Where did Darwin do most of the work which lead to his hypothesis of evolution?
|
he did most of his work on the HMS Beagle
|
|
Did Darwin ever recant his scientific beliefs?
|
No he did not
|
|
What was the main idea that Thomas Malthus's work gave to Darwin?
|
Malthus believed in a constant struggle for survival
|
|
What was the main idea that Sir Charles Lyell's work gave to Darwin?
|
Lyell came up with the idea that the present is the key to the past. He thought that the entire geological column could be explained by referring to the same process that we see happening today

|
Darwin dispelled the idea of the immutability of the species.
|
|
Suppose a herd of horses were living in an area where food near the ground was scarce but there was plenty of food in the trees. If, after several generations, the horses gave rise to giraffes that could easily reach the food in the trees, would this be an example of microevolution or macroevolution?
|
macroevolution
|
|
consisder a fish population that is trying to survive under conditions of extremley cold water. If, over several generations, the fish develop thicker fat layers under their skin for better insulation, is this an example of microevolution or macroevolution?
|
microevoultion
|
|
From a genetic point of view, what is the main difference between microevolution and macroevolution
|
The Geological collumn-This data is inconclusive as far as macroevolution is concerned
The fossil record-This data is strong evidence against macroevolution structural homology- This data is strong evidence against macroevolution Molecular-This data is strong evidence against macroevolution |
|
Name two creatures that macroevolutionists claim are intermediate links and why they are not really intermediate links.
|
Australopithecus afarensis is supposed to be an intermideate link between man and ape. However every bone that we have found of this creature indicates it is an ape. Thus, it is safest to assume that it is an ape. Archaeopteryx is supposed to link birds and reptiles, but once again the fossils tell us it is just a bird.
|
|
What is the Cambrian Explosion? Why is it a problem for macroevolution?
|
Every major animal phylum in creation can be found in Cambrian Rock. It present 2 problems for macroevolution 1) There is no way macroevolutionists can understand how macroevolution proceeded so quickly during those times 2) There are just no intermindit links
|
|
What are the four ways a bacterium can become resistant to an antibiotic?
|
conjugation, transformation, transduction, or mutation
|
|
If a bacterium has a mutation that makes it resistant to an antibiotic, does information get added to its genetic code?
|
No information is needed
|
|
Consider the following amino acid sequences that make up a small portion of a protein:

Gly-Leu-Phe-Gly-Arg-Lys-Ser-Gly-Glu(NH2)-Gly-Glu(NH2)-Ala-Arg-Lys c.Leu-Ile-Gly-Gly-Arg-His-Ser-Gly-Glu(NH2)-Ala-Glu(NH2)-Arg-Arg-Arg Which protein would you expect to be the most simular to a protein with the following subset of amino acids? |
the protein in C is most simular
|
|
based on macroevolutionary assumptions, which organism's cytochrome C should most resemble that of a yeast: a kangaroo or a bacterium?
|
a bacteriums cytochrome C
|
|
What main problem with Darwin's hypothesis did neo-Darwinism hope to solve?
|
Neo-Darwinism hoped to provide a mechanism by which information could be added to the genetic code of an organism
|
|
What problem with Darwin's hypothesis did punctuated equilibrium attempt to solve?
|
Punctuated equilibrium attempts to explain away the fact that the fossil record is devoid of any real intermediate links
|
|
How would an adherent to punctuated equilibrium explain the lack of intermediate links in the fossil record?
|
He would say that since the transformation from species to species takes such a short amount of time there is virtually no chance of an intermediate link being fossilized
|
|
What problems mentioned in this module still exists for those who believe in punctuated equilibrium?
|
Structural homology and molecelular biology still say that macroevolution could not have happened
|
|
When fruits or vegitables are imported into the U.S. from a foreign country, they are always very closley inspected for insects, even though the vasat majorty of insects are not harmful. Why is the inspection done?
|
If an insect not native to the US were carried in the country though foreign fruits and vegetables, it could ruin the balance of the US ecosystem
|
|
Name the participants in the three new symbiotic relationships that we learned in this module. Briefly describe the roles of each participant
|
The clownfish and sea anemone from a mutualistic symbiotic relationship. The clown fish is protected by the sea anemone and attracts food to it. The goby and the blind shrimp have a mutualistic symbiotic relationship in which the goby protects the blind shrimp and the blind shrimp provides a home for the goby. The oriental sweetlips and blue streak wrasse form a mutualistic symbiotic relationship in which the sweetlips gets its teeth cleaned by the wrasse and the wrasse gets food from the sweet lips
|
|
What fundamental assumption of macroevolution does mutualism seem to contradict?
|
Mutalism seems to contradict the idea that organisms always battle for survival
|
|
In the water cycle of an ocean shore ecosystem, more water evaporates from the ocean than falls back into the ocean in the form of rain. Why doesnt the ocean lose water?
|
Because the land gets the excess water and that excess water flows back into the ocean via surface runoff
|
|
What does the water cycle accomplish besides balancing the water in an ecosystem?
|
it transports nutrients
|
|
What is the possible consequence if deforestation occurs in a watershed?
|
to many nutrients will flow into the river or stream, throwing off the ecosystem
|
|
What is the principal means by which oxygen is taken from the air? What is the principal means by which it is restored to the air?
|
Oxygen taken from the air principally by respiration and restored principally by photosynthesis
|
|
Name the other way the oxygen is removed by the air.
|
Oxygen is also removed from the air by fire, ozone, formation, the rusting, and minerals.
|
|
Name the other ways that oxygen is replenished in the air.
|
by ozone destruction and the water vapor destruction
|
|
Name the ways in which carbon dioxide is removed from the air.
|
by photosynthesis and by dissolving in the ocean
|
|
Name the ways in which carbon dioxide is replenished in the air.

|
Is human-produced global warming occuring now?
|
no
|
|
What is nitrogen fixation? What type of organisms perform it?
|
Nitrogen fixation is the process by which nitrogen gas from the atmosphere is converted into nitrogen containing molecules that are useful to mist of organisms in creation. Nitrogen-fixing bacteria perform it.
|
|
What two ways does the nitrogen in organisms get put back into the environment?
|
Organisms emit some nitrogen in their wastes and the rest is turned back into useful forms of nitrogen by the decomposes that feed on their decaying remains
