The most critical characteristics used by taxonomists to determine whether two animals are members of the same of the same species is the

Which of the following best supports the statement that mitochondria are descendants of endosymbiotic bacteria-like cells?

The LEAST effective means of controlling pest species such as rats or roaches over a long period of time is generally to

All the following statements reguarding the Hardy-Weinberg phenomenon are correct EXCEPT:

Which of the following contributes LEAST to speciation?

In certain species crosses, such as that between the horse and the donkey, offspring are produced, but they are usually sterile. The most common explination of this result is that

A new species of organisms has evolved when

The evolution of several species from a single species, each occupying a different niche

The establishment of a genetically unique population through genetic drift

The independent development of similarities between unrelated groups resulting from adaption to similar environments

S.L Millers classic experiment demonstrates that a discharge of sparks through a mixture of gases could result in the formation of a large variety of organic compounds. All of the following gases were used in this experiment EXCEPT

Some varieties of Neisseria gonorrhoeae are now resistant to penicilin. These varietes of bacteria most probably developed as a result of

The differences in cricket calls among sympatric species of crickets are examples of

The wing of a bat, the flipper of a whale, and the forelimb of a horse appear very different, yet detailed studies reveal the presence of the same basic bone pattern. These structures are examples of

Which of the folloowing is a correct statement about mutations

Although the seal and the penguin both has streamlined, fishlike bodies with a layer of insulating fat, they are not closely related. This similarity results from

Which of the following is probably the best explination for the fact that Antartic penguins cannot fly, although there is evidence that millions of years ago their ancestors could do so?

In a certain flock of sheep, 4 percent of the population has blaqck wool and 96 percent has white wool. Assume that the population is in Hardy-Weinberg equilibrium. If black wool is a recessive trait, what percentage of the population is heterozygous for this trait?

In a certain flock of sheep, 4 percent of the population has blaqck wool and 96 percent has white wool. Assume that the population is in Hardy-Weinberg equilibrium.
What percentage of the population is homozygous for white wool?

The condition in which there are barriers to successful interbreeding between individuals of different species in the same community is referred to as

A number of different phylogenies (evolutionary trees) have been proposed by scientists. These phylogenies are useful because they can be used to

Archaeopteryx is an extinct feather reptile:

Peripatus has claws like an insect and paired nephridia like a segmented worm

Choose the field that has provided each of the following pieces of evidence that biological evolution has occurred
Most Humans diabetics can use insulin derived either from pigs or from humans

`Choose the field that has provided each of the following pieces of evidence that biological evolution has occurred
During early development, a human fetus has a tail and gill arches

Which of the following statements best expresses the concept of punctuated equilibrium

Which of the following principles is NOT part of Darwin's theory of evolution by natural selection?

In certain Native American groups, albinism due to a homozygous recessive condition in the biochemical pathway for melanin is sometimes seen. If the frequency of the allele for this condition is 0.06, which of the following is closest to the frequency of the dominant allele in this population? (assume that the population is in Hardy-Weinberg equilibrium.)

The different species of finches on the Galapagos Islands are believed to have arisen as a result of natural selection acting on populations of finches that had experienced

By discharging electric sparks into a laboratory chamber atmosphere that consisted of water vapor, hydrogen gas, mathane, and ammonia, Stanley Miller obtained data that showed that a number of organic molecules, including many amino acids, could be synthesized. Miller was attempting to model early Earth conditions as understood in the 1950's. The results of Millers experiments best support which of the following hypotheses?
