Size of the ideal smartphone screen size is limited by human hand. Couple of years ago, Apple did extensive tests and found out that 3,5" is the perfect size of smartphone screen. However, latest research revealed something amazing.
New iPhone has half inch bigger screen, yet it also perfectly fits human hand. How is that possible? There is only one logical explanation: human thumb grew by half inch since the introduction of the original iPhone. But why?
Hidden force behind that are Android phones. Bigger and bigger screens forced people to stretch their thumbs more and more. As this is repeated hundreds of time per day, human thumb become longer. The most amazing thing about this discovery is that such huge change happened in such short timespan, while typically it would take life forms with more rapid generation shift than humans to evolve so fast.
