They've covered the popular "Lion Attacking a Dromedary” diorama at the Carnegie Museum of Natural History in Pittsburgh — do you see why?

Here's the article in USA Today: 

The museum’s interim director says the scene... has disturbed some because it depicts violence against a man described as an Arab courier.

Wait! Is the human figure a taxidermied human being?! 

The director, Stephen Tonsor, also says recent X-rays showed that the 1860s-era taxidermy was performed with real human bones from an unknown person. Tonsor says the museum’s ethics policy requires that any human remains respect the person’s cultural traditions and be done with permission “of the people whose remains are displayed.”

I replaced the dramatically lit photo from the newspaper with the Creative Commons image at Wikipedia (by Mike Steele), which shows the human figure much more clearly. Let's read more detail at Wikipedia:

The diorama [by French taxidermist Édouard Verreaux] was created for the Paris Exposition of 1867 and subsequently shown at the American Museum of Natural History, Centennial Exposition, and the Carnegie Museum of Natural History. As part of a 2017 restoration, the museum found human remains in the diorama. In 2020, the diorama was removed from view in response to the Black Lives Matter movement.... In the creation of the work, Verreaux used bones and skins to form the stuffed dromedary and two stuffed lions. The human figure was made mostly of plaster.... 

After the death of Verreaux in 1867, Lion Attacking a Dromedary was sold to the American Museum of Natural History and shown at the 1876 Centennial Exposition. In 1898, it was sold to the Carnegie Museum of Natural History for $50 (equivalent to $1,537 in 2019). The work was considered to be "too theatrical" to be displayed at the American Museum of Natural History.

So... it's bad "natural history," more of a 19th century curiosity. The American Museum of Natural History actually considered destroying it in 1898 because it was considered "too emotional and distracting for educational purposes." The argument on the other side had to do with its power to draw people into the museum. It's entertainment... watching this imaginary man terrified by a lion. As the years wore on, the criticism grew. It was disparaged as "orientalist."

The human remains problem emerged much more recently, giving a separate reason for removing it (at least from a place of honor):

As part of [a 2016] restoration, the museum conducted tests on the animals using X-rays and DNA analysis techniques of the taxidermied animals to determine if they were genuine. Verreaux was known to fake records to inflate the selling price of his dioramas. The human figure was determined to be mostly synthetic, but, to the surprise of the museum, the head contained a human skull. Previously, it was thought that the human figure was only made of plaster. It is unknown who the skull belongs to or where Verreaux collected the skull from. In January 2017, the diorama went back on display in the foyer of the museum, previously it was in the hall of North African mammals, and the name was changed from Arab Courier Attacked by Lions to Lion Attacking a Dromedary.... 

In July 2020, the Carnegie Museum of Natural History removed Lion Attacking a Dromedary from view citing the Black Lives Matter movement and the lack of accuracy. The museum is considering moving the diorama to a part of the museum where it can be avoided.... The diorama is inaccurate both scientifically and anthropologically and is considered to be a work of fiction. 

Maybe relocate it to a museum dedicated to human culture and present it as something that illustrates what 19th century French people were like.
