Human anatomical modernity began approximately 200,000 years ago.
Human behavioral modernity began approximately 50,000 years ago.
The entirety of humanity’s known written record dates back approximately 5,000 years.
Consider what this means: Our brains have been as complex as they are now – we’ve possessed the same curiosity, drive, wanderlust, intelligence, and creativity – for at least 50,000 years. We’ve been exploring, experimenting, testing, learning, and figuring things out this whole time. It may be that we’ve been this curious and intelligent for the full 200,000 years of our existence.
If we take the 50,000 year mark – this means we only know, at most, 10% of everything we’ve done in that time. 90% of our own history is unknown to ourselves, except through some cave paintings and fossils.
If we take the 200,000 year mark – that percentage drops to 2.5%, leaving 97%-98% of our own history completely in the dark.
Humbling, ain’t it?
