Natural selection
…The only thing the [Harvard] Agassiz Museum is missing is science. The extensive display of Galapagos finches -- the kind that inspired Charles Darwin to develop his theory of evolution -- includes no reference to Darwin or explanation for the different shapes of their beaks. The only family tree in the museum shows the modern wolf descending from the cave bear descending from the sabertoothed tiger.
Now, nearly a decade after deciding to refocus its mission on public outreach instead of simply collecting specimens, the museum is slowly starting to update its displays—many of which date back a century or more.
Clearly more science is needed, but it is to be hoped that the revamp doesn't spoil the experience of visiting the museum. There is something very wonderful about old Victorian Natural History museums stuffed full of dead animals in glass cases. The Dublin Natural History Museum is my favourite.
