There are some people who never feel the need to leave their house. They are happy to stay in the city where they live, and may go on one or the other walk when they are on vacation from work or school. But for them the best place is the space that occupies their favorite room.
The opposite end is occupied by those who can not remain still. Those who bring their current passports and visas, just in case.
If you are passionate about traveling, the love of knowing different places or the old one curiosity different ways of referring to the same, you are someone whose hunger to explore simply can not be turned off, no matter how many times you take vacations, or trips.
For you, there is always something new to see, something different! Even on day trips you realize how many things you can see in 24 hours. You have one-way flights, and trips without specific destinations.
Because you do not like the whole planning issue. Plans imply a purpose, and in your experience, traveling without one always implies more emotion. It has been like that since you can remember, which probably goes back to the first trips when you grew up as a family, when you were a child.
What you did not know is that, according to recent scientific research, this may have been incorporated into your DNA. As mentioned in a psychology blog, the impulse to travel is remote to the so-called DRD4, which is associated with the levels of dopamine in the brain.
The DRD4-7R gene has been dubbed as a passion gene for travel due to the correlation with increased levels of curiosity and restlessness. However, the reality is that those who carry this genetic information usually share a common theme: the history of travel.
The gene exists in approximately 20 percent of the population, and its presence stands out in the regions of the world where travel has been fostered since the past.
Assuming that all forms of human life originated in Africa, Chuansheng Chen, a professor at the University of Michigan, in the United States, conducted a study in 1999 that would support the premise that the DRD4-7R gene is more likely to exist in societies where people migrated from longer distances, thousands of years ago.
David Dibbs, from the magazine National Geographic, He supported these findings and the link between curiosity and restlessness, expressed concretely in the passion for travel.
According to Dobbs, the way it mutates the DRD4-7R gene causes people to be more likely to take risks, explore new places, ideas, food products, relationships, medicines or sexual opportunities. The carriers of this gene usually embrace movement, change and adventure.
Dobbs also associates this gene with human migration. Compared to sedentary populations, or those who have remained in the same region for most of their existence, members of migrant populations present these days, and those with a history of relocation, tend to over time to carry and transmit the gene.
Dobbs highlights in his study that the R7 gene with a second genetic variant (R2) tends to be found more frequently than expected in populations whose ancestors migrated. All this being said, there is no reason to doubt this travel gene, except for the mind of Kenneth Kidd, a researcher at Yale University, who argues that genetics does not work that way and can not reduce something as complex as exploration. human to a single gene.
Dobbs, however, adds the factor that the human capacity to explore lies in the function of two systems: the extremities and the brain. With respect to humans, there are some differences in our limbs and brains that can distinguish us from our most common ancestors (even though our genetic construction remains almost identical to that of apes, despite the visual differences in our anatomy).
The legs and hips allow us to walk long distances; we have clever hands and a smarter brain that grows much more slowly, but much larger than the brains of other primates. These characteristics allow us to be trained, as a species, to travel long distances and explore creatively.
The DRD4-7R gene could be linked to Neanderthal behavior in general, converting the carriers of this genetic variant into incredibly ingenious, pioneering and creative beings, and more willing to travel passion, albeit impulsively.
So if you notice that you have a frequent temptation to travel in the next few months, stop and make sure you are thinking rationally. This is not fought with what we have said before: traveling is always more fun without a plan.
