BIOA 208: SEX AND EVOLUTION
Study Guide Exam 1
1. SCIENCE AND EXPLANATION
a. What are the three criteria of a good scientific explanation? Understand what each means.
a. Falsifiable predictions
b. What are proximate and ultim
Problem Set 4
1) Sexual reproduction involves two processes: meiosis and recombination.
a. Define each.
Meiosis is part of the gamete formation process that consists of chromosome conjugation
and two cell divisions. Meiosis starts with a diploid cell and
Problem Set 8
1. According to Cashdan, women want three attributes in a mate: good condition, resources,
and status. Give the evolutionary logic that explains each of these preferences.
Women want good condition in a mate because good physical condition i
Problem Set 1
1) There are many ways of appreciating and understanding the world around us. What are the
key features of a scientific understanding?
It all starts with a question, then form a hypothesis and make predictions. Then design an
Problem Set 10
1) Lets begin by defining sexual orientation.
a. What is the Kinsey Scale, and how can it be used to study sexual orientation?
The Kinsey Scale is used to measure sexual orientation based on four categories which
Problem Set 5
1) What is sexual selection? How, if at all, does it differ from natural selection?
Sexual selection are traits that are favored for mate competition but are disfavored by natural
selection. For example, a peacocks tail is showy and heavy. T
Problem Set 7
1) What variables drive sexual selection, and what is your assessment of these variables in
Humans select their mates based on genetic and non-genetic benefits; some of which include,
accesses to resources, cooperation, generosity, a
Problem Set 9
1) Many behavioral traits of men and women (e.g. certain mating preferences) should be
regarded as evolved adaptations.
a. What does the idea that such traits are adaptations require?
For a trait to be considered an adaptation it must fulfil
Problem Set 11
1) Marriage is a human universal, presumably because it serves certain fitness-related functions.
a. What are the possible benefits of marriage?
Men and women benefit differently from marriage. Men marry for sexual access to a mate, to
Problem Set 6
1) According to Daly and Wilson, why, evolutionarily, is there more violence among men than
there is among women?
The difference in violence exhibited by men and women goes back to the competition for mates.
Due to that fact that women are t
