Evolution Theory

1. Which of the following is REQUIRED for the process of natural selection to occur? (DOK 1)

• Members of the same species must compete with one another.

• Members of different species must compete with one another.

• There must be a sudden environmental change.

• Traits must be inherited from one generation to the next.

Which of the following best defines the Theory of Natural Selection? (DOK 1)

• Organisms that are the biggest and the strongest always survive

• The smallest organisms in a population are always eliminated by the biggest organisms

• The organisms that occupy the largest area always survive and reproduce

• The organisms that are best adapted always survive and reproduce

According to the theory of natural selection, what would happen to a species of lizards when a new predator is introduced into the environment where the lizards live? (DOK 2)

• The lizards that have the traits needed to avoid the new predator would be more likely to survive and reproduce

• All of the lizards would try to develop new physical traits to avoid the new predator.

• Some of the lizards would try to develop new physical traits to avoid the new predator, and the other lizards would die.

• Because all lizards of the same species have the same physical traits they would either all survive or all die.

Which of the following statements is not one of the ideas Lamarck had regarding evolution? (DOK 1)

• Lamarck believed organisms could acquire adaptations out of need.

• Lamarck concluded if an organism did not use a trait it would be lost over time due to disuse.

• Lamarck thought traits acquired in an organism’s lifetime would be passed down to offspring,

• Lamarck understood that natural variations occurred in populations and nature selected for or against these adaptations

Variation in a population is increased by which of the following? (DOK 1)

• Inbreeding

• Emigration

• Mutations

• Genetic drift

Of all the evidence for evolution, what is considered to be the strongest?

• DNA/Genetic Evidence

• Fossil Evidence

• Embryological Evidence

• Direct Observation Evidence

Based on the biochemical evidence above which two species are probably more closely related? (DOK 2)

Species I = ATC CAT GCA

Species II = CGT TAA GCC

Species III = CAT TAA CGG

• Species I and II are more closely related.

• Species II and III are most closely related.

• Species I and III are more closely related.

• Not enough information to tell
