Paul, I like your scenario. It includes a very useful level of
detail for how the shore environment fits into the development
of bipedalism.

I wonder though why you think it is signnificant that
" There is no need to rely on
geological events for the separation or expansion of the species."

There were seal level fluctuations that turned highlands into
islands during the correct time period, so the events need not
be "invented". Speciation is much easier on islands as Darwin
observed.
