![]() Unsurprisingly, the Nigeria-Cameroon subspecies inhabits portions of Nigeria and Cameroon. The western subspecies ranges from southern Senegal to western Ghana. This species lives throughout various regions of eastern and central Africa. Many also live in mountainous regions up to 9,000 ft. Some inhabit tropical rainforests or scrub forests, others live in savannas, grasslands, woodlands, or chaparral. The different subspecies prefer different habitat types. These primates live in a variety of different ecosystems. The entire family shares a close bond even after reaching adulthood. Because of this, her older offspring often help with the care of their younger siblings. Sympatric Siblings – The female doesn’t wait until her adolescent young are fully mature to breed again.old, but they remain closely reliant on her until between the ages of 13 and 15 yrs. Their mothers wean them when they reach 3 or 4 yrs. Family Fidelity – Infants of this species take quite a long time to reach maturity.They also develop grey hairs in the midsection of their backs as well. Patchy Pelage – Not unlike some humans, as these primates age some individuals begin losing the hair on their heads.The different subspecies include the central, western, Nigeria-Cameroon, and eastern Chimpanzee The primary difference between the various subspecies is where they live. Separate Subspecies – Researchers recognize 4 different subspecies at this time. ![]() Learn about what makes these creatures so unique below. These primates are one of our closest living relatives. Females typically weigh between 60 and 110 lbs. Males usually weigh more than females at 80 – 140 lbs. tall, depending on the gender and subspecies. In lively prose, reflecting personal experience with apes in the rain forest, he compares our two closest relatives and explains the striking differences between the male- dominated and territorial chimpanzees and the female-centered gentle bonobos.They stand between 3.2 and 5.5 ft. "Takeshi Furuichi is one of very few scientists in the world familiar with both chimpanzees and bonobos. Lastly, by identifying key mechanisms of social coexistence in these two species, the author also seeks to find solutions or “hope” for the peaceful coexistence of human beings. Although they are non-related in male-philopatric society, they usually aggregate in a group, enjoy priority access to food, determine which male is the alpha male, and generally maintain much more peaceful social relations compared to chimpanzees. By evolving pseudo-estrus during their non-reproductive period, females have succeeded in moderating inter-male sexual competition, and in initiating mate selection. ![]() In contrast, female bonobos have the same or even a higher social status than males. Chimpanzees have developed social intelligence to survive severe competition among males: by upholding the hierarchy of dominance, they can usually preserve peaceful relations among group members. Chimpanzees are known as a fairly despotic species in which the males exclusively dominate over the females, and maintain a rigid hierarchy. ![]() This book describes the similarities and differences between two species, bonobos and chimpanzees, based on the three decades the author has spent studying them in the wild, and shows how the contrasting nature of these two species is also reflected in human nature. The most important differences between bonobos and chimpanzees, our closest relatives, are the social mechanisms of coexistence in group life. ![]()
