Document Summary
Group consists of: single adult male, several adult females, and immature offspring. Bachelors wander until can depose a dominant male in harem. Greater dominance has greater access to females (genes passed down, many offspring) Groups tend to be dominated by single large male. Important evolutionary development (males learn to live together and cooperate for defense and develop new means of directing aggressive behaviour into less then fatal encounters) Development of submissive male behaviour (allow lower ranking males) Allows lower ranking males to remain in group, occasionally have access to females and increase their fitness (need to get genes into next generation) When on move males form defensive perimeter and females in middle to protect young. Every male has a harem of adult females. Living together, but in small groups within by themselves. Males trying to attract females to form a harem from other groups. Not hierarchy among males (don"t fight each other)
