The ability to precisely date, or identify the age of an object, can teach us when Earth formed, help reveal past climates and tell us how early humans lived. So how do scientists do it? Radiocarbon dating is the most common method by far, according to experts. This method involves measuring quantities of carbon, a radioactive carbon isotope — or version of an atom with a different number of neutrons.

While true, fossils are buried with plenty of clues that allow us to reconstruct their history. In , in Ethiopia's Afar region, our research team discovered a rare fossil jawbone belonging to our genus, Homo. To solve the mystery of when this human ancestor lived on Earth, we looked to nearby volcanic ash layers for answers. Working in this part of Ethiopia is quite the adventure. It is a region where 90 degrees Fahrenheit seems cool, dust is a given, water is not, and a normal daily commute includes racing ostriches and braking for camels as we forge paths through the desert.
