Summary
How prescient were Science's editors and writers when they picked three areas to watch in 2016, as part of the 2015 Breakthrough of the Year package? On gravitational waves, they were spot on: The detection of the infinitesimal ripples in spacetime became Science's 2016 Breakthrough of the Year. The prediction that we may finally know where dogs came from was partially successful: A study indicated that they may have evolved from wolves once in Europe and once in Asia or the Near East. And the recommendation that we keep an eye on a French satellite, which will test whether falling bodies made of different materials accelerate at the same rate under Earth's gravity, is ongoing. The satellite is in the data-gathering phase.
