evolution

When an organism completely dies out, it is called.....

• adaptation

• extinction

• fossilization

• mutation

Mistakes or changes that occur in the DNA sequence are called....

• adatations
• Darwinism
• mutations
• natural selection

What do we call similar physical structures that indicate a link to a common ancestor?

• absolute dating
• adaptations
• gradualism
• homologous structures

The preserved remains or physical evidence of an organism that lived in the past are called...

• evolutionary features
• fossils
• mutations
• variations

Which would NOT be considered a fossil?

• bones buried deep in the earth
• footprints harened in  mud or rocks
• imprints left in rocks
• stories passed down from generation to generation

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

• adaptation
• variation
• homologous structure
• vestigial structure

This illustration represents...

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

What is the process called when humans breed organisms for certain traits?

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

Vertebrate embryos pass through similar stages of development is evidence for

• use and disuse
• homologous structures
• common ancestry
• acquired characteristics

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

• more mutations

• less genes

• more offspring
• fewer mutations
