The Iroquois Indians lived in peace for hundreds of years as a hunting nation, but in the seventeenth century, trade introduced by Europeans brought the Iroquois into competition with a neighboring tribe. A series of tribal wars developed, and the Iroquois ultimately became ferocious and successful warriors. This series of events suggest that:

a. warlike behavior is the result of uncontrollable aggressive instincts.

b. competition inevitably leads to violence.

c. changing social conditions can lead to changes in aggressive behavior.

d. aggressive behavior ensures evolutionary survival.
