Your ring-to-index finger ratio can tell a lot about what you’re good at and even what mental disorders you are prone to.
The eyes may be the window to the soul, but the hands can tell you a lot about a person too. Whether they are calloused for instance, or cotton soft. The fingers in particular can give you further insights. A collaborative study conducted by Oxford and Northumbria researchers in the UK, found that differences in the lengths of certain fingers indicated whether a person tended to be more promiscuous or monogamous by nature. The secret lies with the ring finger in comparison to the index.
A new study sheds light on the evolutionary connection between fish fins and human fingers.
While there are a number of theories of how life on Earth began (perhaps in hydrothermal vents at the bottom of oceans), one hypothesis is that eventually the early life forms transformed into something between fish and lizards, developing an ability to walk on land. Filling in some crucial details in this idea, researchers from the University of Chicago now showed that human hands have an evolutionary connection to fish fins.
