A new research has disclosed that genes present in human body might have something to do with facial recognition.

Researchers discovered that identical twins were twice as similar to each other in terms of their capability to identify faces as compared to non-identical twins.

They also set up that the hereditary effects that let people to distinguish faces are connected to a highly specific system in the brain, unrelated to the organ's capability to identify words or abstractionism.

Study co-author Brad Duchaine from the University College London (UCL) said, "Face recognition is a skill that we depend on daily and considerable variability exists in the ability to recognise faces."

"Our results show that genetic differences are responsible for the great majority of the difference in face recognition ability between people," Duchaine added.

The research comprised 164 identical twins, who share all their genes, and 125 non-identical same-sex twins, who share 50% of their genes.

All the partakers took the Cambridge Face Memory Test that assesses the capability to learn six faces and then identify them in new poses and lighting.

These results were published in the Proceedings of the National Academy of Sciences. (With Input from Agencies)
