Just a few quotes that support the thesis of the article;

“Fortune brings in some boats that are not steered.”~ William Shakespeare

“Those who have succeeded at anything and don’t mention luck are kidding themselves.”~ Larry King

“In a manner which matches the fortuity, if not the consequence, of Archimedes’ bath and Newton’s apple, the [3.6 million year old] fossil footprints were eventually noticed one evening in September 1976 by the paleontologist Andrew Hill, who fell while avoiding a ball of elephant dung hurled at him by the ecologist David Western.”~ John Western, “Missing Links: The Hunt for Earliest Man”.
