Research

A complete understanding to what makes us humans will emerge only from a better knowledge of the full range of the understanding, competence and capability of our closest living relative, the chimpanzee. Too often claims of human uniqueness have been based on incomplete knowledge of what chimpanzees are or were based on chimpanzees living in unnatural captive conditions. To allow for a sound comparison of humans and chimpanzees, I have concentrated in my research on chimpanzees and humans living in their natural environment and solving natural challenges in their daily life. Recently, we have worked to deepen our comparative analysis of chimpanzee and bonobo differences, and implemented an ambitious project throughout Africa to increase our scant knowledge of behavioral, technical and biological differences in chimpanzees.

Conservation

Western African chimpanzees are badly threatened across their natural range and declared as critically endangered

The work of the Wild Chimpanzee Foundation that I founded in 2000 is becoming more important and we have concentrated our effort recently in promoting new protected areas to protect some of the few remaining but essential chimpanzee populations in Cote d’Ivoire, Liberia and Guinea. All scientific studies show convincingly that protected areas are the best strategy towards effective protection of great ape populations throughout their range.

Research

In recent years, I have developed an extensive approach to some of the questions I have been working on for decades to broaden our understanding of the breadth of the cultural diversity in wild chimpanzees, and in deepening our understanding of the technical intelligence skills in humans and chimpanzees. To be able to move forward on these important questions, I have been specifically working on the following areas:

1 – Cultural diversity in chimpanzees

The large “PanAfrican Chimpanzee Program” focuses on studying chimpanzee culture from all four Pan troglodytes subspecies from over 38 temporary research sites across Africa (http://panafrican.eva.mpg.de) . The program takes a holistic approach to studying chimpanzee culture and combines modern approaches like video camera traps and samples for genetic, pathogen and isotope analysis with traditional field approaches such as transects, phenology and habitat structure. The data generated by the project will have broad implications for the conservation of African primates and other sympatric species, as well as understanding the population history of chimpanzees and the factors currently affecting their distribution and survival.

Thanks to the extended video library we accumulated in the PanAfrican chimpanzee program, I have been able to analyze in detail different technical solutions adopted by different chimpanzee populations when fishing for termites from underground or aboveground nests. The technical constraints of termite fishing is limited so that individuals have the possibility to select different materials, body position and grips to fish for termites according to different nest structures. This opens the way to distinguish alternative strategies and see how much they are either due to ecological factors, or culturally based. We uncovered an impressively large number of different solutions in the populations, which emphasizes that we are still greatly underestimating behavioral and cultural diversity in chimpanzees.

2 – Technical intelligence in humans and chimpanzees

Many studies comparing humans with chimpanzees are weakened by important differences in the way the two species are compared, mainly because the chimpanzees are too often living in captivity under unnatural conditions. Since it often very difficult to ascertain which of the many differences are responsible for any differences observed, we are too often left wondering what one can conclude from such studies. In an attempt to overcome such biases I initiated several comparative studies.

In a first study on technology use, I followed the Mbendjele and Aka forest hunter-gatherers in the forest of the Central African Republic and the Republic of Congo, as they cracked open nuts of the same or very similar species as I studied in the Taï chimpanzees. This allowed us for the first time to directly compare humans and chimpanzees naturally performing a very similar technique, avoiding thereby the artificiality and arbitrariness of many comparative studies. In the first analysis, I compared the adult female techniques of the three groups (Boesch et al. in press) and could see that women, thanks to their human specific tools, could gain access to nuts that the chimpanzees cannot exploit. On the other hand, for the same type of nuts, chimpanzees proved surprisingly efficient and were by some measures more efficient that humans. This shows clearly that chimpanzee possess some high level of technical intelligence and can solve technical problems in ways similar and complementary to those of humans.

In a second study, we will be looking at the acquisition of the nut-cracking skills in youngsters by comparing the Mbendjele people with the Taï chimpanzees and compare maternal interventions in the learning process of the youngster and if they contribute to make the learning more efficient and more rapid. In both species, it takes many years to reach adult proficiency and this lengthy learning process should allow us to uncover more of the development of this technique.

In collaboration with Karline Janmaat and Haneul Jang we are evaluating the spatial skills of the Mbendjele people as they forage for fruits, tubers, nuts and honey in the forest and will compare with very similar methods to our studies of the spatial skills in Taï chimpanzees. Thus in two different cognitive domains, are we going to be able to compare the two species in a natural context.

