For some people, waking up in the morning is the ultimate definition of a chore, especially if one tends to be more productive or creative late in the evening. To some, it may seem like personal preference, but a new study suggests that being a “night owl” can be chalked up to gene mutations.

Researchers analyzed a total of 70 subjects from six families, and, as Live Science reported, some of the subjects were found to have a condition called delayed sleep phase disorder, or DSPD. This is a condition where the body clock tends to lag behind that of the average person, causing sufferers to sleep late and wake up similarly late. Based on the research, those with DSPD had a “night owl” gene mutation in the CRY1 gene, one that wasn’t present in family members who didn’t have DSPD.
