Which scientist visited the Galapagos Islands and came up with the theory of natural selection?
Theodor Schwann
Gregor Mendel
Charles Darwin
Rudolf Virchow
Sometimes bones in the front limbs of animals are very similar in structure. What do we call similar bone structures that indicate a common ancestor?
Adaptations
Gradualism
Homologous Structures
Extinction
A physical or behavioral trait that helps an organism survive and reproduce in its environment is called a what?
An adaptation
A response to a stimulus
A mutation
Evolution
What do we call a change in a species over time?
Adaptation
Evolution
Extinction
Environmental influences
Which of the following are correctly identified as evidence of common ancestry?
similar physical features/structures, similar geographic origin, geographic isolation, & reproductive Isolation
similar physical features/structures, similar geographic origin, no geographic barriers, similar embryonic development
different physical features/structures, similar skull structure, radial symmetry, & reproductive isolation
different physical features/structures, similar skull structure, radial symmetry, & identical embryonic development
Fossil records found in different layers of Earth show a sudden change in the features of an organism. This provides evidence of..
fossil validity & mutations
rapid (punctuated) evolution
gradual evolution
reproductive isolation
A species of bird thrived in a very warm environment, but over time their environment experienced a rapid change to a colder climate. This change in climate caused a decrease in the birds with fewer feathers. What is the reasoning for this?
Birds that had fewer feathers were too hot before and could only survive in the new climate
Birds with fewer feathers were best suited for the new environment
Birds with more feathers were best suited for the new environment
Birds with more feathers were too cold before and could only survive in the old climate
How would mimicry be a useful adaptation?
organism could be mistaken and avoided by a predator
organism could blend into the environment to obtain food
Organisms could acquire traits based on their environment
organisms could be easily spooted by predators
Over time, if natural selection occurs,
a favored inherited trait will increase in frequency
the environment will change a favored inherited trait
a favored acquired trait will increase in frequency
the environment will change a favored acquired trait
In an environment that has rocks and snow, animals with the highest fitness would
be red with short fur
be grey/white with long fur
be white with no fur
be red with long fur
In the grasslands of Africa, you expect to find species adapted to grazing on grass. In the Sahara desert, you expect to find species adapted to
going without water for long periods of time (retaining water)
moving between land and water to feed
living in cold, dark environments
building nests in tall trees to avoid predators
Which of the following can lead to development of species?
geographic isolation
reproductive isolation
genetic drift
all the above
A population of beetles (group A) experienced genetic drift and the new group (group B) became geographically isolated. Group A was 50% blue and 50% red, and the new group (B) was 95% blue and 5% red. What can be concluded by this information?
Group B's new environmental conditions favored the blue colored beetles more than red
Group A's environment helped changes acquired traits to be sent to group B
Group B's environmental conditions favored beetle color traits equally and did not contribute color to fitness
Group A's environmental conditions changed the individual beetle color of each organism
Birds on the made up environment of Eastern-Western Island can have short, medium, or long beaks, but birds with medium sized beaks have the highest fitness due to a lack of predators. In 2030, a group of students introduced an invasive species that preyed on birds with medium beaks. Which graph best represents the possible result of shift in trait frequency from this?
Moths in the made up environment of Dawson-land had a green leafy environment. Due to this, moths that had green leafy colored wings blend in with their environment and had the highest fitness in comparison to moths with white color wings. Due to climate change, 50 years ago Dawson-land experienced an extreme snow storm which covered the land in snow that has not melted since. Which graph best represents the possible result of shift in trait frequency from this?
Populations that can successfully inhabit new areas have the ability to
easily adapt to new environments
camouflage to obtain predator habitats once they go extinct
increase resources previously available to the environments
mutate individually to acquire traits to make them successful
According to the image, all the following have amniotic egg and hollow bones
T.rex & Birds
Bats & Giraffes
Spiders & Bats
Bats & Birds
According to the image, Bats are more closely related to ___________ than ______________
giraffes than birds
birds than giraffes
spiders than birds
spiders than t.rex
According to the diagram, which statement is NOT true?
All organisms represented evolved from a common ancestor with a backbone
Mammals are the only organisms represented with hair and warm blood
Living amphibians were the first represented with egg that can be laid in air
Living 'fish' were the first represented to branch off making living reptiles the most recent
What is the advantage to having an abundance of offspring?
probability of more offspring surviving and reproducing increases
probability of offspring survival decreases due to natural disasters
probability of offspring acquiring traits from parents that are better adapted the environment increase
probability of speciation derived from the offspring decrease
Having environmental fitness can be explained as
the ability to survive and reproduce
the ability to avoid predators and not reproduce
the ability to compete for resources and convince other organisms you are in charge
the ability to acquire needed traits from the environment from parent to offspring
Monotremes are organisms that are considered mammals but still lay eggs (such as the platypus & echidna). These organism having the same type of developmental process provides evidence of
a common ancestor
scientific falsification
validity to birds being closer related to humans than mammals
limited resources causing competition
