On Friday, the American Museum of Natural History released the above video, which maps the growth and migration of the human population from our origin as a species up to the present day.

Modern humans emerged around the horn of Africa around 200,000 years ago. The earliest example of Homo sapiens is Omo-1, a hunter whose 195,000 year old remains were found in Ethiopia’s Omo Valley in 1967. Modern humans began migrating out of Africa about 100,000 years ago, using land bridges to spread across the Middle East, Europe and Asia.
It took Homo sapiens 200,000 years to reach the first billion people, but for the majority of this time the human population was pretty small—likely less than one million people. There were a few near extinction events, such as the massive volcanic eruption in Sumatra about 70,000 years ago which may have left as few as 2000 humans alive.
With the advent of agriculture roughly 12,000 years ago, the human population began to balloon from an estimated five million in 8,000 BC to roughly 170 million people by AD 1. Over the next 2,000 years, things start to get pretty wild. The 1 billionth Homo sapiens was estimated to have been born around 1804 and person number 2,000,000,000 wouldn’t be born until 1927. That means within the last 90 years, we’ve managed to add an additional 5 billion people to the globe.
