Prehistoric teeth give up their secrets

The isotope values of food consumed are reflected in the individual's tissues. As bone is constantly being turned over by remodelling, analysing the stable isotope ratios of bone collagen can shine a light on the main dietary ...

Details of protein evolution investigated

Proteins govern the biology of the cell. Through random mutation the sequences of our proteins slowly change over time, usually without affecting function. But sometimes new functions will be invented in this process. Scientists ...
