• The probability that an organism will be able to reproduce in its environment
Answer 2 – 10

Question 2 - 20
• A change in behavior or body which help an organism survive in its environment
Answer 2 – 20

Question 2 - 30
• Changes in genes which are passed down to future generations
Answer 2 – 30
• What are mutations?
Question 2 - 40
• Traits which are not genetic, but are developed during an organism’s lifetime
Answer 2 – 40
• What are acquired traits?
Question 2 - 50
• Difference from the normal body or behavior of a species
Answer 2 – 50
• What is variation?
Question 3 - 10
• The theory that the genetic code of a species can change from generation to generation over time
Answer 3 – 10
• What is evolution?
Question 3 - 20
• The theory that speciation occurs in very small steps over a long period of time
Answer 3 – 20
• What is gradualism?
Question 3 - 30
• The theory that speciation occurs in occasional periods of extreme change, between long periods of no change
Answer 3 – 30
• What is punctuated equilibrium?
Question 3 - 40
• The theory that organisms which are better adapted to their environments are more likely to survive, reproduce, and pass their traits on to future generations
Answer 3 – 40
• What is natural selection?
Question 3 - 50
• The theory that a meteor covered the earth with dust that blocked out the sun, resulting in the death of all dinosaurs, would explain this.
Answer 3 – 50

Answer 4 – 20
• What are Darwin’s finches?
Question 4 - 30
• The oldest fossils of this species look more like land mammals than they look like their modern day equivalent.
Answer 4 – 30
• What are whales?
Question 4 - 40
• Sometimes fossils show that this older version of any organism looks very different from its current version.
Answer 4 – 40
• What is an ancestor?
Question 4 - 50
• Peppered moths are more likely to survive if they look like this.
Answer 4 – 50
• The bark of the tree they sleep on.
Question 5 - 10
• A cast fossil can only form if this exists first.
Answer 5 – 10
• Mold fossil
Question 5 - 20
• Hummingbird beaks getting longer as the flowers they pollinate become deeper is an example of this type of change.
Answer 5 – 20
• Coevolution
Question 5 - 30
• Flippers in a dolphin and wings in a bird are an example of these structures.
Answer 5 – 30
• What are analogous structures?
Question 5 - 40
• A single species may separate into 2 types of organisms which can no longer be considered variations within the same species
Answer 5 – 40
• What is speciation?
Question 5 - 50
• One species becomes geographically separated into 2 groups, and eventually those 2 groups become separate species.
