Two studies on bee evolution reveal surprises

... University found the bee embedded in amber from a mine in northern Myanmar (Burma). A report on this major fossil discovery, which the researchers say supports a new hypothesis in bee evolution, was published in the Oct. 27 issue of Science. Scientists have long believed that bees first appeared ...

From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea
