A genetic mutation causes a newt to have faster reflexes. After many generations, most of the newt population has the reflex mutation.
Which of the following most likely caused this change?
Newts with the mutation are better able to survive and reproduce than newts without the mutation.
Other newts learned to copy the strategies of the mutated newt.
The newt passed on its mutated gene to other adult newts
The mutation was contagious.
Cheetahs have come close to extinction due to hunting, drought, and disease. This has caused a decrease in the genetic variation in their populations.
Which of the following is a result of the limited genetic variation?
The cheetah populations are less likely to be able to adapt to environmental changes.
Cheetahs in current populations are more resistant to new diseases.
Cheetahs have greater mate choice.
The survival rate of young cheetahs is increased.
Which of the following is true regarding Darwin's theory of evolution?
Characteristics acquired during an individual’s life are always passed on to future generations.
Pure chance determines which species evolve.
Species change over long periods of time, giving rise to new species.
Darwinʼs views are no longer accepted by the scientific community.
Which of the following are true about natural selection?
It can cause an individual to become better adapted over its lifetime.
It acts on existing heritable variation.
It means that certain species have a programmed plan for evolution.
It always results in bigger, stronger individuals.
Which of the following is an example of genetic variation?
One child eats meat and the other is a vegetarian.
One child has a scar and the other does not.
One child is older than another.
One child has blue eyes and the other has brown eyes.
