How did we end up eating three meals a day in the western world, large parts of asisa and africa?
Yes there are cultures which eat only twice, or more often, but the 3 meals policy seams to be far more in use then anything else.
How did that happen?
I usually eat only once a day maybe twice(by hunger), and the early hunter-gatherers may have had problems to do so every day, so what did the agricultural revolution etc. do to us so that we eat 3x a day?
