Scientists spot puzzling, unusually perfect holes on the ocean floor

At over 8,000 feet beneath the Atlantic Ocean, scientists spotted an unusual line of almost perfectly-spaced holes. The little pits, near the Mid-Atlantic Ridge, have baffled researchers. “The origin of the holes has scientists stumped,” tweeted the U.S. National Oceanic and Atmospheric Administration.  The agency explored the sea floor with a remote-operated vehicle, or ROV.The expertly-aligned holes make it appear that they could be from human activity. But a key scientist isn’t nearly convinced.
