The twins were now playing in the most approved brotherly fashion
Humans are a social species, we interact with other people – aided by language- and exchange information on daily basis. The effects of social isolation have been demonstrated and predicted to be very severe and “de-humanising” in many cases with a long list of adverse effects on cognitive abilities and emotional stability. The question often posed when considering this feature of mankind is whether it is an adaptation to the presence of others in our environment, a simple product of proximity; or it is a function developmentally wired into our genes and is ,thus, needed for proper growth and development. The latter also would imply the evolutionary advantage of cooperation and living in a group.
In a recent study, researchers tackled the question of whether we are genetically wired to be social, and they did so by finding one of the most controlled environments in human developmental studies, and chose the ideal subjects for most genetic questions. Twins in utero! (…)
The intentional nature of movements directed towards the other twin is an important observation from this study; it suggests that we are , in fact, genetically wired to be social.
