"Taco" tongue fold in Seminole Indians
Summary
Two Florida Seminole individuals can longitudinally fold their tongues. This unique tongue-folding ability can be oriented to the left or right side.
Area of Science:
- Human genetics
- Physiology
- Anthropology
Background:
- Tongue-folding is a heritable trait studied in human genetics.
- Previous research suggests a dominant gene may control tongue-rolling ability.
Purpose of the Study:
- To document and describe a specific instance of longitudinal tongue folding.
- To observe the directional orientation of this folding ability in individuals.
Main Methods:
- Observational study of two individuals from the Florida Seminole tribe.
- Demonstration and recording of tongue-folding capabilities.
Main Results:
- Two Florida Seminole individuals exhibited the capacity for longitudinal tongue folding.
- The folding could be performed with the opening directed either to the right or left.
Conclusions:
- This case provides further evidence of variations in human tongue manipulation.
- The observed directional control in tongue folding warrants further investigation into its genetic and neurological underpinnings.
