Primate Profile: Baboons



Scholars who strive to learn more about human evolution from both the biological and cultural perspective often turn to multiple lines of evidence, including fossil and archaeological evidence and studies of some human groups and nonhuman primates.   The study of behavior patterns of nonhuman primates provides a means of inferring about human ancestor behavior patterns, but the study of primates is not just about making inferences about the past.  Other areas of study are gained through the study of primates, including an understanding of the foundations of culture and clarifying the nature vs. nurture debate.  Today’s blog post is dedicated to informing the public about some of the behavior patterns of one primate species: baboons.


Baboons (Source: http://www.nbcnews.com/id/42013467/ns/technology_and_science-science/#.Uucg1bTTnIU)
 
Baboons live in the Savannah of Africa.  Scholarly evidence demonstrates that baboons, particularly males, have individual identities and differential social power.  Some males have been observed as leaders and some as subordinates, and of the subordinates, there are those who are submissive to females in the group.  Males tend to be leaders of the group, but that is after they have proven themselves as capable leaders as it is the primary responsibility of leaders to protect the group from other baboons (outsiders) and predators (such as lions).  The remaining males fall into a dominance hierarchy in the group.  These groups are based on “networks for social alliances”, which are friends between males and females, males and males, and females and females.  The strength of the friendship defines how far members of that friendship are willing to go for one another.  For example, a male baboon that has a strong friendship with a female baboon that is not his sexual partner may watch over her infant or provides it with food if she is unable to acquire the food herself.  It is hypothesized that these friendship are what aid baboons in finding reproductive partners, but they also must serve as a means of solidifying social bonds within the group.  Differential social positions, or friendships, exist much how they exist in human society as an individual’s experience, skill, manipulation skills, and ability to mobilize others all play a role in how one goes about acquiring friends and partnerships. 

The core of every baboon group is the subgroup of related females.  In baboon societies, males will leave the group and find another in which they can join and of which they can become a reputable citizen.  Females, however, do not leave the group and instead keep propagating the group by being reproductive members of the society with outsiders.  Most tensions in a group revolve around the outsider reproductive males wishing to join the group by courting and eventually impregnating one of the original females of the group.  Males must show their prowess to females in order to be chosen as mates.  The only time a male can act in this way toward females is when females are in estrus, the period in which a female is fertile that is demonstrated through specific biological, such as swelling of genital area.  We also know this process as “going into heat”.    

Through the study of baboons, scholars have gained a better understanding of social structures, particularly family units, for all primates.  Through the study of baboons and other primates, scholars have learned that the social and familial structures present in human groups are not inherent but are very much socially constructed.

Does the leader have to constantly worry about being stripped of or challenged for his position? Or is it pretty much once they have established themselves they are left to defend the group? It seems like it would be safer for the group if they didn't have to worry about internal struggles but still it happens with other animals and even within groups of people.

Yes and no, Brittnee. Normally, a fight for leadership will end with severe injury or death of any primate as the leader has to demonstrate that they have the physical prowess to defend the group, so these challenges are not entered into without some forethought and consideration. As noted in the post, males will leave the group in part to avoid this sort of conflict and enter another group based on the new leader's acceptance of them or the males will create their own group. It's both about gene flow and social cohesion-a delicate balance that is maintained to perpetuate the species.

I think it's awesome how the females never leave their groups, and their social behavior is very odd but invigorating!

I have watched shows were baboons are depicted as savages that attack pretty much anything that moves, and because of that influence that I had when I was younger, my perception to this group of primates was a negative. It is great that my understanding to this species has broadened, and I now have some understanding as to why baboons do what they do. Interesting blog Dr. Boston.

The social structure of baboon groups seems similar to human social groupings. There is a leader, and alpha male, who is designated the protector. The females are the core because they are the continuation of the group through reproduction with outside males. Males who desire a "relationship" with a female of the group must assimilate into the group, which causes social tensions within the group. I also find the friendship aspect fascinating. A male will befriend a female who is not his sexual partner, and help her when she is busy caring for an infant. The social organization of a baboon group is what makes it all work, and allows the group to proliferate.

Most males in a society want to be the leader or one in charge of a group. It gives them mental power and confidence in themselves of being masculine. Can an outsider come into a group of baboons and become the leader through achieved status, or must it be within the original group?

You are applying human concepts on nonhuman primates. Nonhuman primates do not acknowledge or understand social status. As for outsider males asserting dominance I know it can and does happen in other primate species, so it might happen with baboons, as well. If you are interested in learning more I suggest doing some research on the topic. :)

They are great creatures as long as you don't have to live with them as neighbors!

This is interesting that the males, once they demonstrate dominance are seldom challenged. Another point is how the friendships could be tied to humans and how we will make friendships with females if only to reproduce.

This is very informative and I personally though that scientist and anthropolgists would use monkeys to observe before baboons. I think I am confused though, because I believe that we did not evolve from monkeys (as stated in our textbook), and there is a missing link which we have yet to figure out. So I guess the answer to my question is that they are studying the animals to better understand their nature and actions, rather than how they relate to humans?

Apes where the ones who fought for position right? "The leader."
I like that these animals, have fun and interact like humans. Its weird in a way because they can't talk, but seeing their gestures. We can pick up their interactions.

Seem as if the baboon's are similar to us humans. Just due to how the males are the ones that are the protectors,which is no surprise because other primates are similar to humans. This blog is very interesting.
