
all eat the same type of food.
acquired traits through use and disuse.
descended from a common ancestor.
Images of the embryo and adult stages of three different organisms are shown.
Which of the following is the best conclusion that can be drawn from this evidence?
Having similar embryos indicates that these organisms eat the same types of food.
Having similar embryos indicates that these organisms share a recent common ancestor.
Having similar embryos indicates that these organisms live in a similar environment.
Having similar embryos indicates that a certain protein controls how many legs the adult organisms will have.
If a new trait DOES help an organism survive, what may happen to it?
It dies and its DNA is not passed on
It changes its traits to adapt and survive
It survives and its DNA is passed on
In the table shown, the DNA found in five primate species was compared to the DNA found in humans. The number of sequence differences was recorded. Based on the data in this table, what inference could you make about these species compared to humans?
Lemurs are most like humans.
None of the species are similar to humans.
Gorillas are most like humans.
Only the lemur differs from humans in any way.
Common ancestry relates to evolution because
evolution only happens when there are common ancestors.
evolution can never take place with common ancestors.
Common ancestors make evolution happen more quickly.
the more two organisms have in common, the more recent is their common ancestor during their evolution.
The same species lives in the same area and have different appearances. What term can be used to describe this?
overpopulation
extinction
population
variation
According to the law of superposition, the oldest fossils are found
At the top of the rock layers
In the middle of the rock layers
Near the bottom of the rock layers
Somewhat near the surface
What is reproductive success?
The ability to reproduce.
The ability to not reproduce.
The ability to produce healthy offspring that survive.
The ability to find a mate.
Select ALL the parts of Natural Selection.
overproduction
variation
competition
evolution
selection
What happens to new traits that HELP organisms survive over time?
They become MORE COMMON
They are EQUALLY COMMON
They become LESS COMMON
Which is the best evidence listed for the theory of evolution
fossil record
numerical data
climate change
religious information
Which statement best explains adaptations in context of the Theory of Evolution.
adaptations are critical to the survival of a species by providing ways to adjust
adaptations are when an organism changes is environment to make it easier to live
adaptations allow a single surviving organism to choose its traits and then reproduce
adaptations allow organisms to learn how to survive in any environment
Some scientist think that the dinosaurs went extinct because of an asteroid strike which changed the Earth's climate; other's think that volcanic eruptions changed the climate and caused the extinction of the dinosaurs.
What do these have in common?
both suggest climate change led to artificial selection
both suggest that dinosaurs evolved too quickly after a disaster
both suggest particles from the sky buried the dinosaurs
both suggest that dinosaurs were unable to adapt to climate change
The picture shows the fossil of Archaeopteryx. Does this fossil support the theory of evolution?
yes, because it is a complete fossil and only complete fossils can be used to prove the theory of evolution
yes, because it shows evidence of feathers, indicating that it might be a distant relative of birds
no, because it is so different that it cannot be compared to any modern day organism
no, because it dates back more than one hundred million years ago beyond the scope of dating techniques
Which of the following is a correct statement about the relationship between natural selection and evolution
Natural selection results from evolution.
Natural selection is the mechanism of evolution.
Natural selection includes evolution as a part of it.
Natural selection and evolution are the same thing.
