99. ____________________ is responsible for the creation of new species over time. Evolution

101. By what criteria did Linnaeus establish his classificatory system?
Linnaeus based his classification on body structure, body function, and sequence of body growth.

102. Distinguish analogies from homologies.
Analogies identify anatomical features of similar function across species and homologies are structures possessed by two different organisms that arise in similar fashion and pass through similar stages during embryonic development but which have different functions.
103. Describe the theory of natural selection.
There exists natural variation and the capacity for population to exceed capacity; thus, there is a struggle for existence in which nature selects the most advantageous variations so that species can evolve.
104. What were the problems that plagued Darwin's theory of natural selection throughout his career?
The two problems were to explain how variation arose in the first place, and what the mechanism of heredity between generations was.
105. Describe Mendel's "law of segregation."
This law states that pairs of genes separate and keep their individuality and are passed on to the next generation, unaltered.
106. Distinguish between genotype and phenotype.
Genotype is the genetic composition for a trait, while the phenotype is the expressed physical characteristic.
107. Choose one kind of evolutionary force and describe it.
Students may choose and describe mutation, gene flow, genetic drift, or natural selection.
108. What is adaptation and what is its role in natural selection?
Adaptation is a series of beneficial adjustments to the environment which can change the organism over time.

109. What is sickle-cell anemia and how is it adaptive?
This is a disease of mis-shapen red blood cells that clog the circulatory system. It is primarily carried by those of African ancestry who come from areas where malaria rates are high and carriers of sickle cell have an ability to better survive malaria.
110. Describe some of the genetic variation that is most common to people native to colder regions of the world.
Individuals adapted to colder regions of the world tend to have bulkier bodies, a lower density of sweat glands, some circulatory system modifications, and shorter stature.
111. What are some factors that increase the frequency of gene flow?
Interbreeding, migration, geographical and social factors can increase gene flow.
112. What is evolution?
It is descent with modification in which evolutionary forces such as genetic drift, gene flow, natural selection, and mutation all work to create natural variation, the raw materials for change. It is changes in allele frequencies in populations.
113. Creationism has changed shape over the past decade. Discuss some of the major disagreements between Creationism and evolution. Has your study of evolution in this chapter changed your understanding of this debate?
Answer not provided.
114. While human populations are subject to the same laws of natural selection as other species, humans also have extensive and elaborate culture. Choose and discuss two examples of cultural processes that complicate simple environmental adaptation.
