There’s a new way for you to check your ancestry — look at your thumb.
New research published in the American Journal of Physical Anthropology suggests that one’s ancestral background can be determined based on the characteristics of their thumbprint, according to phys.org.
The researchers analyzed the fingerprints of 243 individuals — 61 African-American woman, 61 African-American men, 61 European American women and 61 European American men. Researchers specifically looked at the Level 1 (pattern types, ridge counts) and Level 2 (specific variations and ridge splits) details to see if there were any differences.
