Evidence of Evolution & Natural Selection

Two organisms that are closely related would have

• very similar DNA sequence

• exactly the same DNA sequences

• completely different DNA sequence

Scientists compare organisms' DNA to support the theory that all species share a common _________________

• species

• ancestor

• population

• environment

The diagram shows the embryos of a bird and a reptile.

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

• The organisms share a common ancestor.

• The organisms belong to the same genus.

• The organisms live in the same geographic areas.

• The organisms will grow into anatomically similar adults.

The diagram shows fossils in different rock layers. Which of these statements about the age of these fossils is most likely correct?

• Fossil A and C are the same age
  
• Fossil B is older than fossil C
• Fossils A is older than fossil B
• Fossil D is older than fossil C

The picture shows the members of the Camelidae family. The physical features and the geographical origin of these animals provide evidence that they

• live in the same type of environment.

• have slowly evolved to become herbivores.

• likely have a common ancestor.

• exchanged DNA in the past.

What is the fossil record?

• The remains or evidence of once-living organisms

• The change over time in populations of related organisms

• All the fossils ever discovered on Earth

• Occurs when the last individual organism of a species dies

According to the theory of natural selection, some individuals more likely than others to survive and reproduce because they:

• Pass on to their offspring their newly acquired traits.

• Are better adapted to their environment than others and will pass on those adaptations to future offspring.

• Do not pass on newly acquired traits.

• Produce fewer offspring than others in the same environment.

When every organism of a species has died.

• Evolution
• Natural Selection
• Extinction
• Artificial Selection
