One of our most complete ancient ancestor’s fossils has been transported to the UK from South Africa in order to be scanned at the Diamond Light Source. Roland Pease investigates what these scans could reveal about the human story. Professor Corinne Le Quéré explains how she managed to look past the 7% reduction in human emissions caused by the pandemic in 2020 to reveal the impact of the Paris Climate agreements, and explains what more needs to be done. Roland speaks with anthropologist Dr. Rolf Quam, who has studied the inner ears of fossilised Neanderthal skulls to reveal they may have evolved the ability to hear the complex sounds of spoken language separately to our own species. Dr. Emma Hodcroft discusses the Brazilian P1 COVID 19 variant that is spreading around the world. (Image: Little Foot Skull. Copyright: Diamond Light Source Ltd)
