Exam 3: Evolution by Natural Selection

In the accompanying figure of Jones and Reithel's work with snapdragons,what is the most likely outcome if these plants were in a natural setting?

Proponents of ________ [two words] argue that the complexities of living systems can only be accounted for by the creative acts of a conscious entity.

Which of the following statements best summarizes natural selection?

________,in general terms,is an individual's ability to survive and reproduce.

Darwin studied and wrote extensively about the mechanism known as artificial selection.Artificial selection is similar to natural selection,except that ________.

Varieties produced under domestication via artificial selection most generally have traits that ________.

Identify and describe Darwin/Wallace's four tenets of natural selection.

When the Darwin/Wallace theory of natural selection is summarized,four central postulates emerge.Which of the following is NOT one of these four natural selection postulates?

Compare and contrast the experimental work of Jones and Reithel on snapdragons with Peter and Rosemary Grant's research with the medium ground finch (Geospiza fortis).

Regarding the nature of natural selection,which of the following is NOT an accurate statement?

Social,political,and legal controversy surrounding acceptance of evolution goes back to the decade of the ________,when teacher John Scopes was tried for teaching evolution.

Evolution by natural selection ________.

Darwin's calculations on elephant reproduction under ideal conditions reveal that far more elephants could be produced than actually are.Explain why this supporting fact is important to the theory of natural selection.

The accompanying figure shows data on composite values for beak size,beak shape,and body size for the medium ground finch (Geospiza fortis)inhabiting Daphne Major.Complete data sets were collected from 1973 onward. For each of the three graphs in the accompanying figure,the 95% confidence intervals are shown as vertical bars extending above and below each data point for each year.The fact that many of these 95% confidence intervals do not overlap with the data from 1973 (the original reference point for this study)do not overlap reveals that ________.

Rewrite Darwin/Wallace's four tenets of natural selection by incorporating what we've learned from the field of genetics (i.e.,"The Modern Synthesis").

Darwin confirmed the concept of evolution under domestication himself by experimenting with pigeons.This mechanism is more commonly known as ________.[two words]

Darwin developed his theory of natural selection despite having an incomplete and/or inaccurate knowledge base from which to work.Which of the following were problems for Darwin?

Which of the following U.S.Supreme Court decisions struck down laws prohibiting the teaching of evolution?

Before Mendel's work was rediscovered,some argued that natural selection would not work because favorable traits would merge into existing traits over time and become lost.This hypothesis is known as ________.[two words]

Tomatoes carry a gene called fw2.2 that encodes a protein made during early fruit development―the job of which is to repress cell division.Additionally,researchers have identified a second gene called fas that controls the number of compartments in the mature fruit.Artificial selection leading to the production of very large tomatoes has apparently capitalized on ________.
