Did Hominids Who Lived 1.4 Million Years Ago Already Know Geometry?

<p>Spheroids, also known as stone balls, polyhedrons, or bolas, are amongst the oldest surviving lithic tool types, appearing as early as the Oldowan and continuing into the Middle Palaeolithic.</p> <p>However, their purpose and manufacturing process have long been debated. Previous studies were limited by small sample sizes and subjective classification schemes.</p> <p>To overcome these issues, the researchers introduced novel quantitative techniques, including edge angle measurement, centre of mass calculation, surface curvature analysis, and crucially, spherical harmonics analysis.</p> <p><a href="https://medium.com/illumination/did-hominids-who-lived-1-4-million-years-ago-already-know-geometry-8951ed2292d4"><strong>Read More</strong></a></p>
