1. How did the Galapagos Islands come into existence? The Galapagos islands were a chain of Islands, and now today some of them are submerged under water.
They were formed from a hot spot at the bottom of the ocean which occasionally bubbled up magma.
2. Were plate tectonics involved?
No
3. How old are the Galapagos Islands?
The Galapagos Islands are around five million years old.
4. What kinds of animals and plants are endemic to the islands?
Variety of tortoise, the marine iguana and prickly-pear cactus, white-tipped sharks, Galapagos penguin and masked boobies.
5. How do species become endemic?
A species becomes endemic when it has evolved in such a manner that it can only survive in a specific region or place. This species however is highly adapted to it's specific environment.
6. Where did the original colonists come from and how did they get to the Galapagos?
Europe
7. What kind of special adaptations do the animals and plants have? How do adaptations evolve?
The kind of special adaptations do the animals and plants have is the Finch. Adaptations evolve is natural selection.
8. How did these islands fi gure into Darwin’s ideas on evolution?
Darwin thought each island had different environmental conditions, leading to different adaptations on each island.
1. What is DNA fingerprinting and how is it done?
A scientific procedure used to determine identity or parentage using DNA. It taking samples of body tissues or fluids of the individual.
2. How can we measure evolution?How the seeds of plants vary in their hardness.
3. What is the difference between natural selection and evolution?
Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift.Evolution is the biological model for the history of life on Earth.
4. What is genetic drift and how could it be involved in evolution?
Genetic drift is the change in the frequency of a gene variant (allele) in a population due to random sampling because with the frequency being high, the organism will have a higher chance to evolve with that gene.
5. What is resource partitioning and character displacement?
The resource partitioning is the concept of resource partitioning, as originally developed, relates to evolutionary change in species in response to selection pressures generated by interspecific competition.Character displacement is when similar species habits overlap, and they are in direct competition for food and other vital resources.
6. What is sexual selection?
Sexual selection is the natural selection that results from the preference by one sex for features in individuals of the other sex such as form, colour or behaviour.
7. How might one test if beak size is due to genetic or environmental factors?
Change the factor in that area, and measure the beaks over time to see if it is environmental.
8. If hybridization occurs during good times, what does this suggest about the degree of genetic differences between species?
The suggest about the degree of genetic differences between species is shows that these genetic differences are more beneficial in good times.
9. What are reproductive isolating mechanisms and how do they evolve? The reproductive characteristics which prevent species from fusing.It evolves through the conditions of the environment.
10. Must populations of fi nches be separated in order to evolve into diff erent species?
mo
11. What causes an El Niño?
El Ni'o is caused by, simply, the wind. El Ni'o happens when the wind blows with strength from the east to the west along the pacific ocean.
1. Should Kate have chosen to work on a diff erent species than the tortoises that are being threatened?
Her thesis work might be destroyed by the politics of the islands.
Kate should stay on the species of the tortoises
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 involved in politics of saving the islands.
3. Should fi shing, tourism, or inhabitants be allowed in the islands?
Fishing, tourism and inhabitants shouldn't be allowed
4. How should the Ecuadorian government deal with the confl icts over the islands?
Promise the people a fishing season and limit amount of fish caught
5. Extinction is a natural phenomenon. Why should we worry about whether a few species on some
remote islands in the Pacifi c survive or not?
The extinction of these species the island would be just like any other island in the world.
They were formed from a hot spot at the bottom of the ocean which occasionally bubbled up magma.
