QuestionAnswer
Which of the following is a component of Darwin's original theory of evolution? Organisms whose traits fit their environments will be the best reproducers.
Which of the following is true of evolution? Evolutionary changes are often not directly observable because they occur over vast expanses of time.
Of the following structures, which is homologous to that of the wing of a bat? the forearm of a lizard
Richard Dawkins's book on the theories behind evolution is entitled "The Blind Watchmaker." What is the significance of this rather ironic title? Organisms are indeed very complex, much like a precision watch; however, evolution fashions organisms without any "forethought or plan" for their ultimate design.
During a class on evolution one of your fellow students remarks, "The giraffe stretched its neck while reaching for higher leaves; its offspring inherited longer necks as a result." To correct your fellow student's misconception, what would you say? Characteristics acquired during an organism's life are not passed on through genes.
Which of the following statements describes how evolution is a biological theme that ties all others together? Evolution explains y distantly related organisms sometimes resemble 1 another. Evolution explains the diversity of organisms. Evolution xplains how organisms become adapted to their environment.Evolution explains why organisms have common characteristic
Prior to Darwin's theory of evolution, most scientists presumed that organisms were fixed and permanent.
Which of these scientists did not believe that organisms changed over time, or evolved? Georges Cuvier
In formulating his ideas on evolution, Darwin relied on information from what other scientific disciplines? geology human population dynamics
Which of the following evidences, if it were actually discovered, would most likely cause the demise of the theory of evolution? a primate fossil in the same rock layer as a trilobite
The overall idea that is expressed by the theory of evolution is that all living things have descended from a common ancestor.
Before Darwin's theory of evolution was accepted, there was some doubt that natural selection would actually work. What was the main stumbling block in scientists' acceptance of natural selection? a misunderstanding of how traits were passed on to offspring
How do the forelimbs of a bat, whale, dog, and monkey support the theory of evolution? They all have a similar 1-2-5 bone structure, indicating they all descended from a common ancestor.
Sometimes evolutionary changes can actually be seen occurring in populations of organisms. Which of the following characteristics is required in order to see evolutionary changes take place in a population? Organisms must have rapid reproductive capability.
Richard Dawkins, a prolific writer on evolutionary theory, has stated that when it comes to the theory of evolution, scientists are really more like detectives. Why would this be so? Like scientists, detectives must formulate hypotheses and theories based on the evidence they have found.
Charles Darwin is given the credit for formulating the idea of evolution through natural selection. However, another naturalist came up with the same insight at approximately the same time as Darwin. Who was it? Alfred Russel Wallace
The effects of natural selection may be countered by gene flow
In relation to natural selection, evolution is the outcome
Moto Kimura's theory that opposed natural selection was the neutral theory
Scientists generally agree that heterozygous advantage is frequent
The occurrence of large or small beak sizes among seed crackers in the absence of medium-sized beaks is an example of disruptive selection
Even though sickle-cell anemia is usually fatal to homozygous individuals, the disease persists because: ) individuals with one allele for sickle-cell anemia are resistant to malaria
Sickle-cell trait in humans is a classic example of ____________________. the superior fitness seen in heterozygotes
A person with sickle cell trait, having one S allele and one normal, will be resistant to malaria and eventually develop sickle cell anemia. False
For a woman living in the United States, which genotype would be the most advantageous to have? homozygous for the normal hemoglobin allele
