A population of squirrels that contains a wide variety of phenotypes has a:

• Large amount of genetic variation

• High allele frequency

• Poor chance of surviving habitat change

• Decreased chance of frequent gene flow

When a species is separated by water, what type of speciation can occur?

• Geographic Isolation
• Reproductive Isolation
• Genetic Drift
• Coevolution

Gradualism or Punctuated Equilibrium?
Fossils show a sequence of difference between earliest camels and camels of today

• Gradualism
• Punctuated Equilibrium

Gradualism or Punctuated Equilibrium?
Species of bacteria showing resistance to antibiotics

• Gradualism
• Punctuated Equilibrium

Gradualism or Punctuated Equilibrium?
Species of insects showing resistance to pesticides

• Gradualism
• Punctuated Equilibrium

The graph displays periods of abrupt changes after long periods of little change which is:

• Adaptive radiation
• Gradualism
• Punctuated equilibrium
• Extinction

A population of chimpanzees was separated when the forest that they lived in had a section cut down and a town was built. After a long period of time, the chimpanzees came back into contact but were incapable of breeding. Which of the following best describes the process that occurred?

• adaptation
• speciation
• convergent selection
• stabilizing selection
