Left handedness

Here is a rather old TV programme that deal with the idea of left handedness and the connection to dyslexia




There is a theory that left handed people are womb twin survivors. They are the sole survivors of "mirror" twinning.

The idea is that monozygotic twins are one zygote split into two, and it can happen that the twins are  mirror images of one another. If the righthanded one is the one to die, then the left handed one will be the sole survivor.
