The opossum and kangaroo both incubate their young in a pouch. This provides evidence that they---

• are descended from a common ancestor
• Have very similar skeletal structures
• belong to the same species
• must range great distances to eat

The white feathers of a snowy owl allow it to blend in with its environment during the winter months (snow). This is an example of ________________

• Species
• Environmental Change
• Adaptation
• Variation

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

A prey population consists of individuals with a variety of running speeds.
The adaptation that allows some of these animals to run fast would be an example of natural selection if it helps them —

• survive and undergo mutations in their DNA
• produce offspring that run at average speeds
• reproduce and increase the frequency of their genes in the population
• lower the mortality rates of the population
