Hi Ev,

I think your question is pretty straight forward to answer:
axons can develop branches (same as dendrites do) and thereby 'supply'
many dendrites/neurons with input.

This is a more tricky one, but my impression is that 'humor' is the way of
a logical(?) brain to cope with certain inconsistencies (internal or
external) that cannot be solved otherwise. As such it (humor) could be
something that 'emerged' with increasing complexity of the brain. So maybe
humor is a sign of intelligence. I really like that thought, but there's a
lot of really stupid jokes and jokers.
