Recently, following the lead of World Magazine’s Marvin Olasky who originally reported it, I commented on the difference in approach to covering evolution taken by two distinguished museums: the Smithsonian’s National Museum of Natural History and the American Museum of Natural History (AMNH) in New York City. Basically, the Smithsonian gives a smooth, conflict-free presentation aimed at indoctrinating young people, while the AMNH at least admits to some difficulties in the evidence.
But there’s more. An email correspondent points out that the different methods stem from the specific decades when the halls were respectively updated and redesigned:

The AMNH’s infusion of evolutionary theory is subtle enough in some places that Marvin Olansky didn’t notice it: look at the floor in the hall of dinosaurs. There are brass tiles going every which-way, but they are part of an elaborate cladogram of relationships among the dinosaurians. You’re literally walking through evolution.
Part of the differences [between the museums], though, reflects the timing of these updates: the Smithsonian’s began with the opening of the new Hall of Mammals in 2005 or so, followed by Oceans, then Human Origins, and now Dinosaurs is under construction. It’s been a very aggressive pace over the past decade, and coincides with some major cultural challenges to evolution from Kansas in 1999 through Dover to today. They are in a fight, and they know it.
The revamped hall of dinosaurs at the AMNH, however, was designed during the relatively quiescent mid-1990s, as far as these issues go, and before the currently nasty forms of discourse. It was considered strong propaganda for its time, but its time was rather different than the new Smithsonian exhibits. ID wasn’t yet strongly on the radar: though Phillip Johnson and Michael Behe’s books had made quite a splash, the bigger ID push hadn’t started yet.

That’s very insightful: “They are in a fight, and they know it.” He says, in other words, that putting evidence for or against Darwinian evolution to one side, the halls of these two great natural history museums bear witness to the impact of the ID debate on the public presentation of science. Even when unacknowledged, intelligent design is too significant to disregard.
