Until recently, life on Earth was said to have begun 3.5 billion years ago, a date originally based on curvaceous, worm-like strings of microfossils â tiny remains of bacteria, protists, fungi, animals, and plants five-thousandths of a millimetre in length, found in the ancient rocks of Western Australia's Marble Bar.
Every time we pass another population milestone â at the moment, weâre tallying a whole-Earth total of 7 billion â the question arises: How many people have ever lived on the planet? The Population Reference Bureau, or PRB, has an answer for that. (Make your guess now; the answer will appear lower down.) But itâs heavily qualified, and thereâs a story behind it. The story starts sometime in the 1970s, when a notion came into common conversation that the population was growing so fast that 75 percent of the people who had ever lived on Earth were currently alive.
