• Artifical Selection

What are the most studied animals in the galapagos?

• Finches
• Tortoises
• Turtles
• Lizards

What is the advantage of having different shaped beaks?

• To look different from other species.
• To be able to eat the food readily available in the environment.
• To protect itself against predators.
• To protect itself against prey.

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 trait is an acquired phenotype.

Mutations are a change in what?

• DNA
• tRNA
• genotype
• phenotype

Do organisms "decide" to evolve and change?

• Yes, they know they need to change to survive 
• No, they change because of natural selection

Almost all adaptations started off as?

• selective breeding
• physiological
• structural
• mutation

What word describes a trait that helps an organism survive in its environment?
