SUDBURY, Ont. — The mountain-sized meteorite that struck Sudbury nearly two billion years ago — already known to have made the northern Ontario city a global mining mecca — may have also triggered changes in Earth's ocean chemistry that allowed complex life to begin evolving on the planet, two U.S. government scientists have theorized.
Scientists John Slack and Bill Cannon of the U.S. Geological Survey say the colossal Canadian impact 1.85 billion years ago may have generated an unprecedented "mega-tsunami" that stirred oxygen into the deep ocean and jump-started the evolution of organisms beyond their bacterial beginnings.

Life may have begun in Sudbury, but from your video it looks like evolution in Sudbury has progressed very slowly :)
