Scientists unveil fossil of 47 million-year-old primate, Darwinius masillae
Feast your eyes on what a group of scientists call the Holy Grail of human evolution.
A team of researchers Tuesday unveiled an almost perfectly intact fossil of a 47 million-year-old primate they say represents the long-sought missing link between humans and apes.
Officially known as Darwinius masillae, the fossil of the lemur-like creature dubbed Ida shows it had opposable thumbs like humans and fingernails instead of claws.
Scientists say the cat-sized animal's hind legs offer evidence of evolutionary changes that led to primates standing upright - a breakthrough that could finally confirm
Charles Darwin's theory of evolution.
"This specimen is like finding the Lost Ark for archeologists," lead scientist
Jorn Hurum said at a ceremony at the American Museum of Natural History.
