Evolution by Natural Selection Quiz

What are the two variations of color in the peppered moth species?

• Purple with pink swirls and gray with silver lines

• White with dark circles and dark with light speckles

• Red with yellow stripes and blue with green spots

• Black with white stripes and brown with orange dots

In an environment with light-colored trees like birch trees, which color variation of moths had an advantage for survival?

• White with dark circles

• Purple with pink swirls

• Black with white stripes

• Red with yellow stripes

What is the advantage of the light-colored moths in the environment with light-colored trees?

• They can hide from predators

• They can fly faster

• They can camouflage in the dark

• They can eat more food

What caused the frequency of the dark colored moths to increase after the Industrial Revolution?

• The moths adapted to the pollution

• The predators preferred dark colored moths

• The trees naturally changed color to dark

• The pollution from coal factories covered the trees with dark soot

What led to the decrease in frequency of dark colored moths after the reduction of emissions by factories?

• The light moths became more aggressive

• The dark moths lost their ability to blend into the environment

• The predators started eating more dark colored moths

• The skies became clear and the trees returned to their natural light color

What is the definition of natural selection?

• The process by which organisms adapt to their environment by their choice

• The process by which organisms better adapted to their environment tend to survive and produce more offspring
• The process by which organisms randomly survive

• The process by which organisms worse adapted to their environment tend to survive and produce more offspring

An organism becomes more fit for its environment and can survive better.

This is called

• a mutation

• an adaptation

• a DNA strand

• predation

If, way back in the past, multiple species evolved from the same organism, that organism would be known as

• a descendant

• a parent

• a common gene

• a common ancestor
