Ape human sex-Why did humans evolve big penises but small testicles?

We use cookies to improve our service for you. A new study has revealed the extent to which male apes use sexual intimidation to control their mates. Repeated aggression without cause appears to put females under constant pressure, to make them compliant when the male feels it's time for sexual intercourse. These recent findings "question the extent of sexual freedom left for females in such societies," Baniel suggests. The researchers investigated two wild large chacma baboon groups at Tsaobis Nature Park in Namibia over a period of four years.

We often look to the behavior of chimpanzees and bonobos to infer the behavior of our ancestors. For example, male coalitionary aggression in chimpanzees is often taken to indicate violent tendencies in humans. Comparative data on bonobos provide a different picture that emphasizes peace and non-violence. However, both species have similar social structures. Males reside in the group their entire lives, females typically disperse and must integrate into a new community, and both have highly flexible, fission-fusion dynamics, in which animals join subgroups that frequently change.

Although data from wild populations indicate sex-typical patterns of social bonds, understanding the extent to which captive groups exhibit those patterns can illuminate whether those sex differences are innate.

With my colleague, Emily Boeving, I examined whether captive male and female chimpanzees and bonobos have the sex-typical social bonds we would expect from wild populations. This means that female chimpanzees typically have less time and opportunities for socializing, though this varies quite a bit across chimpanzee habitats. This allows them to socialize easily. But in captivity, where neither species is limited by food resources, would they form the same sort of sex-typical social bonds?

To answer this question, we studied grooming networks in captive bonobos at the Columbus Zoo, and captive chimpanzees at the North Carolina Zoo. We used social network analysis, which uses mathematical modeling to look at group-level patterns of social relationships. We compared the social network position of males versus females and the frequency of same-sex versus opposite-sex grooming bouts. We found that males and females in both species have similar social network positions, and that grooming is distributed equally between same-sex and opposite-sex pairs.

This suggests that in the absence of ecological constraints, chimpanzees and bonobos are equally friendly with male and female social partners. However, we also looked at individual factors that influence social bonds. We compared social network position of wild-born versus captive-born animals, history in the group, and kinship.

In chimpanzees, none of these individual factors were associated with social network position. There are two possible interpretations. One is that wild-born individuals may have greater social skills than captive-born individuals.

Captive chimpanzees reared away from their mothers are less extroverted , and less interested in grooming. However, the key variable there is being reared apart from mothers—in the bonobo group, all captive animals were mother-reared. The other possible interpretation is their social position was due to their age and long residence in the group. Since origin, age, and group residence are all conflated in this group, we cannot tease these variables apart.

However, residence in the group might be analogous to the position that older females, and all males, hold in wild populations. Our findings suggest that both chimpanzees and bonobos have a high degree of flexibility in their social bonds, which may be due to their fission-fusion social dynamics. The flexible grouping patterns allow them to change social groups frequently, which allows wild populations to quickly adapt to changing ecological conditions.

Such flexibility means that rather than having innate tendencies toward certain grouping patterns, animals have social flexibility that is shaped by their environment. Their choice of friends may be driven by factors such as group residence, as well as other factors we could not account for, such as personality.

Rather than being from Mars or from Venus, both chimpanzees and bonobos are unique individual Earthlings with complex social lives. Like our closest relatives, humans also evolved within fission-fusion societies with complex social dynamics. Similarly, rather than having rigid patterns based on sex-typical behavior, our own behavioral biology is complicated.

These recent findings "question the extent of sexual freedom left for females in such societies," Baniel suggests. The researchers investigated two wild large chacma baboon groups at Tsaobis Nature Park in Namibia over a period of four years. A male might also chase a female up a tree and push her onto thin branches, co-author Elise Huchard of the University of Montpellier, France, tells DW. The female gets stuck there, where the male continues to harrass her for several minutes.

It is very nasty. Observations ruled out that these copulations were motivated by a general preference of females for aggressive males - something which does occur in many other species.

With baboons showing the same behavior, the researchers suggest sexual intimidation might be a common trait in primates living in large groups - particularly when males are typically larger than females. That resembles a bit what happens with domestic violence in humans. But Huchard stresses that this hypothesis would have to be confirmed in further studies.

All seven species of great apes share the following characteristics: no tail, a large skull with a large brain, a curved spine and an opposable or prehensile thumb. Like the chimpanzee, which is at home in central Africa and known for its often aggressive behavior. The Bonobo, or pygmy chimpanzee, is a really peaceable ape. Bonobos use frequent sex to ease tension in the group; they are also into French kissing and oral sex.

Bonobos only live in the Democatic Republic of Congo. There are two species of orangutans: one lives on the island of Borneo, the other on Sumatra. Both live on trees, have very long arms and hand-like feet that they use for climbing. Bornean orangutans are squat, they are heavier than their cousins on Sumatra, and their fur is darker and longer. Sumatra orangutans also spend less time on the ground than their Bornean cousins. Experts suspect the reason to stay aloft may be the Sumatra tiger, which also preys on orangutans.

Gorillas are subdivided into two subspecies, the Eastern and the Western gorilla. The Eastern gorilla is bigger, its fur is darker, and the species is subdivided even further into the Eastern lowland and the Mountain gorilla photo. The Western gorilla is also subdivided, into the Western lowland photo and the profoundly endangered Cross River gorilla. The former also live in smaller groups. Is there a great ape missing?
