A multidisciplinary team of researchers from the School of Anthropology and Museum Ethnography at the University of Oxford, the Max Planck Institute for Evolutionary Anthropology, the Jane Goodall Institute in Tanzania, the University of Algarve, and the University of Porto in Portugal, and the University of Leipzig has discovered that chimpanzees in Gombe Stream National Park, Tanzania, use a form of engineering in their tool-making. Specifically, they deliberately select plants that yield more flexible materials when crafting tools for termite fishing. The findings, published in the journal iScience, provide important insights into the technical skills involved in making perishable tools, an area that remains largely unknown in the study of human technological evolution.

Credit: Alejandra Pascual-Garrido Termites are a valuable food source for chimpanzees, offering energy, fat, vitamins, minerals, and protein. To access them, chimpanzees use thin probes to extract termites from their nests. Since the interior of termite mounds consists of narrow, winding tunnels, researchers proposed that flexible tools would be more effective than rigid ones for navigating these spaces and retrieving the insects. Testing chimpanzee tool materials for flexibility To test this, first author Alejandra Pascual-Garrido took a portable mechanical tester to Gombe and measured how much force it took to bend plant materials used by the apes compared to plant materials that were available but never used. Findings showed that plant species never used by chimpanzees were 175 percent more rigid than their preferred materials. Furthermore, even among plants growing near termite mounds, those that showed obvious signs of regular use by the apes produced more flexible tools than nearby plants that showed no signs of use.

Credit: Alejandra Pascual-Garrido “This is the first comprehensive evidence that wild chimpanzees select tool materials for termite fishing based on specific mechanical properties,” says Alejandra Pascual-Garrido, who has been studying the raw materials used in chimpanzee tools in Gombe for more than a decade. Notably, certain plant species, such as Grewia spp., also constitute tool material for termite fishing chimpanzee communities living up to 5,000 kilometers away from Gombe, implying that the mechanics of these plant materials could be a foundation for such ubiquitous preferences and that rudimentary engineering may be deeply rooted in chimpanzee tool-making culture. Chimpanzees show an intuitive understanding of material function Wild chimpanzees may therefore possess a kind of “folk physics” – an intuitive comprehension of material properties that helps them choose the best tools for the job. Their natural engineering ability is not just about using any stick or plant that is available; chimpanzees specifically select materials with mechanical properties that can make their foraging tools more effective. Dr Alejandra Pascual-Garrido, Research Affiliate at the School of Anthropology and Museum Ethnography, University of Oxford, said: “This novel approach, which combines biomechanics with animal behavior, helps us better understand the cognitive processes behind chimpanzee tool construction and how they evaluate and select materials based on functional properties.” A Gombe chimpanzee using a termite fishing tool to fish termites. Credit: Alejandra Pascual-Garrido The findings raise important questions about how this knowledge is learned, maintained, and transmitted across generations, for example, by young chimpanzees observing and using their mothers’ tools, and whether similar mechanical principles determine chimpanzees’ selection of materials for making other foraging tools, such as those used for eating ants or harvesting honey. Linking chimpanzee tool use to human evolution “This finding has important implications for understanding how humans might have evolved their remarkable tool-using abilities,” explains Adam van Casteren, Department of Human Origins, Max Planck Institute for Evolutionary Anthropology, a specialist in biomechanics and evolutionary biology. “While perishable materials like wood rarely survive in the archaeological record, the mechanical principles behind effective tool construction and use remain constant across species and time.” By studying how chimpanzees select materials based on specific structural and/or mechanical properties, we can better understand the physical constraints and requirements that would have applied to early human tool use. Using such a comparative functional framework provides new insights into aspects of early technology that are not preserved in the archaeological record.

