Evolution Part 1

A yellow morph and green morph of an insect lives in the rainforest canopy. You would expect:

• the green population to increase and the yellow to decrease

• both populations should stay the same

• both populations will increase

• the green population to decrease and the yellow to increaseThis is a wrong answer

How do you "win" at natural selection?

• survive

• go extinct

• survive & reproduce

Which organisms are most likely to survive?

• the best adapted
• the fastest
• the strongest
• the most domesticated (tamed)

Natural Selection is driven by a change in the environment and survival of the

• Earth

• Fastest

• Fittest

• Biggest

Darwin wrote that organisms with traits that are best suited to the environment will ________________

• increase in number

• become extinct

When individuals choose traits possessed by the opposite sex it is called…

• Mutation

• Gene Flow

• Genetic Drift

• Sexual Selection

Evolution responsible for a random change in a population is known as:

• Speciation

• Selection

• Genetic Drift

• Variation

Temporal isolation occurs when two different populations:

• develop different mating behavior

• become geographically separated

• reproduce at a different times

• interbreed

When two populations no longer interbreed, what is the result?

• genetic equilibrium

• stabilizing selection

• genetic drift

• reproductive isolation

When two species reproduce at a different times, the situation is called:

• temporal selection

• temporal drift

• temporal isolation

• temporal effect
