Evidence of Evolution

Structures with the same parts have different functions; suggests that organisms share a common ancestry

• vestigial structures
• homologous structures
• adaptive radiation
• fossil

Study of embryos of various organisms to show a common ancestor because of similarities in development

• natural selection
• embryology
• speciation
• evolution

Two organisms that are closely related would have

• very similar DNA sequence
• exactly the same DNA sequences
• no proteins in common
• completely different DNA sequence

What does Darwin's theory of evolution suggest?

• species change over time
• extinct species are not related to living species
• different species can interbreed
• animals that look alike are most closely related

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures

Which is not evidence for evolution?

• many animals have homologous structures due to common ancestry
• Many animals have vestigial structures from an ancestor
• We can observe changes in life forms by observing the fossil record
• All of these are evidence for evolution

When all of the organisms of a species have died it is called

• evolution
• extinction
• adaptation
• natural selection

Predict which moth would increase in population

• light 
• dark

The diagram illustrates an embryonic stage of two organisms.

Which of the following can be determined by observing the embryos shown in the diagram

• The organisms share a common ancestry.
• The organisms belong to the same genus.
• The organisms are native to the same geographic areas.
• The organisms will grow into anatomically similar adults.

Which species’ DNA is most similar to the DNA of the toothed whale? 

• Hippopotamus 
• Baleen Whale
• Grazing Mammals
• Camels
