Post-flight feast: Study suggests reindeer vision evolved to spot favorite food

Rudolph the red-nosed reindeer may have millions of carrots set out for him on Christmas Eve, but what about the rest of the year? Finding food in a cold, barren landscape is challenging, but researchers from Dartmouth College in New Hampshire and the University of St. Andrews in Scotland report that reindeer eyes may have evolved to allow them to easily spot their preferred meal. It's further evidence that while reindeer are famous for pulling Santa’s sleigh, it’s their vision that really sets them apart, says Nathaniel Dominy, a Dartmouth anthropology professor and co-author of a recent study published in the journal i-Perception.
