1. How did the Galapagos Islands come into existence?
Charles Darwin discovered them
2. Were plate tectonics involved?
Plate tectonics were not involved
3. How old are the Galapagos Islands?
They are 478 years old
4. What kinds of animals and plants are endemic to the islands?
There are tortoises and marine iguanas
5. How do species become endemic?
They become endemic because they are unique to a location
6. Where did the original colonists come from and how did they get to the Galapagos?
They came from Europe they got their by boat
7. What kind of special adaptations do the animals and plants have? How do adaptations evolve?
They have the adaptation o eat different foods they evolve through natural selection
8. How did these islands figure into Darwin’s ideas on evolution?
They figured in to his idea of evolution because each island had a different environment and each island had the same species but with different characteristics
1. What is DNA fingerprinting and how is it done?
It is identifying an individual with DNA it is done by collecting tissue
2. How can we measure evolution?
We can measure it by seeing the difference of one species in different environments
3. What is the difference between natural selection and evolution?
The difference is that in evolution they adapt to survive and in natural selection they die if they aren't strong to the environment
4. What is genetic drift and how could it be involved in evolution?
It is when it changes it's frequency of a gene it can be involved in evolution because if the frequency is high it will have a higher chance to evolve
5. What is resource partitioning and character displacement?
Resource partitioning is when two species share the resource they need, character displacement is when species disturbution overlaps
6. What is sexual selection?
Sexual selection is when one species reproduces more than another species and they survive
7. How might one test if beak size is due to genetic or environmental factors?
The shape of the beak is different depending on what they eat
8. If hybridization occurs during good times, what does this suggest about the degree of genetic differences between species?
It suggests that they can survive when they are in good times
9. What are reproductive isolating mechanisms and how do they evolve?
They are characteristics that prevent them from reproducing they evolve depending on the conditions of the environment
10. Must populations of finches be separated in order to evolve into different species?
They don't need to be different
11. What causes an El Niño?
This caused when water is piled up by the wind then the water becomes weak and not as much cold water piles up and it becomes warmer
1. Should Kate have chosen to work on a different species than the tortoises that are being threatened? Her thesis work might be destroyed by the politics of the islands.
she should stay with the tortoises because they are almost extinct
2. Should Kate get involved in the politics of saving the islands, the way Dian Fossey did in trying to save the Mountain Gorilla?
She should get into politics to save the island because there are alot of animals that cant protect themselves alone
3. Should fishing, tourism, or inhabitants be allowed in the islands?
It shouldn't be allowed because there are alot f endangered species and some people don't know which species are endangered
4. How should the Ecuadorian government deal with the conflicts over the islands?
They should allow a certain amount of fishing so they don't go extinct
5. Extinction is a natural phenomenon. Why should we worry about whether a few species on some remote islands in the Pacific survive or not?
We should worry because they are unique and it can affect the environment
