Document Summary
Female philopatric: mating system polgynandry ( multi male/multi female) If similar coloured testicles, males are closer in rank (mandujoules) If a male falls in rank, his testicles lose dark blue hue and become light blue. If 2 unfamiliar males are introduced, the one with the darker testicles will be dominate. Live in 1-male group (one-male units) in the highlands of ethiopia, africa ( very cold: also some all-male groups (bachelor groups, mating system polygyny. Hour glass male and female characteristic: females have white vesicles on the chest & necks that enlarge during estrus (pearl necklace ) Slide 3: hypothesized that chest patched evolved because colour on the rump would rarely be seen. Slide 4: sexually dimorphic species-males are larger than females; males have enlarged canines and a huge man of hair (a cape of hair)- when you see large male and small female there is completion over female.
