Real History: The Lemon was "invented" in Asia

This information has almost no relevance for playing RPGs but just another interesting piece of evidence for South East Asia being very important in early human history.

The lemon is a human invention that’s maybe only a few thousand years old.

The first lemons came from East Asia, possibly southern China or Burma.  (These days, some prefer to refer to Burma as Myanmar.  I’ll try to stay out of that controversy here and stick to fruit.)  The exact date of the lemon’s first cultivation is not known, but scientists figure it’s been around for more than 4,000 years.  The lemon is a cross breed of several fruits.
