While in the 21st century, travelling is more accessible than ever before and nearly every individual is able to find their cup of tea, human behaviour has also set clear barriers when it comes to exploring our planet – something that is coded into human DNA.
Yes, that’s right! Scientists have discovered that some people have been blessed (or cursed) with 7R – a restless gene – that has been tied to human migration. Furthermore, studies have shown that 7R makes people more likely to risk, discover new locations, relationships, drugs and even sexual opportunities. We are not encouraging you to test whether you have this gene, eh! However, maybe this exact gene encouraged Christopher Columbus to complete his voyage across the Atlantic Ocean and discover America? One cannot deny that it was a remarkable landmark indicating the start of colonization, i.e. waves of European settlers immigrating to the New World. However, it would be naïve to believe that one gene present in the minority of the world’s population is the only reason for leaving one’s home and going looking for novel adventures abroad.
