I have a sneaking suspicion that these clever Chinese have been doing this artificial man seed for quite some time and, let's face it, there has to be a reason why they all look alike.
Indeed, it seems that anytime you need vast numbers of workers to do something - like build great walls, or railroad building, or Apple needs a few million iPhones built, the Chinese are always right there and ready.
In a very clever marketing strategy, they took to calling them "coolies" - and judging by old photographs they have known about this for perhaps hundreds (or thousands) of years. Perhaps they needed it to survive due to their small tallywhackers.
