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.

The image illustrates what evidence of evolution? (DOK 1)

• Embryological similarities

• Variation among species

• Vestigial Structures

• Homologous Structures

Any variation that can help an organism survive in its environment is called a(n): (DOK 1)

• Characteristics

• Adaptations

• Competition

• Vestigial structures

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

In terms of biology, what is fitness?

• the ability of an organism to adapt to various habitats

• the number of individuals an organism mates with

• the ability to survive and produce offspring

• the strength of an organism

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
