Darwin’s birthday present

The appearance this week of Ida, our lemur-like, 47-million-year-old ancestor, is a bright spot in an otherwise troubled world. Ida is being hailed as the original embryonic primate from which today’s great array of monkeys, apes and ultimately human beings sprang. Ida was six months old when she died and has been perfectly preserved in the Messel pit near Darmstadt in Germany, her baby teeth intact, her last vegetarian meal still in her stomach.
