Multiple Choice

An explanation that is based on observation, experimentation, and reasoning

• Scientific Hypothesis

• Scientific Fact

• Scientific Theory

• Truth

Multiple Choice

____ is when members of a species that are best suited for their environment survive and reproduce at a higher rate than other members of the species

• natural selection

• artificial selection

• speciation

• adaptation

Multiple Choice

___ refers to the variety of life on Earth

• Natural Selection

• Biodiversity

• Biotic

• Variation

Multiple Choice

The individual who contributed more to our understanding of evolution than any other was?

• Charles Darwin

• Nikola Tesla

• Linus Pauling

• Albert Einstein

Multiple Choice

The differences among a species, like different bird beaks, are called

• theories

• variations

• adaptations

• genes

Multiple Choice

___ are mistakes in the DNA that cause variation within a species.

• mutations

• adaptations

• speciations

• isolations

Multiple Choice

Any inherited trait that gives an organism an advantage in its environment is called ___.

• a mutation

• an adaptation

• evolution

• natural selection

Multiple Choice

Evolution can be described as:

• A heritable change in the characteristics within a population from one generation to the next

• The process in which individuals with certain favorable inherited traits leave more offspring than individuals with other traits

Multiple Choice

Organisms with the most beneficial traits will survive.  This is commonly known as ___.

• theory of evolution

• variations

• survival of the fittest

• ecosystems

Multiple Choice

Most organisms have more offspring than will survive 

• True

• False

Multiple Choice

Why are advantageous traits more likely to be passed on to the offspring?

• Because parents with those traits can teach their offspring

• Because parents with those traits can surive and reproduce better

• Because parents with those traits care more about their offspring

Multiple Choice

Darwin conducted much of his research on

• the Samoan islands

• Manhattan island

• the Hawaiian islands

• the Galapagos islands

Multiple Choice

Natural selection could not occur without

• genetic variation in species

• environmental changes

• competition for unlimited resources

• gradual warming of the Earth

Multiple Choice

The struggle for existence against other members of an organisms species is

• competition

• adaptation

• genetic drift

• natural slection

Multiple Choice

According to Darwin, evolution occurs

• by chance

• during half life periods of 5,730 years

• because of natural selection

• rapidly

Multiple Choice

Organisms that are well suited to their environment

• reproduce at a greater rate than those less suited to the same environment.

• are always larger than organisms less suited to that environment.

• always live longer than organisms less suited to that environment.

• need less food than organisms less suited to that environment.

Multiple Choice

Refer to the illustration. The similarity of these structures suggest that the organisms

• have a common ancestor

• evolved slowly

• all grow at different rates

• live for a long time

Multiple Choice

Refer to the illustration. The bones that are green are know as

• vestigial structures

• homologous structures

• sequential structures

• fossil structures

Multiple Choice

Homologous structures in organisms suggests that the organisms

• have a common ancestor

• have a skeletal structure

• must have lived at different times

• are now extinct

Multiple Choice

The finches that Darwin studied differed in the shape of their beaks. According to Darwin, the finches probably

• all had a common ancestor

• had been created by design that way

• were descended from similar birds in Africa

• ate the same diet

Multiple Choice

Beak shape in finches is affected by

• the number of predators in the area

• the size of the finch

• the color of the finch

• the availability of food

Multiple Choice

Which of the following is a correct statement about the relationship between natural selection and evolution?

• Natural selection results from evolution.

• Natural selection included evolution as a part of it.

• Natural selection is one mechanism of evolution.

• Natural selection and evolution are the same thing.

Multiple Choice

Fitness is a result of

• adaptations

• homologies

• common descent

• variation

Multiple Choice

Which of the following is NOT evidence of evolution

• similarities in embryology

• homologies

• the fossil record

• acquired traits

Multiple Select

Which of the following are capable of "evolving"?

• Individuals

• Organisms

• Populations

• Species

Multiple Choice

What is the selecting agent in artificial selection?

• humans

• environment

• random chance

Multiple Choice

What is the selecting agent in natural selection?

• humans

• environment

• random chance

Multiple Choice

A mutation is a random change in the DNA. It will only persist (stick around in the population) if the trait is ______.

• beneficial

• harmful
