• natural selection
• embryology
• speciation

Multiple Choice

What type of evidence are shown in the picture above?

• Fossils

• Embryology

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.

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.

Multiple Choice

Relative dating of rock layers tells us that the deeper we dig, 

• the younger the rocks get.
• the simpler the rocks get.
• the harder the rocks get.
• the older the rocks get.

Multiple Choice

• 1
• 2
• 3
• 4

Multiple Choice

Which layer is the oldest

• B
• A

Multiple Choice

The diagram shows a portion of the fossil record in sedimentary rock. Different rock layers and fossils are clearly visible. Which of these statements is true of the fossils and rock layers shown in the diagram?

• Layer B contains the second-oldest fossils.

• Layer A contains the most recently formed fossils

• The fossils in layer B are older than those in layer D.

• The fossils in layer D are the most recently formed

Multiple Choice

Which of these statements is true about DNA and evolution?

• Two species that have the same DNA provide evidence that evolution has taken place.

• Two species with very similar DNA likely evolved from a common ancestor.

• Each living species has DNA made from different ingredients, showing that organisms have evolved.

• DNA from related species is identical, providing evidence that all organisms have evolved in the same way.
