^ This is not a correct timeline for wheat consumption of corn for that matter. Forms of wheat have been consumed by humans for 11,500 years and corn has been eaten for around 9,000 years.
Mmmm....5000 maybe? At best? Sources?
Regardless, even 12,000 is still only about 500 generations....not much in evolutionary terms.
You want sources? Here ya go, hun.
After doing a scholar.google.com search here are some sources:
The article below is by an author who is of the opinion that wheat consumption dates back as far as 15,000 years ago:

Another scholar.google.com source that asserts that wheat cultivate dates back as far as 10,000 years ago:

However, if I were to do a standard google.com search the search becomes quite numerous. Regardless, the time lines seem to be in sync somewhat so I'm guessing there is a level of accuracy using either search engine.
