But how did we come to have smooth, spoken language?Scientists have turned to our relatives, non-human primates, for answers. In the hunt for what makes us unique, researchers have some ideas. One distinction they have long highlighted is the position of humans' voice box. Humans have a low larynx, while other primates have a high larynx. A..>> view originalHow old is the moon? Older than we thought, say scientists.
January 12, 2017 —How old is the moon?Surprisingly, that question has proven to be a difficult one to answer. The hypothesized initial impact that created Earth's satellite must have occurred billions of years ago, but estimates as to precisely when have varied by hundreds of millions of years.Now, a team of researchers think they can nail down a more precise age for the moon, based on a new analysis of minerals present in moon rocks gathered by Apollo astronauts more than four decades ago.
