QUIZ 4.2 Darwin's Theory of Evolution by Natural Selection

A population of giant tortoises found in Galapagos Archipelago have longer necks than those that lived on other islands with dry lowlands. This is an example of:

• Selection

• Time

• Inheritance

• Variation

Which of the following shows how natural selection CAN'T change a population?

• Living organisms adapt and change

• Outgrow its food supply

• Population increases

• Produce new species

How does Natural Selection affect an ecosystem?

• Changes weather

• Changes animal’s instincts

• Creates new species

• Forms new land masses

What animal did Charles Darwin observe that made him realize that species could change over time?

• Finches

• Newts

• Spiders

• Turtles

Which is not a principle of natural selection?

• Adaptation

• Heritability

• Overproduction

• Variation  

Which statement is TRUE about artificial and natural selection?

• Artificial selection affects the population but not natural selection.

• Artificial selection happens faster than natural selection.

• Artificial selection is manipulated while natural selection occurs naturally.

• Artificial selection occurs naturally while natural selection is manipulated.

How are desirable traits passed down and enhanced in plants and animals?

• Artificial selection

• Devolution 

• Hybrid

• Natural selection

What evidence did Darwin find to prove species change over time?

• Darwin noticed animals on the Galapagos islands differed from the same species in South America.

• Darwin went to North America and observed the evolution of plants.

• Darwin found out dinosaurs were ancestors to a lot of animals and started to believe that animals had to change overtime due to their environment.

• He found no evidence.

How are traits naturally passed down from one organism to another?

• Artificial selection

• Devolution  

• Hybrid

• Natural selection

Organisms obtain traits that offer an advantage and will most likely be passed on to offspring through the process of natural selection.

• True

• False
