This method is based on the fact that when a material is heated or exposed to sunlight, electrons are released and some of them are trapped inside the item.Once you heat this item again using high temperatures, the trapped electrons become excited and recombine with the item’s material.In 1823, John Haywood mentioned the impressive mound: “of a conical form, 75 feet high.In the interior of this mound, human bones were found, of uncommonly large size.” At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings.Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events.Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable.This process frees energy in the form of light, which can be measured.
The isotope of Potassium-40, which has a half-life of 1.25 Billion years, can be used for such long measurements.Read More A team of archaeologists in Egypt have unearthed four ancient child graves at Gebel el-Silsila, the site of a former Egyptian quarry that dates back 3,500 years. Like the anxious men who began excavations at Pompeii in the 18th century and discovered more about the ancient Italians than they had bargained for – such as phallic-shaped lamps – historians of sex are regularly confronted with case studies from the past that challenge their own ethics.The ancestors of modern humans (Homo sapiens) were not the grunting, drooling, primitive, brutes that you see depicted in cartoons or movies.Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us.
