Question for tutorial

How does sexual conflict\(^1\) lead to the evolution of secondary sexual characters\(^2\)?
\(^1\)Defined as occurring when traits favored in reproductive competition in one sex are costly for members of the other sex.
\(^2\)Defined as traits that differentiate the sexes (e.g., occur in males only) that are not directly involved in reproduction.
