Evolution and Natural Selection Review

Artificial Selection can be defined as...

• The selective breeding of organisms by humans for specific, desirable characteristics.

• The process where individuals with certain characteristics that make them better adapted to their environment survive

• The change in characteristics of a population from one generation to the next.

• The differences in heredity among a population

Which answer choice provides an example of artificial selection?

• A farmer collects seeds of plants that grow larger fruit, then plants more of this type of seed.

• A dog breeder controls the type of dogs that mate to produce dogs with thicker fur.

• A rancher breeds cattle with long horns to produce more longhorn calves.

• Each answer choice is an example of artificial selection.

An adaptation can be defined as...

• A random change that occurs in the genetic makeup of an organism.

• The environment in which an organism lives.

• A characteristic that allows a population to survive while another population does not survive.

• The change in characteristics of a population from one generation to the next.

Which answer choice is an example of an adaptation?

• A group of deer have thick fur that keeps them warm in the winter time.

• A bird has a beak that allows it to eat a specific type of insect.

• A group of peppered moths has a darker skin color that allows them to blend in with the dark smoke in the sky

• Each answer choice is an example of adaptation.

Which answer choice provides a correct definition for natural selection?

• A type of selective breeding where humans control how organisms mate.

• The process of two species evolving in response to a long-term interaction.

• The process where individuals or populations that have characteristics that make them better adapted to their environment survive.

• A change in characteristics among a population from one generation to the next.

Evolution of Resistance (a.k.a. Resistance) is when...

• Two species evolve in response to long-term interactions with each other.

• A species develops the ability to tolerate a chemical or disease-causing agent

• Humans determine how plants and animals mate to produce offspring with specific characteristics.

• A species resists the process of evolution

Which answer choice provides a correct definition for co-evolution?

• The process of becoming adapted to the environment

• The process in which individuals that are better adapted to their surrounding are able to survive

• The process of two species evolving in response to long term interactions with one another

• All of the answer choices provide a correct definition for co-evolution
