Which would be the best description of Evolution?

• Gradual changes to a population over time

• Rapid changes where one organisms becomes another

• Mutations cause species to rapidly adapt to their environment

• A method no longer used for species to adapt to their environment

Which of the following are components of Natural Selection?

• Inheritance of traits

• Variation of traits

• Developmental homologies

• Differential Survival & Reproduction

Which would be the best match for the term "alleles"?

• Variation in genes

• Variation in traits

• Variation in coloration

• Variation in phenotype

Which of the following are ways in which evolutionary change can occur?

• Natural Selection

• Sexual Selection

• Mutation

• Genetic Drift

• Gene Flow

What is a type of evidence that shows that similar organisms share a common ancestor in the past

• Homologies

• Sexual Selection

• Natural Selection

• Natural Disasters

For what reasons would the picture not be a literal example of how common ancestry works?

• It fails to account for how female choice can lead to certain phenotypes being more pronounced

• Organisms with common ancestry have branching lines of descent - not one into another

• Each "step" would actually be over the course of hundreds of thousands of years

• It does not describe how mutations can cause humans to develop their intelligence.

Over time, the red fox and arctic fox were separated as their habitats began further and further apart. This would be an example of...?

• Sexual Selection

• Genetic Drift

• Speciation

• Mutation

Organisms that are better __________ to their environment are more likely to survive and produce offspring

When organisms reproduce, they are passing their __________ onto their children - meaning they are likely to share the same traits.

Natural selection needs all of the following but which to occur?

• Organisms being able to pass their genes into their offspring

• A variety of traits in their gene pool

• That females have certain preferences in male traits

• That their is competition for resources and survival
