BIO: Evolution

What is the term for a feature that allows an organism to survive in its environment?

• adaptation
• variation
• homologous structure
• vestigial structure

• analogous structures
• homologous structures
• vestigial structures
• none of the above

What is the process of which humans breed organisms for certain traits?

• artificial selection
• descent without modification
• inheritance of acquired characteristics
• natural selection

Individuals that are well adapted to their environment will survive and produce

• better traits
• stronger genes
• more offspring
• fewer mutations

All the individuals of a species that live in a particular area are called a 

• group
• population
• variation
• fossil

The remnant of an organ that had a function in an early ancestor is known as a(n)

• vestigial structure
• analogous structure
• homologous structure
• fossil structure

What is the study of the distribution of organisms around the world?

• geology
• biogeography
• paleontology
• geography

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 are correct 

The fossil record provides evidence that 

• Fossils cannot be dated.
• All species were formed during Earth’s formation and have changed little since then.
• The fossilized species have no connection to today’s species.
• Older species gave rise to more-recent species.

The process in which organisms with traits well suited to an environment are more likely to survive and to produce offspring is

• Natural Selection
• Origin of Species
• Genetic Principles
• Trait Mechanism
