How dating has changed over the last 100 years
Ever since The Enlightenment, and possibly even before that, researchers have attempted to understand the chronology of the world around us, to figure out precisely when each stage in our geological, biological and cultural evolution took place. Even when the only science we had to go on was religious literature and the western world believed the world was created in BC 1 , scholars tried to figure out when each biblical event took place, to define a chronology from savagery to civilization, from creation to the first animal, then to the emergence of the first people.
The pre-enlightenment understanding of our geological and cultural history may now be proven wrong and subject to ridicule, but the principles of defining our place in time in the cosmos underpin many sciences. As technology advances, so do our methods, accuracy and tools for discovering what we want to learn about the past. All dating methods today can be grouped into one of two categories: absolute dating , and relative dating.
The former gives a numeric age for example, this artefact is years old ; the latter provides a date based on relationships to other elements for example, this geological layer formed before this other one.
And our DNA also holds clues about the timing of these key events in human evolution. When scientists say that modern humans emerged in Africa about , years ago and began their global spread about 60, years ago, how do they come up with those dates? Traditionally researchers built timelines of human prehistory based on fossils and artifacts, which can be directly dated with methods such as radiocarbon dating and Potassium-argon dating.
However, these methods require ancient remains to have certain elements or preservation conditions, and that is not always the case. Moreover, relevant fossils or artifacts have not been discovered for all milestones in human evolution. Analyzing DNA from present-day and ancient genomes provides a complementary approach for dating evolutionary events.
Because certain genetic changes occur at a steady rate per generation, they provide an estimate of the time elapsed. Molecular clocks are becoming more sophisticated, thanks to improved DNA sequencing, analytical tools and a better understanding of the biological processes behind genetic changes.

One of the most important dating tools used in archaeology may sometimes give misleading data, new study shows – and it could change whole historical timelines as a result. The discrepancy is due to significant fluctuations in the amount of carbon in the atmosphere, and it could force scientists to rethink how they use ancient organic remains to measure the passing of time.
A comparison of radiocarbon ages across the Northern Hemisphere suggests we might have been a little too hasty in assuming how the isotope – also known as radiocarbon – diffuses, potentially shaking up controversial conversations on the timing of events in history. By measuring the amount of carbon in the annual growth rings of trees grown in southern Jordan, researchers have found some dating calculations on events in the Middle East — or, more accurately, the Levant — could be out by nearly 20 years.
That may not seem like a huge deal, but in situations where a decade or two of discrepancy counts, radiocarbon dating could be misrepresenting important details. This carbon — which has an atomic mass of 14 — has a chance of losing that neutron to turn into a garden variety carbon isotope over a predictable amount of time. By comparing the two categories of carbon in organic remains, archaeologists can judge how recently the organism that left them last absorbed carbon out of its environment.
Over millennia the level of carbon in the atmosphere changes, meaning measurements need to be calibrated against a chart that takes the atmospheric concentration into account, such as INTCAL Levels do happen to spike on a local and seasonal basis with changes in the carbon cycle, but carbon is presumed to diffuse fast enough to ignore these tiny bumps. The tree rings were samples of Jordanian juniper that grew in the southern region of the Middle East between and CE. By counting the tree rings, the team were able to create a reasonably accurate timeline of annual changes in carbon uptake for those centuries.
Alarmingly, going by INTCAL13 alone, those same radiocarbon measurements would have provided dates that were older by an average of 19 years. The difference most likely comes down to changes in regional climates, such as warming conditions. Extrapolating the findings back to earlier periods, archaeologists attempting to pinpoint Iron Age or Biblical events down to a few years would no doubt have a serious need to question their calibrations.
