Summary Introduction
Introduction:
Kin selection is a strategy that favors the reproductive success of an animal’s kin or relatives even at the cost of the self-survival and reproduction. This sacrificing behavior towards kin is called as altruism. The evolution of kin altruism which is a sacrificing behavior is driven by kin selection.

In Biology of Beauty, Cowley found that contemporaryfemales are attracted to males with broad foreheads and strong chins, and that this effect persisted across different cultures. How did Cowley explain this result?
A. This is a trick question- this attraction is culturally relative
B. Males compete for access to females by developing these features as a form of male-male competition
C. There is no evidence that females really are differentially attracted to males with these features
D. Attraction to males with these features is adaptive for females because males with these traits are usually sexually mature and have healthy immune systems
E. Only some human cultures value these traits as attractive.
Give one example each that demonstrate the following: (provide pictures).
a. Aggression
b. Polygyny