3 – Tool use in wild chimpanzees

Tool use has been a key benchmark for humanity and therefore study of tool use in animals is of special relevance. In recent years, my efforts have been encompassed three different directions:

  1. Document new tool use types: Using the important video material we collected on 38 different and new chimpanzee populations in the context of the “Pan African Chimpanzee Program”, we have come upon totally unknown tool use behavior that we were able to describe in some details. The first was stone throwing and accumulation that we discovered in some West African chimpanzee populations (Kühl et al. 2016), whereby they throw stones at tree trunks during their pant-hoot display and in some cases this results in the accumulation of stones within the tree trunk. The second was algae fishing with long sticks from deep in the water of small rivers that we discovered in chimpanzees from Guinea (Boesch et al. 2016).
  2. Follow the learning skills: With two projects are we going to address the question of maternal interventions in the learning of tool use in chimpanzees. First, Katie Corogenes is focusing on nut cracking by detailing all the interactions between mothers and infants from video recordings done over three seasons. Second, Vittoria Estienne is analysing data collected with video-traps from the unhabituated chimpanzees of Loango National Park in Gabon to see how much mothers actively or passively influence the learning by offspring. Both projects will provide insights into the interaction between teaching and learning in chimpanzees.
  3. Documenting tool-use complexity: Nut-cracking has been proposed to be one of the most complex forms of tool use in animals, and with Giulia Sirianni, we have been documenting very precisely how chimpanzees select and use their tools in the forest. Although potential hammers are over-abundant in the forest, chimpanzees optimally select their hammers by responding conditionally to the situation by considering five different physical properties (Sirianni et al. 2015). Such complex tool selection was not found in capuchin monkeys (Visalberghi et al. 2016). The extraction of honey from underground hives in Loango chimpanzees in Gabon also revealed a surprising flexibility and complexity that seemed unsurpassed when comparing with all other tool use known in chimpanzees (Estienne et al. 2016, in revision).

4 – Conservation and Conservation Biology

When working in Taï national park, I realized directly how the forest has become an island within a large cocoa and coffee plantation and that the forest would disappear without actions to promote its protection. Because of the need to have an NGO active in West Africa and specifically aimed at helping the chimpanzees, I created the wild chimpanzee foundation. Please visit www.wildchimps.org to see in detail what we are doing to help.

At the same time, too often conservation is done without the knowledge of animal population abundance and the impact of conservation measures. Presently, we are trying to develop a new method based on camera-traps to follow more precisely population trends in large mammals, including chimpanzees, My student, Noémie Cappelle, is for one year collecting very precise data in the Taï National Park to provide the necessary information for a robust and precise method that will allow then to guide our conservation activities.

Large populations are becoming rarer to find and so we are faced with the challenge of assessing the feasibility of conservation projects targeting fragmented populations. In Guinea, chimpanzees are still quite frequent but often in very fragmented populations. Is it possible to protect them? When yes, what type of fragments and actions should we perform. My student, Marie-Lyne Despres-Einspenner, is going to look into these questions.

January 27, 2010: Altruism in Forest Chimpanzees: The Case of Adoption

Max Planck researchers report 18 cases of adoption of orphaned youngsters by group members in Taï forest chimpanzees. Half of the orphans were adopted by males.
These observations reveal that, under the appropriate socio-ecologic conditions, chimpanzees care for unrelated group members and that altruism is more extensive in wild populations than was suggested by captive studies.

February 13, 2007: The Chimpanzee Stone Age

Researchers have found evidence that chimpanzees from West Africa were cracking nuts with stone tools before the advent of agriculture, thousands of years ago. The result suggests chimpanzees developed this behaviour on their own, or even that stone tool use was a trait inherited from our common ancestor. Julio Mercader, Christophe Boesch and colleagues found the stones at the Noulo site in Côte d’Ivoire, the only known prehistoric chimpanzee settlement.

The Pan African Programme (PanAf)

The Pan African Programme (PanAf) ‘The Cultured Chimpanzee’ aims to overcome some of these limitations by studying a large number of populations with a cross-sectional sampling approach. It will quantify a broad spectrum of the ecological parameters that possibly contribute to generating behavioural diversity in chimpanzees and will thus also evaluate potential evolutionary scenarios to decipher central questions of human cultural evolution.

http://panafrican.eva.mpg.de/

Chimp&See

Chimp&See is a web-based platform where enthusiastic amateur researchers can watch and document the contents of the PanAf remote camera trap videos. We have collected nearly 7,000 hours of footage, reflecting various chimpanzee habitats, from camera traps in 15 countries across Africa. By scanning the videos from these traps and identifying the types of species and activity that you see, you’ll help us to understand the lives of these apes – their behaviors, relationships, and environments – and to extrapolate new ideas about human origins.

Wild Chimpanzee Foundation (WCF)

The Wild Chimpanzee Foundation is working to save between 20,000 and 25, 000 of the remaining wild chimpanzees. Current estimates suggest that there may be fewer than 100,000 chimpanzees living in seventeen different countries in Africa.

Max Planck Institute, Department of Primatology

The Department of Primatology observes apes in their natural habitats, and investigates issues related to the evolution of social systems and social behavior, cultural differences and reproductive strategies in apes. The scientists are interested in fundamental cognitive processes like communication, cooperation, conflict solving strategies, social learning in apes and humans.
