Match the term at left with the best description at right.

Draggable item		Corresponding Item
descent with modification		an explanation for a phenomenon supported by a large body of scientific evidence
scientific theory		formation of new species
speciation		ancestral organisms pass down inherited traits which which were beneficial to their offspring
natural selection		any inherited characteristic that helps a species survive in its environment
adaptation		the gradual change in a population/species over time
evolution		variation --> overproduction --> competition --> descent with modification

3

Which statement accurately describes how natural selection leads to the evolution of a species?

3

A zoologist finds that in the populations of frogs found in MacGregor’s pond, half the genes for skin color in the gene pool were alleles for green spots, and half of the genes were alleles for brown spots. Which of the following could cause these proportions to change?

3

What is the most logical reason that two organisms would have identical cytochrome-C protein
sequences yet are different species?

3

What would be the best judge of a wolf’s fitness?

3

Each column in the chart represents a different population of the same insect species. Which row shows the population with the greatest chance of survival in a changing environment?

3

Within a decade of the introduction of a new antibiotic, nearly all of the original bacteria it was designed to treat are resistant to the antibiotic, so researchers now have to develop a new antibiotic to treat this bacteria. What is the most likely explanation for this change?

2

As seen in the image below, scientists note that despite performing the same functions, the structures of these wings are very different, and evolved independently. These are referred to as ________________ .

3

Caffeine (seen above) is a chemical compound found in the seeds of many different plants, such as coffee beans, cola nuts, and cacao beans (the source of chocolate!). The presence of this biochemical in all three types of plants suggests that these plants…

3

The chart to the right analyzes the differences in the hemoglobin proteins of several different vertebrate animals. This is an example of _______________ evidence and allows us to conclude that which two animals are most closely related in terms of evolutionary history?

3

When a paramecium, a single-celled eukaryotic organism, is living under stressful conditions, it sometimes switches from asexual to sexual reproduction. The evolutionary advantage of sexual reproduction is

3

Speciation, the formation of a new species, can occur as a result of

3

Sometimes unrelated species evolve similar traits, despite living in different parts of the world and evolving from separate ancestors. One such example would be the similar adaptations of the North American Wolf and the Marsupial Tasmanian Wolf of Australian. This is known as

3

The right side of the diagram below illustrates which rate of speciation?

2

The left side of the above diagram suggests that several species of birds evolved from a single common ancestor, as a result of changing environmental conditions. This describes which of the following types of evolution?

2

Scientists believe that most evolutionary change takes place in small steps of continuous change. This is known as

Look at the images and read the passage below in order to answer the question that follows.

The image above shows the two forms of the moth Biston betularia, a dark colored form and a light colored form. Prior to the industrial revolution, the trees in England were very light colored and only light colored moths were recorded. Following the Industrial Revolution of the 18th Century, however, a great deal of soot has been deposited on the country side around industrial areas. The soot darkened the surfaces of trees and rocks. In 1848, a dark-colored moth was first recorded. Today, in some areas, 90% or more of the-peppered moths are dark in color. More than 70 species of moth in England have undergone a change from light to dark. Similar observations have been made in other industrial nations, including the United States.
Based on your reading, which of the following best explains why so many dark colored moths appeared following the Industrial Revolution?
