Selective breeding
Natural Selection
Cloning
Evolution of all species
Which scientist visited the Galapagos Islands and came up with the theory of natural selection?
Theodor Schwann
Gregor Mendel
Charles Darwin

Scientists have collected millions of fossils of different organisms, and have developed a timeline of life on Earth. What do we call this?
Mutation
Natural Selection
The theory of evolution
Fossil Record
Sometimes bones in the front limbs of animals are very similar in structure. What do we call similar bone structures that indicate a link to 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 most likely caused the finches on the Galapagos Islands to have beaks that were different from the finches on the mainland?
There were different types of predators on the island.
There were different types of food available on the island.
The finches had no water to drink.
The finches on the mainland could not fly high enough.
What do we call a change in a species over time?
Adaptation
Evolution
Extinction
Environmental influences
Evolution is best defined as:
the process which organisms die.
the process which organisms change over time.
the process which organisms that are extinct become revived.
the process which non-living things fossilize.
The solidified remain or imprint of a once living thing are called:
Fossils
Homologous Structures
Vestigial Structures
DNA
What caused the Horse and Whale to evolve?
