What characteristic did Darwin observe about the finches on the Galapagos Islands?
Their feathers
Genotypes
Their beaks
Their body sizes
The environment around Manchester, England, changed during the Industrial Revolution. How did this change affect peppered moths living in the area?
Natural selection favored moths with dark wings because predators could not see them on the soot-colored trees.
Natural selection favored moths with white wings that were easy for predators to see.
Natural selection favored moths with white wings because predators could not see them on the soot-colored trees.
Natural selection caused moths with white wings to become extinct.
What is this an example of?
diversity of species
variation
vestigial structures
DNA studies
What is a change in an organism that allows for it to survive in its environment?
homologous
vestigial
variation
adaptation
Why did the number of white peppered moths decrease so much by 1895?
they did not blend in with the trees and birds ate them
they tasted better to the birds than the black moths
they were easier to reach on the trees
white moths flew away to find better trees to blend in with
Why do moths and other organism reproduce so many eggs or offspring?
so that their babies can have friends to play with
the more offspring the more likely the offspring will survive
the more offspring the less likely offspring will survive
the more offspring the less competition
What is "survival of the fittest"?
Being the strongest
Being able to survive and produce offspring
Being the smartest
Being able to collect as much resources as possible
Which of the following is a factor in natural selection?
Individuals of species compete with one another to survive.
All species are genetically diverse.
Individuals better able to adapt to changes leave more offspring.
All of the above.
Structures with the same parts but have different functions, suggesting that organisms with a backbone share common ancestry is called…
Not related
Not homologous
Homologous
Young in origin
The presence of pelvic bones in the baleen whale is evidence of which of the following?
Whales can travel on land when necessary.
Whales are developing into animals with four functioning limbs.
Whales have functional legs that are hidden by fat and skin.
Whales evolved from four-legged animals.
organs or skeletal elements of animals and organisms that, by virtue of their similarity, suggest their connection to a common ancestor. These structures do not have to look exactly the same, or have the same function.
Analogous Structure
Homologous Structure
Vestigial Structure
Molecular Homology
Similar embryological development in different organisms indicating a common ancestry or evolutionary origin.
Molecular Homology
Morphology
Adaptation
Embryology
If you know the age of a rock, you know the relative age of the _________________ that was found inside.
sticky tar
fossil
amber
ice
Which of the following can be learned by using the fossil record?
When organisms changed or evolved
when organisms appeared on Earth
when organisms became extinct
All the above
What are the oldest fossils and why?
B, C- because they are closest to the top
A, B- because they are closest to the bottom
They are all the same age- because they are all found on layer 2
A, B- because they are found closest to the top
Geologists use radioactive dating to..
determine the "actual" ages of rock layers.
tell the difference between molds and casts.
tell where one soil horizon ends and the next one begins.
determine the absolute ages of rocks.
In which kind of rock do we usually find a fossil?
sedimentary rock
metamorphic rock
igneous rock
If scientists found this fossil, what could they infer?
what fish are like today
that this fish lacked oxygen
that water once covered the area where this fossil was found
