With all the technology today, the authors were surprised to read a recent British study that found a connection between the length of a woman's index (2D) and ring (4D) fingers to her athletic ability. Upon further investigation they found that many studies have examined the relationship between the length of the index finger (2D) to the ring finger (4D) and have linked this ratio to such things as human fertility, behavior, and health. Who knew that fingers could provide such a broad range of information? The British study suggested that women with a low 2D:4D ratio would be better athletes than those with a high 2D:4D ratio. As educators, the authors take a research-based approach and incorporate this study into their college freshmen Bio 101 General Biology course. What would their hands reveal?
