From Atlas Obscura:
MANY OF THE RESIDENTS OF Michigan’s Isle Royale, an archipelago in Lake Superior, are moose. They tromp through the forest to nibble on thimbleberries, or stoop in creeks to slurp aquatic plants. Their ranks have tripled in the past decade, and, just as steadily, their skulls have shrunk. Now, scientists from Michigan Technological University are studying these bones to see what they might reveal about how the animals are adjusting to a warming world.
