No. First you can't easily gather wheat. Prior to man's selective breeding,
all of the seeds spontaneously fell off when ripe. And with their points
they would stick into the ground. Then processing is required to make the
seeds edible. They have to be ground. Grinding leaves behinds tools as
evidence. The evidence found so far is in the Near East they started
gathering grains 17,000 years ago. Some have argued that they ground the
grains with their teeth. Well, maybe, but you couldn't have consumed more
than a token amount of them.
