Evolution

Multiple Choice

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

• vestigial structures
• homologous structures
• adaptive radiation
• fossil

Multiple Choice

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

• natural selection
• embryology
• speciation
• evolution

Multiple Choice

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

Multiple Choice

The hind leg bones in a whale are examples of

• homologous structures
• analogous structures
• fossils
• vestigal structures

Multiple Choice

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

Multiple Choice

How do fossils support evolution?

• The fossil record provides evidence that organisms have changed over time.

• Individual species disappear and reappear in the fossil record over time.

• The fossil record provides evidence that all organisms developed at the same time.

• Organisms in the fossil record are identical to living organisms.
