Evolution Test

When organisms are better adapted to their environment they will survive and reproduce more successfully than organisms less adapted. This process is called —

• selective breeding

• natural selection

• cloning

Both of these birds were originally the same species. Overtime, however, the two birds began to live in different environments and eat different types of food. What were these changes in beak and feather color caused by?

• extinctions

• mutations

• clones

Species that do NOT adapt to their environment are likely to..

• become extinct

• destroy the environment

• become evolved

Which would be considered an adaptation of an animal that lives in the water? 

• A thick coat. 
• Thick fur.  
• Webbed feet. 
• Green color skin.

Darwin observed 13 species of finches on the Galapagos Islands. What did Darwin conclude about the finches? 

• They evolved from a common ancestor.               
• They evolved from 13 different types of birds. 
• They all came from different continents. 
• They developed from other types of organisms. 

What did Darwin observe about finches in the Galapagos Islands?

• Their feathers were adapted to match their environment.

• Their beaks were adapted to match the foods they ate.

• They all looked the exact same.

The gradual change in a species over time is called

• mutation

• variation

• evolution

• migration

How does natural selection lead to evolution?

• Stronger offspring kill weaker members of the species.

• Best adapted members of a species pass on helpful traits.

• Environmental changes kill weaker members of the species.

Why did the population of peppered moths in England change from light to dark after the Industrial revolution? 

• Light moths were killed by soot.
• Dark moths were produced by industrial processes. 
• The birds that ate the dark moths were killed by the soot
• Light moths were more obvious against soot-stained trees

Most of what scientists know about extinct species is based on

• mutations

• the fossil record

• natural selection

• variations
