Exam 13: How Populations Evolve

Who developed a theory of evolution almost identical to Darwin's?

The variation in gene pools among the 30 pupfish populations occurred through an evolutionary mechanism called

A woman struggling with a bacterial illness is prescribed a month's supply of a potent antibiotic. She takes the antibiotic for about two weeks and feels much better. Should she save the remaining two-week supply, or should she continue taking the drug?

Aristotle believed that

A news article discussing the evolution of domestic dogs from wolves included this statement: "On its way from pack-hunting carnivore to fireside companion, dogs learned to love-or at least live on-wheat, rice, barley, corn, and potatoes." What is a more scientifically accurate way to state what happened with dogs?

Humans share several features with salamanders. Certain genes and proteins are nearly identical between the two species; both species have four limbs with a similar skeletal structure; the species' early embryos are similar; and where the salamander has a functional tail, humans have a vestigial tailbone. In evolutionary terms, these are examples of

Which of the following would prevent an organism from becoming part of the fossil record when it dies?

A group of dog breeders is trying to design and develop an ideal dog. They want a dog with a gentle disposition, black fur, long ears, short legs, and a strong sense of smell. Which of the following comments from fellow dog breeders represents the biggest challenge they are likely to face?

A population of butterflies has an allele B for big spots on the wings and b for small spots on the wings. The table below provides data about this population. Genotype BB Bb bb Number of butterflies 300 400 300 Genotype frequency 0.3 0.4 0.3 Regarding these data about the butterfly population, which of the following statements is correct?

Which of the following thinkers argued that much of human suffering was the result of human populations increasing faster than food supply, an argument that later influenced Charles Darwin's ideas of natural selection?

Mate-attracting features such as the bright plumage of a male peacock result from

After a copper smelter begins operation, local downwind populations of plants begin to adapt to the resulting air pollution. Scientists document, for example, that the acid tolerance of several plant species has increased significantly in the polluted area. This is an example of

Blue-footed boobies have webbed feet and are comically clumsy when they walk on land. Evolutionary scientists view these feet as

Frequency-dependent selection, as seen in the case of the scale-eating fish in Lake Tanganyika, tends to

The frequency of homozygous dominant individuals in a population that is in Hardy-Weinberg equilibrium is equal to

Darwin found that many of the species on the Galápagos Islands

Lyell's book Principles of Geology, which Darwin read on board the HMS Beagle, argued in favor of which of the following concepts?

Which of the following statements about evolutionary adaptation is true?

A dog breeder wishes to develop a breed that does not bark. She starts with a diverse mixture of dogs. Generation after generation, she allows only the quietest dogs to breed. After 30 years of work she has a new breed of dog with interesting traits, but on average, the dogs still bark at about the same rate as other dog breeds. Which of the following would be a logical explanation for her failure?
