Natural Selection, Adaptation, and Evolution

This scientist developed the theory of evolution as he studied the finches.

• Charles Darwin
• Isaac Newton
• Albert Einstein
• Marie Curie

Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring? 

• Evolution 
• Variation 
• Adaptation
• Natural Selection 

What is a change in an organism that allows for it to survive in its environment?

• homologous
• vestigial
• variation
• adaptation

The differences among a species, like different colors or stripes, are called

• genes.

• variations.

• traits.

• theories.

When all of the organisms of a species have died it is called

• evolution
• extinction
• adaptation
• natural selection

What is natural selection?

• The process by which individuals with beneficial traits produce more offspring

• The ability of an organism to change its color

• A random process that occurs without any environmental influence

• The process by which individuals learn to adapt to their environment

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.

• Because they come from dominant alleles.

• Because they come from recessive alleles.

• Because the organism knew it needed that trait, survives, and passes it on.

What is the best definition of evolution?

• The process by which individuals change their traits during their lifetime

• The process by which species change over long periods of time

• The sudden appearance of new species

• The change of one individual into another species

Which of the following is an example of a physical trait?

• A bird’s migration pattern

• A rabbit’s thick fur in the winter

• A dog learning to fetch

• A bear hibernating during cold months

Which of the following is an example of a behavioral trait?

• The long neck of a giraffe

• The sharp claws of a hawk

• A turtle hiding in its shell when frightened

• The spots on a leopard’s coat
