They roamed open grasslands and wooded areas in Eastern Africa before going extinct around 1.2 million years ago. Recent scientific studies have shattered long-held beliefs about those close relatives of the human species. Nutcracker Man (Paranthropus boisei) has no direct connection to human beings. They did not belong to the genus Homo. Instead, Paranthropus boisei is an evolutionary side branch and an extinct cousin of human ancestors who lived in East Africa alongside early Homo species. The main characteristics of the Nutcracker Man were walking upright on two legs, massive jaws with huge flat molar teeth and a small brain rather than a large one.

Paranthropus boisei appeared approximately 2.3 million years ago and survived on the Earth until about 1.2 million years ago. Their fossils have been found in various parts of East Africa, including Tanzania, Kenya and Ethiopia. Scientists nicknamed the extinct hominin Nutcracker Man for its large teeth and powerful jaw muscles. However, tooth chemistry shows that they used to consume mostly grasses and sedges rather than hard nuts.

The first famous fossil skull of Nutcracker Man, designated OH 5, was discovered by paleoanthropologist Mary Leakey on July 17, 1959 at Olduvai Gorge in Tanzania. Older estimates based on rare skeletal bone fragments from the Smithsonian National Museum of Natural History suggested that male Paranthropus boisei averaged about 4.2-4.5ft tall and weighed around 49kg. However, a recent study published in the Proceedings of the National Academy of Sciences has revealed that they grew up to 6ft tall and weighed around 75kg, rivalling the size of Homo erectus.

Analysis of some 1.43-million-year-old fossilised footprints has revealed this. These footprints have been found at site GaJi10 near Kenya’s Lake Turkana. Based on an analysis of these, researchers have claimed that the appearance of Nutcracker Man bore a strong resemblance to that of the human species. According to researchers, Nutcracker Man not only reached a height of up to 6ft, but also possessed human-like bipedal walking mechanics and precision hand grips.

Kevin Hatala, of Chatham University and an Associated Researcher of the Department of Human Origins at the Max Planck Institute for Evolutionary Anthropology in Leipzig who led the research team, estimates that those footprints are approximately 1.4 million years old. In fact, various human species had already emerged by that time, and Nutcracker Man and the extinct Homo erectus lived in that particular area at the same time.

Interestingly, those footprints near Lake Turkana were discovered a long time ago as the 1978 discovery was actually made by US paleoecologist Kay Behrensmeyer, who found fossilised tracks along the lake. Footprints of another 14 hominins were discovered in 2016 and 2023.

Recent research has revealed that those footprints did not belong solely to Nutcracker Man; some of them belonged to Homo erectus, as well. According to Kevin, this estimate of their stature is larger than previous ones for these hominins, who left these prints some 1.43 million years ago, when Homo erectus also lived in the region. He stressed: “They may have lived in large groups, where males competed for mates, but also tolerated each other at times for safety in a dangerous environment.” Paleontologists believe that further research is required on this matter.

Koushik Das (born on May 16, 1976 in Kolkata) is a career journalist. Based in the Indian capital of New Delhi, Koushik writes mainly about foreign policies and current geopolitical issues, and rarely about other topics. His own political ideas are highly influenced by Antonio Gramsci, Louis Althusser, Michel Foucault, Michael Oakeshott and others. English philosopher and political theorist Oakeshott (Dec 11, 1901-Dec 19, 1990) says that “in political activity, men sail a boundless and bottomless sea. There is neither harbour for shelter nor floor for anchorage, neither starting-place, nor appointed destination. But we have to keep afloat”. (Rationalism in Politics, 1962) As a student of Political Science, Koushik loves to share his views on issues, which have great impacts on his thought process (and also on India, South Asia and of course on the global community), with his readers through his website – Boundless Ocean of Politics. By doing so, he tries to keep himself afloat. You will find some of his articles in https://inserbia.info/today/ (https://inserbia.info/today/author/kou_das13_i/), as he has been trying to assess the global geopolitics since 2003.
