First, a quick note about what we mean when we are talking about modern humans:
1. About 7% percent of all humans who have ever lived are alive today.
2. The current population of Los Angeles County is likely double that of the world population at 8000 B.C.
3. Modern humans have been around for at least 50,000 years. In that period of time, all of recorded human history as we know it could have repeated itself nearly 10 times.
4. Throughout much of the early history of Homo sapiens, humans co-existed with other species of humans.
5. Humans even had sex with Neanderthals and Denisovans from time to time.
6. Modern humans and Neanderthals co-existed for at least 10,000 years. To put that in perspective, that is the same amount of time from 8000 B.C. to the present.
7. Before Homo sapiens, many other Homo species migrated from Africa and set up roots around the world before going extinct.
8. Neanderthals had their own thing going on for around 200,000 years before they disappeared — around four times the current reign of modern humans.
9. And that's nothing compared to Homo erectus, whose reign spanned 1.5 million years — nearly 300 times the length of recorded human history.
10. Here's another crazy thing: All the languages on Earth may have come from a single African language.
11. And finally: There's a good chance that all humans alive today descended from a population of humans as small as 2,000 people.
We humans are pretty resilient creatures!
