At one research center in Leipzig, Germany, years of archived experiments preserved choices made by chimpanzees, bonobos, gorillas, and orangutans.<\/p>\n
By linking those records, Dr. Alejandro S\u00e1nchez-Amaro at University of Stirling (UofS<\/a>) documented a continuous body of evidence that had been scattered across separate papers.<\/p>\n The collection spans research from 2004 through 2021, allowing the same animals to reappear across many different studies.<\/p>\n Even at that scale, the archive still needs careful comparison, because meaning does not emerge from one task alone.<\/p>\n Scale reshapes conclusions<\/p>\n Ape cognition research often turns on a handful of willing animals, so one missing participant can change the picture.<\/p>\n \u201cMost studies therefore focus on specific questions and tend to produce relatively small datasets,\u201d S\u00e1nchez-Amaro said.<\/p>\n Here, 81 apes appear in the record, and 78 of them joined more than one project.<\/p>\n Repeated participation lets scientists separate a passing animal behavior from steady patterns in learning, memory, or decision-making.<\/p>\n Files become comparable<\/p>\n The EVApeCognition Dataset gathers 262 experimental datasets from 150 publications tied to the Leipzig center studies from 2004 through 2021.<\/p>\n Curators made the records standardized<\/a>, meaning the same details appeared in the same places across files.<\/p>\n Files keep each ape\u2019s name, species, sex, role, age, test session, and trial when those facts were available to reviewers.<\/p>\n After review and author approval, the team recovered 61% of the eligible published studies for careful reuse.<\/p>\n Tracing the roots of intelligence<\/p>\n Studying great ape<\/a> cognition, how apes think and solve problems, helps connect observed behavior with mental processes more clearly.<\/p>\n Chimpanzees and bonobos are humans\u2019 closest living relatives, while gorillas and orangutans would require more observation because of sharper contrasts.<\/p>\n Comparing all four groups can reveal which skills run deep across apes and which ones grew differently in humans.<\/p>\n That boundary matters because shared abilities identify older inheritance, while differences show where human intelligence changed during evolution.<\/p>\n Watching minds change over time<\/p>\n Long records let researchers watch developmental<\/a> change, the way abilities alter with age, across the same individuals.<\/p>\n \u201cThis resource will also allow researchers to track long-term patterns and explore developmental questions that are impossible to answer with single studies,\u201d S\u00e1nchez-Amaro said.<\/p>\n Earlier work<\/a> found that some ape task performance stayed stable across time, so repeated testing can reveal durable individual differences.<\/p>\n Such patterns cannot prove human connections alone, but they sharpen comparisons that make claims about origins testable instead of vague.<\/p>\n High stakes of open data<\/p>\n Unfortunately, old research can disappear quietly when files sit on private drives, broken emails, or forgotten lab computers after staff move on.<\/p>\n One biology paper<\/a> found data access odds fell 17% each year after publication, which explains the urgency behind this archive.<\/p>\n The team followed FAIR principles<\/a>, rules that make records findable and reusable, so other scientists can inspect the files.<\/p>\n A public repository<\/a> keeps the material open-access, free for others to use and check, for years beyond one lab.<\/p>\n Boundaries of captive research<\/p>\n Still, the new record comes from captive apes at just one center, not from every ape population on Earth.<\/p>\n Voluntary testing also means each task reflects animals that chose to participate and did not provide a perfectly random sample.<\/p>\n Some older publications stayed outside the dataset because questions about files, authorship, or records could not be settled.<\/p>\n Those limits do not weaken the resource, but they keep claims honest and prevent careless overreading of results.<\/p>\n Textbook claims to raw evidence<\/p>\n Classrooms can use the same records to show students how animal behavior becomes real scientific evidence.<\/p>\n Instead of memorizing claims, learners can compare ages, species, tasks, and outcomes in real files from actual studies.<\/p>\n That experience fits comparative psychology<\/a>, science comparing behavior across species, because it links numbers to living animals.<\/p>\n Handled well, the dataset can teach care alongside curiosity, especially when students meet complex, imperfect evidence.<\/p>\n Expanding the dataset further<\/p>\n Future versions could add newer studies after 2021 and, later, observations of everyday social life among the same apes.<\/p>\n With more material, the Max Planck Institute for Evolutionary Anthropology can connect experiments to grooming, play, patience, and cooperation in richer, more social ways.<\/p>\n Large collaborative projects<\/a> have already shown that primate research gains strength when labs pool effort across different sites.<\/p>\n For the Max Planck Institute for Evolutionary Anthropology, the bigger challenge is turning access into careful questions instead of solely making bold claims about intelligence.<\/p>\n Shared story of thinking across species<\/p>\n A scattered archive has become a shared tool for tracing how ape minds develop, differ, and sometimes resemble our own.<\/p>\n Its strongest use will come from patient comparisons that respect limits while preserving rare animal histories for future researchers.<\/p>\n The study is published in the journal Scientific Data<\/a>.<\/p>\n \u2014\u2013<\/p>\n Like what you read?
