Associations between dermatoglyphic variation, topography, and climate in Kenya
American Journal of Physical Anthropology
|November 1, 1985
Summary
Dermatoglyphic traits in Kenyan populations show significant correlations with altitude and rainfall. These findings suggest a link between climate and fingerprint patterns, contrasting with previous studies in sub-Saharan Africa.
Area of Science:
- Human genetics
- Anthropometry
- Climate science
Background:
- Dermatoglyphics, the study of skin patterns, is used to understand human population variation.
- Previous research on dermatoglyphic variation and climate in sub-Saharan Africa yielded inconclusive results.
Purpose of the Study:
- To investigate correlations between dermatoglyphic traits and climatic factors (altitude, rainfall) in Kenyan populations.
- To compare findings with existing literature on dermatoglyphic variation and climate.
Main Methods:
- Analysis of dermatoglyphic finger and palmar traits from 57 male and 53 female Kenyan individuals.
- Statistical correlation analysis with altitude and mean annual rainfall data.
Main Results:
- Significant correlations were found between dermatoglyphic traits and climatic variables across the full sample range.
- These correlations remained significant even when analyzing smaller, independent population groups.
Conclusions:
- Climate, specifically altitude and rainfall, appears to be a significant factor influencing dermatoglyphic variation in Kenyan populations.
- The study highlights a potential link between environmental factors and human genetic traits, challenging previous findings in the region.
