A royal thumb, also known as a clubbed thumb, is a rare physical characteristic historically thought of as a sign of royalty, particularly within European bloodlines.
Understanding the Royal Thumb
Historically, this distinctive thumb shape was considered a mark of nobility and purity of blood. It was observed to be significantly more prevalent among royal European families compared to the general population. This unusual trait was sometimes used as a factor in determining an individual's lineage and the perceived pureness of their ancestry.
