Joe Rogan Experience #2547 - Daniel Everett · Aired Aug 27, 2026
Claim summary · not a verbatim quotation
Homo erectus had brain sizes between 950 and 1,000 cubic centimeters.
The finding
What the evidence shows
Homo erectus brain sizes actually varied a lot more than that, from about 546 cubic centimeters in some early specimens up to 1,251 in the latest surviving populations. Averages differ heavily by region and time period too, with East Asian Homo erectus averaging close to 1,000 cubic centimeters, so treating 950 to 1,000 as the general range for the whole species understates how much it actually varied.
