background image Study Guide for Exam 1 How Scientist Discover Truth 1. What is meant by the “Special Creation”?  How was life created according to the Special  Creation”? a. According to the Special Creation, everything was created in one location and for one  purpose.  Everything exists in the way it was created and there is no such thing as  change, evolution, adaptation, or anything of the sort.   2. Did early naturalist adequately consider and investigate the ideas of the special creation?  Yes, for example Darwin.  Darwin studied specimens with a strong belief in the Special Creation.  He  was studying to be a priest and when he began to see organisms which contradicted the beliefs of the Special Creation, he kept searching.  3. Describe the source of conflict between science and religion. Truth.  Truth is at the base of each rift between science and religion. 4. Differentiate between Rationalism and Empiricism.  How do they work together in science? Rationalism is about having beliefs that are based purely on reasoning and emotional response.   Empiricism is about having beliefs that are based purely on observational experiences. 5. Why was there so much scientific knowledge lost during the medieval period? There was a revolt and many books were destroyed and people were not educated.

A theory is an explanation of an observed occurrence in the world.  A hypothesis is a theory which needs  to be tested.  Scientific law is something that has been proven time and time again and always occurs  under the same circumstances.     7. What is the connection between predictions and hypotheses? The prediction fuels the hypotheses.  A hypothesis takes a prediction and places a condition on it to test  for a specific result.  It’s like giving an action to a statement.   Questions for Microevolution: 1. Define the following words:  Population, genotype, phenotype, gene, allele, gene pool and  microevolution. a. Population: an inbreeding group in a particular geographical location b. Genotype: the genetic makeup of an organism c. Phenotype: the physical appearance of that genetic makeup of an organism d. Gene fragments of DNA that determine specific traits  e. Allele: alternative forms in specific genes  f. Gene Pool: genes found in a given population g. Microevolution: the study of which alleles are found in a population and how the  frequency of those alleles change over time 2. In Biology, we talk about organisms evolving.  What does that mean? What is it that is actually  evolve? We are talking about how populations NOT individuals evolve.  We are studying how nature determines  which alleles in a gene become more frequent, which traits “die off”, etc.   3. Define microevolution. Microevolution is the study of how allele frequency in a population’s gene pool changes throughout the  generations for the improvement of the species. 4. What are the 5 mechanisms or agents that drive micro­evolution?

What is the source for all new alleles? (Another way of asking this is “what is the only means by  which new genetic information comes into being?”) Mutation 6. Understand the theory of Natural selection and be able to identify an example of it.  a. The theory of Natural selection is often summed up as “Survival of the Fittest.”  Who are  deemed the fittest?  What special trait do they have? The fittest creatures are those who have characteristics which aide their survival.  Natural selection takes  that trait and gradually, it becomes more popular in a given population.  For example, when the first grand extinction occurred and sea life was at risk, some of those animals developed traits which allowed them to survive on land, allowing flora and fauna to continue on in life. 7. How does sexual selection differ from natural selection? Sexual selection is specifically for traits that would help to increase the individual’s chances of procreation and doesn’t necessarily aid in its survival. 8. Give an example of sexual selection. The now extinct European Elk had huge antlers because the females found it attractive.  However, some  of the antlers would extend even past eight feet and these elk lived in a forest area in Europe, where  hunting for sport was very popular.  They were hunted into extinction because the antlers didn’t provide  any camouflage or agility. 9. What is the main factor that determines whether a new allele will become more common in the  population? An allele becomes more popular if it helps the population in some way, either with survival of the fittest or  with sexual selection. 10. Why is genetic drift most powerful in small populations? Smaller populations means that one slight change will have a larger affect.  When there is a population of  ten and one has a mutation, we can say that ten percent of the population is mutated.  When there is a  population of a hundred and one has a mutation, then only one percent of the population is mutated. 11. Would you expect a population established by the founder effect to have more or less variety than the original population?
