TOPICS FOR EXAMINATION I - Biology 1407, CAMPBELL AND REESE 10 th ed.
Also you should KNOW AND UNDERSTAND ALL TOPICS AS A FUNCTION OF THE CONCEPT
CHECK HEADINGS IN YOUR TEXT!!
THIS WILL BE A CHALLENGING EXAM!! BE PREPARED TO THINK!!!
This topic sheet is modified from one developed by Dr. D. Schwartz, HCC, SW.
CHAPTER 22
What is Lamarckian evolution, and how is it similar to and different from Darwinian evolution? Be able to recognize a Lamarckian example when you see one. Know and understand the concept of natural selection. KNOW THE OBSERVATIONS AND INFERENCES ASSOCIATED WITH DARWIN'S
PRINCIPLES OF EVOLUTION BY NATURAL SELECTION, AS OUTLINED IN YOUR
TEXTBOOK . What is artificial selection? Is Darwinian evolution directed or does it happen by chance?
Know and understand how to apply these concepts to evolutionary situations and problems presented to you.
CHAPTER 23
What are the requirements for Hardy-Weinberg equilibrium? Know all 5 ways that these requirements can be invalidated. BE ABLE TO CALCULATE ALLELE AND GENOTYPE FREQUENCIES IN
HARDY-WEINBERG PROBLEMS. (Bring a calculator to the exam, capable of performing squares and square roots. DO NOT BRING ANY DEVICE CAPABLE OF DISPLAYING WORDS
OR LETTERS!!!! YOU WILL NOT BE ALLOWED TO USE IT!!!! NUMERICAL DISPLAY
ONLY!!!!) WHAT IS MICROEVOLUTION? What is Darwinian fitness? What is the one important purpose of diploidy? What are the reasons why natural selection cannot fashion a "perfect" organism?
What is our modern understanding of evolution?
CHAPTER 24
Which is the only "natural" taxon, determined by the ability to interbreed? AKA: What is a species? How else may they be defined? Know the prezygotic and postzygotic methods of reproductive isolation.
WHAT IS ALLOPATRIC SPECIATION? WHAT IS SYMPATRIC SPECIATION? WHAT IS
THE IMPORTANT END RESULT OF BOTH KINDS OF SPECIATION MECHANISMS? HOW
ARE SPECIES KEPT GENETICALLY DISTINCT?
In addition, you are responsible for all specialized biological vocabulary not mentioned in this topic sheet.
I may ask specific questions about definitions. I will also use specialized words in questions and in answers to those questions. I will expect you to know the meaning of any biological vocabulary word which was used in lecture or laboratory, or in your reading assignments. This holds for ALL of your exams, not just this one.
