Question

Is there any chance of getting our ancestors finger prints to us

Answer 1

A proof-of-concept study finds that it is possible to identify an individual's ancestral background based on his or her fingerprint characteristics – a discovery with significant applications for law enforcement and anthropological research.

"This is the first study to look at this issue at this level of detail, and the findings are extremely promising," says Ann Ross, a professor of anthropology at North Carolina State University and senior author of a paper describing the work. "But more work needs to be done. We need to look at a much larger sample size and evaluate individuals from more diverse ancestral backgrounds."
Anthropologists have looked at fingerprints for years, because they are interested in human variation. But this research has looked at Level 1 details, such as pattern types and ridge counts. Forensic fingerprint analysis, which is used in criminal justice contexts, looks at Level 2 details – the more specific variations, such as bifurcations, where a fingerprint ridge splits.
For this study, researchers looked at Level 1 and Level 2 details of right index-finger fingerprints for 243 individuals: 61 African American women; 61 African American men; 61 European American women; and 60 European American men. The fingerprints were analyzed to determine whether there were patterns that were specific to either sex or ancestral background.
The researchers found no significant differences between men and women, but did find significant differences in the Level 2 details of fingerprints between people of European American and African American ancestry.