New research suggests that the orca pods in the northern Pacific, near Japan and Russia, have distinct cultures, dialects, and traditions due to their ice age ancestry, with some pods staying in their refugiums from the ice age rather than migrating. The researchers argue for the classification of orcas into several species or subspecies due to their vast differences in diet and behavior, emphasizing the importance of understanding different orca ecotypes for ecosystem balance and fishing practices. Orcas in North Pacific. Credit: SDU/Olga Filatova Exploring Orca Colonization in the North Pacific The northern Pacific near Japan and Russia is home to several different groups of orcas yet they never interact, hunt different prey, communicate in distinct dialects, and avoid mating with one another. How can this be when they live so close to each other and belong to the same species? Whale expert Olga Filatova from the University of Southern Denmark has dedicated her research to unraveling the mysteries of orca colonization in the northern Pacific. During her tenure at a Moscow University, she led multiple expeditions to study these enigmatic creatures. Currently, she is affiliated with the Marine Biological Research Center at the University of Southern Denmark. Now, some of her latest results have been published. In a recent paper, she and colleagues explore the complex interaction between orca culture and the post-glacial history of their colonization of the North Pacific, showing that the orca pods currently living near Nemuro Strait in northern Japan are descendants of orcas that settled there during the last ice age, around 20,000 years ago. The location was chosen as a refugium by distant ancestors, and their descendants have lived there ever since. “Orcas are conservative and tradition-bound creatures who do not move or change their traditions unless there is a very good reason for it. We see that in this population,” says Olga Filatova. This is the second time she finds an orca refugium from the ice age. The first one is near the Aleutian Islands, some 2500 km away. The pods there are just as conservative and tradition-bound as their Japanese conspecifics and are also descendants of ice age ancestors who found refuge in ice-free waters. Orcas in North Pacific. Credit: SDU/Olga Filatova “When the ice began to retreat again, and orcas and other whales could swim to new ice-free areas, some of them did not follow. They stayed in their refugiums, and they are still living there,” says Olga Filatova. Genetic and Vocal Analysis Reveal Orca Lineage The studies are based on genetic analyses (the researchers took skin biopsies of the animals) and analyses of sounds made by the animals (recorded with underwater microphones). “Orcas in the Nemuro Strait had unusually high genetic diversity, which is typical for glacial refugiums, and their vocal repertoire is very different from the dialects of orcas living to the north off the coast of Kamchatka. Kamchatkan orcas are most likely the descendants of the few pods that migrated west from the central Aleutian refugium, that’s why they are so different”, says Olga Filatova. Orcas’ vocalizations are highly diverse, and no two pods make the same sounds. Therefore, these sounds can be used to identify individuals’ affiliations with families and pods. Orcas are not genetically programmed to produce sound like, for example, a cat is. A cat that grows up among other animals and has never heard another cat will still meow when opening its mouth. In contrast, orcas learn to communicate from their mother or other older family members. Each pod has its own dialect, not spoken by others. “When we combine this with genetic analyses, we get a strong idea of how different orca communities relate to each other,” says Olga Filatova. Orca Migration and Climate Change So far, two ice age refugiums have been discovered, providing us with insight into how orcas may handle current and future climate changes: they will likely move northward as the ice melts, and this colonization may happen in small, individual families or pods rather than in large waves. Orcas in North Pacific. Credit: SDU/Olga Filatova The discovery of the two ice age refugiums not only contributes to knowledge about how orcas survived during the ice age, but it also paints a picture of orcas as very different animals that may not fit neatly into one species. “Many believe that orcas should be divided into several species. I agree – at least into subspecies because they are so different that it doesn’t make sense to talk about one species when discussing their place in the food chain or when allocating quotas to fishermen,” says Olga Filatova. Dietary Preferences and Their Impact on Ecosystems Some orcas eat fish, some only herring, some only mackerel, some only a specific type of salmon. Others only eat marine mammals such as seals, porpoises, and dolphins. Some take a little of everything, and still others live so far out in the open sea that we fundamentally know very little about them. Whether a pod eats fish – and which fish – has a significant impact on the fishing that takes place in their habitat. When a country calculates fishing quotas, it must take into account how many fish are naturally hunted by predators, and since an orca can consume 50-100 kg (110-220 lb) of fish in a day, it greatly affects the quota calculation. If pods eat marine mammals and do not touch fish, this matters if they are to be captured and sold to marine parks, where it is difficult to feed them marine mammals. While marine parks’ popularity is declining worldwide, there is still a large market for orcas in Chinese marine parks. Since there is only one scientifically recognized species of orcas, researchers have resorted to a different form of classification to distinguish between different types of orcas and categorize them into so-called ecotypes. In the northern Pacific, three ecotypes have been defined so far, and in the southern hemisphere, four or five have been described. There are probably more – perhaps up to 20 different ecotypes, according to Olga Filatova. “We need to know the different ecotypes. Orcas are at the top of the food chain, and it affects the entire ecosystem around them what they eat, and where they do it,” says Olga Filatova. In the Danish waters, Skagerrak and Kattegat, close to SDUs Marine Biological Research Center, orcas are occasionally seen. Yet, no one knows if they eat fish or marine mammals – and therefore, also, how they affect the food chain and fishing. “I look forward to learning more about them. Maybe they turn out to belong to a new ecotype,” says Olga Filatova. Pods, families, and clans: Orcas live in families, led by matriarchs. Families gather in close-knit groups, called pods. Clans consist of pods with similar vocal dialects. Ecotypes of orcas: Ecotypes have different dialects, and different habitats, and do not mate with each other. Researchers believe that there may be up to 20 different ecotypes. Known ecotypes in the Northern Pacific: Residents: Close-knit families and pods that stay in the same areas along the coasts. Feed on fish. Transients: Smaller, less cohesive pods that feed on marine mammals. Habitat from Russia to California. Offshore: Live far out in the open sea in groups of 20-200 individuals. Poorly studied. Known ecotypes in the southern Antarctic: Type A: Travel in open waters and seems to feed mostly on minke whales. Type B: Smaller than Type A. Seems to feed mostly on seals. Type C: The smallest. Live in larger groups than the others. Seems to feed mostly on fish. Type D: Range between the 40th and 60th southern latitudes. These are poorly studied. Possible new ecotypes: Groups that feed on fish in the North Atlantic. Groups that feed on marine mammals in the North Atlantic. Groups that feed on penguins and sea lions on the coast of South America. Groups around Gibraltar, feeding on tuna. Groups in the tropics around Hawaii and Gulf of Mexico. Groups around New Zealand, primarily feeding on rays and sharks. Reference: “Genetic and cultural evidence suggests a refugium for killer whales off Japan during the Last Glacial Maximum” by Olga A.

