Histomaps of 4,000 years of human civilization and 10,000 years of evolution

From BoingBoing:
John B. Sparks' 1931 Histomap charted 4,000 years of human civilization with beautiful, reductive clarity. Here's John Brownlee, at Fast Company: "From a modern perspective, Sparks’ Histomap will raise a few eyebrows. For one, it subscribes to an outdated (but, at the time, quite in vogue) idea about how different cultures throughout history could be grouped into various 'peoples.' The chart also underestimates or omits certain cultures that historians at the time didn’t truly appreciate the importance of... It seems hard to find in print form at a reasonable price. I've embedded an enormous 2MB image."

Also from BoingBoing:
Sparks also made a version charting the evolutionary tree. "Embedded below is a great big 5MB JPG of the evolutionary map, spotted by Slate's Rebecca Onion at Samphan Sittiwantana's Pinterest page."
