The Museum of Natural History (The Field Museum) in Chicago was one of my favorite haunts until I left Chicago at the age of 17. There was a display called The Dawn of Man which featured a series of dioramas of perhaps 7 or 8 cases of life sized wax figures depicting mostly family groups, showing the evolution of man doing things in life like natural habitats. While it was no doubt inaccurate by todays standards (much of we know about physical anthropology has greatly changed since the early 1960s, as recent readings have surprised me a great deal from what I learned in college), it was fascinating and one of my favorite exhibits.
I revisited the place a couple of years ago, and it cost me a $100 membership to get me and 3 other guests in. It used to be free. It was disappointing that the display was gone and replaced by a comparatively informative display, but quite lackluster in comparison. When I inquired about the old display to an attendant, a younger woman who probably had never seen it, told me it was removed, not because it was inaccurate (according to her), but because it was racist, although I certainly didn't recall anything racist about it. I'm not sure she had her information correct. However, it WAS inaccurate by todays standards. Many of the prehistoric groups which were thought to be direct ancestors, are now considered branches that went extinct, but were not part of our direct evolutionary chain.
Replacing it with an up to date series of finely detailed wax figures is probably too expensive for the best of museums today. I can't imagine what the original display would cost in today's dollars. I'd guess in the millions of dollars.
None the less, thanks for the link to your site. I like this kind of stuff.
