The goal is to understand the evolutionary and ecological drivers of chimpanzee cultural and behavioral diversity. The PanAf also continues to analyze data collected over 8 years from 18 countries across Africa, at over 40 temporary and long-term research and conservation sites. Their findings in chimpanzees confirm that fecal samples, although more complex than blood samples, are a fine source of host DNA for any species. The researchers say they are now beginning to use the methods they’ve developed for chimpanzees with other great apes and primates.
“This is so critically important to their conservation and really argues that connectivity between forests across Western Africa, especially in the northern region, needs to be preserved for the protection of these populations and the subspecies,” said Marques-Bonet.Īnthony Agbor co-author of the study and field site manager at several PanAf sites prepares samples for processing in the field. This nicely explains why different studies aiming at reconstructing different ancestral periods have come to different conclusions about the evolutionary history of chimpanzees.”Īmong many other insights, the evidence also reveals extensive connectivity in Western chimpanzees. “Chimpanzee subspecies were indeed separated in the past but have since also experienced genetic exchange between populations. “We were able to show, using different analyses that look at very old and more recent variation, that the history of chimpanzees is complex, much like that of our own species,” says Mimi Arandjelovic, co-lead of the study from the Max Planck Institute for Evolutionary Anthropology, iDiv, and Leipzig University. They found a link between historical population structure, barriers of genetic continuity between chimpanzee populations, and geographical barriers such as rivers and lakes. The researchers use this information to design a method to link confiscated chimpanzees to their place of origin within about 100 kilometers, with the goal to support efforts to combat the illegal trade of chimpanzees and related products.įontsere says they’ve also provided a more nuanced understanding of the genetic differentiation of the four recognized chimpanzee subspecies. The catalog, which includes 828 chimp samples from across their range, offers a detailed reconstruction of chimp population structure and fine-scale patterns of isolation, migration, and connection. Scientists have produced the first catalog of genomic diversity for endangered chimpanzees in the wild, as reported today (June 1, 2022) in the journal Cell Genomics. People interested in helping protect endangered chimpanzees can annotate videos for a citizen science project called Chimp&See. This catalog allows them to link confiscated chimpanzees to their place of origin, with the goal of curtailing the illegal animal trade. Using thousands of chimp fecal samples, researchers have created the first catalog of genomic diversity for endangered chimpanzees in the wild.
