Evolution A Level Quiz

What is natural selection?

• The process where organisms better adapted to their environment tend to survive and produce more offspring.

• The process of plants adapting to their environment

• The process of artificially breeding animals

• The process of animals choosing their own mates

What is genetic drift?

• Mutation of a gene due to environmental factors

• Evolution caused by intentional breeding

• Change in the frequency of a gene variant in a population due to natural selection

• Change in the frequency of a gene variant in a population due to random sampling

What is speciation?

• The process by which new species arise

• The process of creating hybrids between different species

• The process of combining two different species into one

• The process of extinction of species

What is adaptation?

• The process of change by which an organism becomes worse suited to its environment

• The process of change by which an organism or species becomes better suited to its environment.

• The process of change by which an organism becomes suited to a different environment

• The process of change by which an organism stays the same in its environment

What does the fossil record provide evidence for?

• The discovery of new species

• The history of life on Earth, including the evolution and extinction of species.

• The formation of the Earth's crust

• The study of weather patterns

Which of the following is an example of natural selection?

• The adaptation of peppered moths to their environment due to industrial pollution causing a change in their coloration.

• The domestication of dogs by humans

• The invention of the light bulb

• The construction of skyscrapers

What is the main driver of genetic drift?

• Natural selection

• Mutation

• Environmental factors

• Random chance events

What is the result of speciation?

• Extinction of species

• No change in species

• Hybridization of species

• New species

How do organisms typically adapt to their environment?

• Through random mutations and luck

• By avoiding their environment completely

• By staying the same and not changing at all

• Natural selection, genetic variation, and behavioral changes

What can the fossil record tell us about the history of life on Earth?

• The fossil record only contains information about extinct species and not the history of life on Earth

• The fossil record is not a reliable source of information about the history of life on Earth

• The fossil record can tell us about the future of life on Earth

• The fossil record can provide evidence of the types of organisms that lived in the past, their relationships to each other, and how they have changed over time.