Scientists have discovered how the protein DDM1 aids in the methylation process that silences “jumping genes” in plants. Their findings also reveal how DDM1’s interaction with specific histones ensures the preservation of epigenetic controls across generations, which could have implications for agriculture and human genetics. Scientists identified how DDM1 enables DNA methylation by displacing histones, preserving epigenetic memory across generations in plants—a process that may also have implications for human genetics. When organisms pass their genes on to future generations, they include more than the code spelled out in DNA. Some also pass along chemical markers that instruct cells how to use that code. The passage of these markers to future generations is known as epigenetic inheritance. It’s particularly common in plants. So, significant findings here may have implications for agriculture, food supplies, and the environment. Cold Spring Harbor Laboratory (CSHL) Professors and HHMI Investigators Rob Martienssen and Leemor Joshua-Tor have been researching how plants pass along the markers that keep transposons inactive. Transposons are also known as jumping genes. When switched on, they can move around and disrupt other genes. To silence them and protect the genome, cells add regulatory marks to specific DNA sites. This process is called methylation. Arabidopsis thaliana is a plant species widely used to make fundamental biological discoveries. With the help of this versatile test subject, CSHL scientists have now dug up the secrets of a process that helps control inheritance. Credit: Martienssen lab/Cold Spring Harbor Laboratory Understanding the Function of DDM1 Martienssen and Joshua-Tor have now shown how protein DDM1 makes way for the enzyme that places these marks on new DNA strands. Plant cells need DDM1 because their DNA is tightly packaged. To keep their genomes compact and orderly, cells wrap their DNA around packing proteins called histones. “But that blocks access to the DNA for all sorts of important enzymes,” Martienssen explains. Before methylation can occur, “you have to remove or slide the histones out of the way.” Martienssen and former CSHL colleague Eric Richards first discovered DDM1 30 years ago. Since then, researchers have learned it slides DNA along its packing proteins to expose sites needing methylation. Martienssen likens the movement to a yo-yo gliding along a string. The histones “can move up and down the DNA, exposing parts of the DNA at a time, but never falling off,” he explains. This cartoon model illustrates, for the first time, where and how the DDM1 protein (purple) grips onto DNA (beige) during cell division. Credit: Joshua-Tor lab/Cryo-EM Facility/Cold Spring Harbor Laboratory Through genetic and biochemical experiments, Martienssen pinpointed the exact histones DDM1 displaces. Joshua-Tor used cryo-electron microscopy to capture detailed images of the enzyme interacting with DNA and associated packing proteins. They were able to see how DDM1 grabs onto particular histones to remodel packaged DNA. “An unexpected bond that ties DDM1 together turned out to correspond to the first mutation found all those years ago,” Joshua-Tor says. Histone Memory and Epigenetic Inheritance The experiments also revealed how DDM1’s affinity for certain histones preserves epigenetic controls across generations. The team showed that a histone found only in pollen is resistant to DDM1 and acts as a placeholder during cell division. “It remembers where the histone was during plant development and retains that memory into the next generation,” Martienssen says. Plants may not be alone here. Humans also depend on DDM1-like proteins to maintain DNA methylation. The new discovery may help explain how those proteins keep our genomes functional and intact.
