Read Unlocking the Past Storyline:
In Unlocking the Past, Martin Jones, a leading expert at the forefront of bioarchaeology—the discipline that gave Michael Crichton the premise for Jurassic Park—explains how this pioneering science is rewriting human history and unlocking stories of the past that could never have been told before. For the first time, the building blocks of ancient life—DNA, proteins, and fats that have long been trapped in fossils and earth and rock—have become widely accessible to science. Working at the cutting edge of genetic and other molecular technologies, researchers have been probing the remains of these ancient biomolecules in human skeletons, sediments and fossilized plants, dinosaur bones, and insects trapped in amber. Their amazing discoveries have influenced the archaeological debate at almost every level and continue to reshape our understanding of the past.Devising a molecular clock from a certain area of DNA, scientists were able to...Pages of Unlocking the Past :
