Not even accounting for the fact that we're thousands of years
after "Climate Optimum," and things would have been better
in the past, was just watching a documentary and...
So this documentary is discussing wild grain, pre agriculture,
hunter gatherers in the middle east. They claim, or one of
their features experts at least, that a single individual collecting
these wild grains could, in a matter of three weeks, feed up
to four people for a whole year!
That's quite impressive.
"Nomadic Settlers."
See, this would allow people to "Settle" in one place, but for
no more than a year, couple of years TOPS! Because, by
definition, any seed you eat is a seed that never got a chance
to grow. So, every year, every couple of years tops, they over
exploited the grains and had to move on to "Virgin Fields,"
give the old ones time to recover.
Personally? This is what I think Gobekli, on Turkey, was all about.
Think about it. They would wander on back to Gobekli every
year, seasonally, to harvest the natural grains. Which means they
needed someplace to keep it, because they weren't going to
run around carrying a years worth of grain on their backs! The
seemingly religious elements/decorations were probable just
that: Religious! An attempt to summon/ensure supernatural
protection of their haul.
Personal II: I imagine that these grains were most useful in feeding
their livestock! The grains feed the goat, you eat the goat -- everyone
is happy... you more so than the goat.
So these grasses fed the livestock, then they fed the people, with
a focus on the seed rather than the grass.
Drugs?
Wild grasses can be a great source for Ergot, which in turn can be
a potent drug... hallucinations, anyone?
So we have multiple vectors here. Whether they were driven by the
need to feed their livestock, or a desire to see visions or even just
to avoid starvation (like after an outbreak of rabies, or warfare
robbing them of their meat sources), they had reason(s) to exploit
the wild grasses.
