Scientists have unveiled a 47-million-year-old fossilised skeleton of a monkey hailed as the missing link in human evolution. The search for a direct connection between humans and the rest of the animal kingdom has taken 200 years - but it was presented to the world today at a special news conference in New York. The discovery of the 95%-complete 'lemur monkey' - dubbed Ida - is described by experts as the "eighth wonder of the world". They say its impact on the world of palaeontology will be "somewhat like an asteroid falling down to Earth".
