Although most people are righties, there are some rare cases that include the opposite situation.

Sometimes we wonder if this feature is the result of some preference or perhaps it’s a habit or a neurological ‘setting’ that we can’t control.

The answer behind this mystery might eliminate the outdated myth that suggests lefties are evil persons.

As suggested by a study published in eLife, this fact is not influenced by our neurological evolution and, in fact, it’s related to our genetic development.

Leftie or Righty?

Researchers claim that being a leftie or a righty is, in fact, a characteristic established before our birth. and it’s generated by a genetic activity developed in our spine and not in our brain.

This characteristic is generated by a genetic activity developed in our spine and not in our brain.

‘Our data suggest the beginning of a hemispheric asymmetry, which unfolds in the spine’, says one of the experts.

The team includes scientists from Germany, Netherlands and South Africa, who monitored the genetic expression of the embryonic activity located in the spinal cord, between the 8^th and 12^th month of pregnancy.

For a long time, the doctors believed the genetic activity unfolded in the brain decides if someone is a leftie or a righty.

However, these new studies contradict the rumors and indicate the presence of some asymmetries.

Moreover, a different evolution has nothing to do with our genetic heritage.

It’s influenced by external factors, which affect the baby while he is in the uterus.
