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.

Analysis of growth rings from pine trees in Sweden shows that the proliferation of atomic tests in the s and s led to an explosion in levels of atmospheric carbon Now, Jonas Frisen and colleagues at the Karolinska Institute in Stockholm have taken advantage of this spike in C14 to devise a method to date the birth of human cells. Because this test can be used retrospectively, unlike many of the current methods used to detect cell proliferation, and because it does not require the ingestion of a radioactive or chemical tracer, the method can be readily applied to both in vivo and postmortem samples of human tissues.

Because of its extremely long half-life over 5, years , carbon 14 content has typically been used to date only very old artifacts or fossils. The method has traditionally failed to resolve dates of samples that differ in age by less than a few hundred years—accurate enough perhaps to date the youngest and oldest parts of the most ancient redwood trees, but not to tell how many newborn cells might be present in the human brain.

But the almost tenfold increase in atmospheric C14 that peaked around the mids has been followed by a rapid decline since the nuclear test ban treaties and the cessation of high-yield, above-ground nuclear tests.

If wisdom comes with age, then brain cells are some of the wisest in the body: researchers have applied carbon dating to DNA to confirm that cells in the brain live longer than most others. This is a new application for the technique, which is traditionally used in archaeology and palaeoanthropology to pinpoint the age of fossils.

Carbon dating looks at the ratio of radioactive carbon, which is naturally present at low levels in the atmosphere and food, to normal carbon within an organism. While a creature lives, eats and breathes, its ratio of radioactive to normal carbon will equal that of its environment. But when it dies, this ratio will fall, as the carbon decays. Radioactive carbon decays slowly, such that a given amount of carbon halves every 6, years. So detecting the subtle change in the ratio of normal to naturally occurring radioactive carbon over just a few years is incredibly hard.
