There are people who are completely content with the lives into which they were born,who never feel the urge to leave their house. And then there are those yearning to explore and discover the world. Whether you call it a love of travel or regular curiosity the fact remains the same. The hunger to explore simply cannot be quenched, no matter how many journeys one takes.
What exactly drives them to travel so much? What gives rise to the madness to explore?
According to scientific findings , it may have been embedded in their DNA, even before that!
In reality,those who carry this genetic information typically share one common theme, a history of traveling. But this gene is not all too common in fact, it’s only possessed by about 20 percent of the population. Having said that, there is a much higher prevalence of this gene in regions of the globe where travel has been encouraged in its past.
Chaunsheng Chen of Africa conducted a study in 1999, that supported the premise that “the DRD4-7r form of the gene, more likely to occur in modern day societies where people migrated longer differences from where we first originated in Africa many thousands of years ago.” A research was done which supported these findings. They called it “Restless gene”
According to David Dobbs of National Geographic, there is mutation within our genome which continues to pop up when discussing the urge to explore.The DRD4 gene helps to control dopamine levels in our brain. A alternate form of this gene, known as DRD4-7R, has been repeatedly tied to higher levels of restlessness or curiosity .In line with Chan, Dobbs also linked the 7r mutation of the DRD4 gene to human migration.
When compared to the populations who have stayed in the same region for most of their existence, members of present day migratory populations – those with a history of relocating, over time – tend to carry the 7r gene much more commonly.It was also found that those who carry this 7R gene tend to be higher risk takers, and crave change and adventure, they explore new places, foods, ideas, relationships, drugs, and sexual opportunities. As long as the 7R gene is present in one’s genome, they are never going to stop pushing the limits,never going to stop traveling,never going to settle in one place!
Great news for living long! Findings were published in the Journal of Neuroscience, stating that there are significantly higher rates of the 7R gene in people older than 90.
So, while one might have an the urge to quit work and travel for the next few months and people call you escaping from the real world. You can stop and make sure you’re thinking rationally. Traveling is always more fun without a plan.
