Evolution Review

Evolution is best defined as:

• the process which organisms die.

• the process which organisms change over time.

• the process which organisms that are extinct become revived.

• the process which non-living things fossilize.

What type of evidence is represented in the picture above:

• Fossils

• Vestigial Structures

• DNA

• Homologous Structures

What type of evidence is shown in the image above?

• Fossils

• Vestigial structures

• Homologous Structures

• DNA

What type of evidence is shown in this picture?

• Fossils

• Homologous Structures

• Vestigial Structures

• DNA

Adaptations are:

• physical or behavioral tendencies.

• physical or behavioral characteristics that help an organisms survive and reproduce.

• physical or behavioral characteristics that do not help the organism in any way.

• genetic mutations that have gone wrong.

The similarities of the bones in the diagram provide evidence that---

• The organisms shown lived in the same natural envionrment
• The organisms shown may have developed from a common ancestor
• The organisms shown have the same genetic diseases
• All vertebrate species have identical forelimbs

According to this data, the unknown bacterial species is most closely related to: 

• Species I
• Species II
• Species III
• Species IV

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

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice
• The hawks eat more dark mice than light mice because the dark mice taste better
• The hawks eat more light mice than dark mice because they can see the light mice more easily
• The hawks eat more dark mice than light mice because they can see the dark mice more easily

A species is defined as:

• a group of organisms that are extremely different.

• a group of organisms that have similar characteristics and always live in the same place.

• a group of organisms with similar characteristics and can reproduce to make fertile offspring.

• any two organisms to make a hybrid.
