"Wanderlust" Gene - Is this gene in your DNA?

You know them when you meet them: those people who always keep their passport on hand, who can pack for an international trip in about twenty minutes flat, who’ve almost never met a travel idea they didn’t like, who would rather take three international trips a year than get a new car. They never get tired of exploring.

Scientists might have discovered why some people tend towards wanderlust and others don’t. 

 One gene in particular, simply known as DRD4, is associated with dopamine levels in the brain. Dopamine is one of the brain’s natural “feel good” reward chemicals. For example, it’s released when we eat a delicious piece of chocolate cake or when we win at a race after training for months. 

 A derivative of DRD4, called DRD4-7R, is what’s come to be known as the “wanderlust gene.” In people who have it — only about 20 percent of the population — it shows up with an increased curiosity, restlessness, and desire to explore. And the one thing that almost all people who have DRD4-7R share in common? A history of traveling.

 While nailing down the urge to explore and travel to only one piece of DNA might seem a bit simplistic, part of this unique gene mutation might be linked to the fact that the human brain and body are uniquely suited for exploration: unlike other primates, we have legs and hips that are designed to walk long distances; we have hands that can perform incredibly detailed tasks; and our brains are large and are naturally wired for creativity and change. Another source of the 7R gene might be those people groups in human history that experienced mass migration over long distances — they cultivated and passed on a reentless curiosity about new territory because that was what they were doing for generations.

David Dobbs of National Geographic explored the question of the “travel gene” more in depth in a 2013 article. Regardless of its origin, Dobbs notes that people who possess the 7R mutation are people who are “more likely to take risks [and] generally embrace movement, change, and adventure.”

Sound like someone you know?

I definitely do! I married this free-spirit traveler.  She has traveled the globe. Her “wanderlust” gene inspired me to start a travel company.  I knew that others have this same gene and traveling brings those people great joy as it does her. And even if you don’t have this specific gene, there is something in most of us that gives us the desire to explore.
