The genus Simia is still in use, though, most notably for the Barbary macaque. It wasn't until 1929 that the International Commission on Zoological Nomenclature recommended no longer using the taxon Simia because it is "paraphyletic" (meaning: a confusing, catch-all term). In the middle of the 18th century, then, there was no scientific distinction at the superfamily level between apes and monkeys as there is today. (Arguably, it still is today.) The original scientific classification system, created by Carl Linnaeus, includes four genera under the order Primates: Homo (humans), Simia (monkeys and apes), Lemur (lemurs and colugos) and Vespertilio (bats).

We now want to investigate the factors triggering these surprisingly aggressive interactions,” said Tobias Deschner, a primatologist at the Max Planck Institute for Evolutionary Anthropology, in a statement.Page from Linnaeus' Systema Naturae (c. “Our observations provide the first evidence that the presence of chimpanzees can have a lethal impact on gorillas. Both chimpanzees and gorillas can be territorial, but violent fights happen almost exclusively within their own species. The group said that more research is needed to determine what is provoking the change of behavior. Our colleagues from Congo even witnessed playful interactions between the two great ape species.” “We have regularly observed both species interacting peacefully in foraging trees. “Interactions between chimpanzees and gorillas have so far been considered as relatively relaxed,” said Simone Pika, a cognitive biologist at Osnabrück University, in a statement. The adult gorillas were able to escape from the group of chimps, but an infant separated from its mother did not survive. While both species can be territorial and violent, fights happen almost exclusively within their own species. The researchers, who are from the Osnabrück University and the Max Planck Institute for Evolutionary Anthropology in Germany, said the encounters were wildly different from how the two species typically interact with each other. LCPīut instead of the slain gorilla being left alone, the “infant in the second encounter was almost entirely consumed by one adult chimpanzee female,” the study said. In December 2019, more than two dozen chimps went after five gorillas. Researchers said a similar attack occurred in February 2019 that also left an infant gorilla dead. While the adult gorillas were able to escape, the infant separated from its mother didn’t survive, the study said. “But then, we heard chest beats, a display characteristic for gorillas, and realized that the chimpanzees had encountered a group of five gorillas.” Southern, the study’s lead author, in a statement. “At first, we only noticed screams of chimpanzees and thought we were observing a typical encounter between individuals of neighboring chimpanzee communities,” said Lara M. In the first attack in December 2019, more than two dozen chimps went after five gorillas. The lethal encounters between the two species occurred as they were being observed at Loango National Park in Gabon, according to a study Monday in the journal Nature. ‘Filthy’ zoo refuses to release ‘world’s saddest gorilla’ for less than $780KĬhimpanzees have been seen killing gorillas in unprovoked attacks for the first time, scientists said.
