Darwin’s Voyage Guided Reading--KEY
1. Who was Charles Darwin and what did he do on the Beagle’s voyage?
NATURALIST-STUDIES THE NATURAL WORLD
2. Darwin’s observations of plants and animals led him to what?
THE THEORY OF EVOLUTION BY NATURAL SELECTION
3. What is a species?
GROUP OF SIMILAR ORGANISMS THAT MATE AND PRODUCE FERTILE OFFSPRING
4. List 3 animals Darwin saw on the Galapagos Islands.
BLUE FOOTED BOOBY, CRABS, LIZARDS, SEALS, HAWKS, TORTOISE
5. How did he propose that the plants and animals got to the islands from the mainland?
BLOWN OUT TO THE ISLAND, DRIFTED WITH DEBRIS OR ON LOGS AFTER STORMS
6. On page 142- How are the two species of iguanas similar and different?
LAND-GREEN, SMALL CLAWS, EAT LEAVES OF TREES
ISLAND-GRAY, BROWN, LARGE CLAWS, LIVE ON ROCKS, AND EAT SEAWEED
7. What is an adaptation?
TRAIT THAT HELPS ORGANISMS SURVIVE AND REPRODUCE
8. Explain how the shape of a finch’s beak is an example of an adaptation.
STRONG AND WIDE FOR BIG SEEDS, SMALL AND NARROW FOR INSECTS, ETC.
9. What is evolution?
GRADUAL CHANGE IN SPECIES OVER TIME
10. What observations led Darwin to propose his theory of evolution?
HE SAW CHANGES IN SPECIES THAT MADE THEM BETTER ADAPTED TO THEIR
ENVIRONMENT
11. What is a scientific theory?
WELL TESTED CONCEPT THAT EXPLAINS OBSERVATIONS
12. What is natural selection?
PROCESS BY WHICH INDIVIDUALS ARE BETTER ADAPTED AND MORE LIKELY TO SURVIVE
AND REPRODUCE
13. Explain overproduction.
SPECIES PRODUCE MORE OFFSPRING THAN WILL SURVIVE TO REPRODUCE
14. When members of a species compete, what do they compete for?
RESOURCES (SHELTER, FOOD, WATER, ETC) AND MATES…SURVIVAL
15. How do helpful variations accumulate in a species over time?
THE GOOD VARIATIONS ARE KEPT BY SPECIES AND THE BAD ONES GO AWAY.
16. What can natural selection lead to? And how does this happen?
EVOLUTION-HELPFUL VARIATIONS GRADUALLY ACCUMULATE AND BAD ONES DISAPPEAR
17. What example of natural selection does the book give and how does the new “trait” help?
NEW FAST SWIMMING PREDATOR MOVES IN- ALL TURTLES EVENTRUALLY BECOME FAST
SWIMMERS TO GET AWAY FROM THE FAST PREDATOR….THE ONLY MEANS OF SURVIVAL.
18. What would happen without variations?
ALL MEMBERS WOULD HAVE THE SAME TRAITS AND WOULD BE EXACTLY THE SAME.
19. What is isolation or complete separation?
AN INDIVIDUAL OR GROUP OF INDIVIDUALS WITHIN A SPECIES IS KEPT FROM
REJOINING THE MAIN GROUP OF THEIR RELATIVES.
20. Give some examples of how a group can be separated.
CATASTROPHIC EVENT, WATER, DRIFTING TO AN ISLAND FROM MAINLAND, MOUNTAINS,
21. Explain how geographic isolation can result in the formation of new species.
A NEW SPECIES CAN FORM WHEN A GROUP IS SEPARATED EVOLVES BECAUSE OF
PARTICULAR ADAPTATIONS NEED FOR THE NEW ENVIRONMENT
22. How is geographic isolation and Pangaea related?
PANGAEA SPLIT UP (CONTINTENTAL DRIFT) AND AS IT SPLIT SAME SPECIES BECAME
ISOLATED FROM ONE ANOTHER BECAUSE OF THE OCEAN AND THE SPECIES CHANGED
OVER TIME TO MEET THEIR NEEDS TO SURVIVE IN THE NEW HABITAT/ENVIRONMENT
