Tiny Wee Creatures From Very Very Long Ago

Fossils discovered in the Scottish Highlands, could be the oldest multicellular animal ever found. The organism, named Bicellum brasieri, lived 1,000,000,000 years ago, and has 2 different types of cells. It was only 3 hundredths of a millimeter across, and looked like a round blob, but it could bridge the evolutionary gap between single-celled and multi-celled creatures.
