Histomaps of religion and evolution

You've seen John B. Spark's Histomap of world empires, but he also made versions charting religions, "from primitive cults to modern philosophies," and the evolutionary tree. These are very hard to find, now, but pop up on eBay now and again: the lone current offering there, of the religion map, is already at $155, with thirty bids and more than 5 days left on the clock. A photo of the top half is in the auction gallery.

Embedded below, however, is a great big 5MB JPG of the evolutionary map, spotted by Slate's Rebecca Onion at Samphan Sittiwantana's Pinterest page.
