> ...coulld we push agriculture towards "paleolikeness" ?

there is an extensive system of agriculture which, at least from my very
cursory level of knowledge, seems to be
more paleo than other methods.

check out Bill Mollison's (sp?) PERMACULTURE from Australia.

i don't know if there's any info online. i've just seen the books in the
past.

for example, you don't prune the fruit trees -- because that's not their
natural state.
