Why Are Animals Becoming More Nocturnal?

Research out of UC Berkeley shows that animals around the world are becoming more nocturnal in response to human populations.

The study, published in the journal Science in June, found that mammals have, on average, become 1.36 times more active at night. In other words, a creature that normally would have split its activities equally between day and night, now carries out 68 percent of its activities at night, presumably in avoidance of humans.
