For crying out loud! Open a book once a year or so.
The word is "acorn": how much more obvious can you get???

I am the proud owner of some Burr Oak, Quercus macrocarpa (forgive the
spelling if wrong). Anyway, recently I am thinking about my Burr Oak as
to harvesting some of the wood since they are too old and I need to make
more room for other trees.

But what I was wondering the most about was why human civilization is
based on wheat, rice, potatoes, corn and several other staples. But why not
oak acorns? It would be much easier every year to harvest oak acorns and to
make it into a bread. Rather than spend so much time on the "annual crops".
And oak in most of human history has covered most of the Temperate climates
so there is not a question of paucity of oak and acorns.

a good idea. Why don't you?

one of the facts that would bother me would be the fact that humanity never
really made much use of the oak acorn. It seems to me that humanity could
have based itself on oak acorns more than on wheat or rice.

I guess the answer lies in the taste. I guess that oak acorns are rather
unpalatable.

Many times in the past 10 years of my Internet posting I said that if
aliens existed on other planets and were in communication with each
other. I said that the main thing is that those aliens have more in common
with each other than they have differences. Not that they can mate with one
another if given a chance, because the differences are larger than species
DNA. But this Burr Oak idea is a nice example of differences between aliens.
Here on Earth, the staples are wheat, rice, corn, potatoes. But I would
wager to guess that on many alien planets should they exist that many of
those alien civilizations have staples not of annuals but of perenials such
as a Oak analog.
