What is the advantage of having different shaped beaks?

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.

Do organisms "decide" to evolve and change?

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

What is most likely to happen to moth populations in the picture shown?

• Light moths--hunted easily, dark moths--population increase

• Dark moths--hunted easily, dark moths--population increase

• Light moths--hunted easily, light moths--population increase

• Lights moths will change their color to match dark moths.

Definition: Natural Selection

• inherited characteristic that increases chances of survival

• a growing population causes a scarcity of resources

• organisms with traits well suited to their environment survive and reproduce at a greater rate

• differences in the DNA sequence
