Some people have dark skin, others don’t, some have long legs, others don’t, some are very strong, others don’t, … During millennia humanity got adapted to the environment by different and slowly and successful mutations in our DNA. Through genetic heritage we have received them generating more than 7.000.000.000 unique combinations of human beings in planet Earth. There is no 2 identical combinations but there are millions of people sharing some gens. This is what happens with DRD4-7R.
Why have some people a gen that whispers them inside their head: “travel, travel, travel…”? It is not a secret that this is also something that happens to both of us. The answer is behind the concept “Survival”.
