Most of us are right handed, with only approximately ten percent of the population of the UK, and the world at large, being left handed. But why that is so remains a mystery.
The fact that taller people also tend to be slightly smarter is due in roughly equal parts to two phenomena—the same genes affect both traits and taller people are more likely than average to mate with smarter people and vice versa—according to a study led by the University of Colorado Boulder.

The basis of autism spectrum disorder is long known to have a strong genetic component, however new research is suggesting that environmental factors may play an equally important role in this developmental disorder affecting nearly one in 100 children.
The largest and most rigorous twin study of its kind to date has found that shared environment influences susceptibility to autism more than previously thought.
