Would you mind expanding this interesting point for an
interested amateur i.e. the difference between

'common _diffused_ features'

and

'shared innovations inherited from a common ancestor'

with some examples? I have been giving it a little
thought and would greatly appreciated more
explanation.

thanks

Guto
