Caribou genetics reveal shadow of climate change

Ancient ice ages that shaped modern caribou populations may foretell animals' fate in a warmer world.

When ice sheets marched across North America 20,000 years ago during the Last Glacial Maximum, they devoured liveable areas for caribou and isolated them from their Eurasian relatives for thousands of years.

Now researchers have evidence that such climatic events have sculpted the genetics of North American caribou, which may make the animals unable to adapt to future climate change.
