It's very likely that there's a simple switch (i.e. not much more than a couple of mutations required) which governs finger/toe length in primates. For example, did you know all the DNA for growing a "Lizard Leg" (the ENTIRE leg) is still in all snakes, but just just not activated, because one other mutation is blocking it?
There are many known genetic conditions that we see even in modern times, caused by one or two mutations which can cause very long fingers/toes, and people in this thread are arguing that even in 23000 years nature can't land on that mutation and stick to it, _especially_ when we _know_ the DNA for it is likely still there because we're all apes 98% identical to monkeys for example, which have the long toe thing.
