This time next year, our understanding of our origins will have been transformed.
Molecules in the fossils of our ancestors are increasingly opening a new window on the evolution of the first hominids. Recently, the limits of this approach have been pushed further, with analysis of dental enamel proteins from a 2-million-year-old fossil of the extinct giant ape Gigantopithecus.
