A new species of gibbon is found in a 2,200-year-old tomb
Royal burials are just not what they used to be. While still a child, Qin Shihuang, who founded the Qin dynasty and unified China in 221BC, ordered a mausoleum built for himself that would measure 6.3km across at its widest point and include over 8,000 terracotta figures. His grandmother, Lady Xia, was also buried with several companions. When her tomb near Xi’an was excavated in 2004, archaeologists found in it the remains of a leopard, a lynx, a crane and a gibbon—a type of small ape. For The Economist's science and technology desk.
