"Following the Christie's link, we find:
Provenance
Acquired by the current owner's father in Egypt in the 1920s.

Translation:
Provenance
Immorally (if not illegally) acquired by the current owner's father in Egypt in the 1920s from grave robbers."

Exactly. I wish boingboing would stop featuring looted artifacts. The antiquities trade is not a wonderful thing.

I am happy to see that most people have as much use for evolutionary psychology as I do. It's sad that there is so much good work going on out there, and these guys write a popular science book that is going to get a lot of press and which most people will not question the veracity of. Very frustrating.
