People have always wondered why some people are born left-handed. Until now, researchers can not come to a consensus. However, recent research suggests that left-handedness can be inherited.
True, until experts have found out who the carrier of this gene is. It is known only that among men, left-handers are more common than among women. In support of this theory, the fact that the adoptive kids, in which one of the parents was left-handed, even if right-handed parents raised him, still became left-handed, also confirms this.
