Why is it so rare to be left-handed?
As handedness is a highly heritable trait associated with various medical conditions, and because many of these conditions could have presented a Darwinian fitness challenge in ancestral populations, this indicates left-handedness may have previously been rarer than it currently is, due to natural selection.

How does being left-handed affect a child development?
Recent research suggests that children who are strongly left or right handed also have good cerebral lateralisation and typical language production. On the other hand, mixed-handedness (not developing a dominant hand) has been linked with atypical development of motor and language abilities.
