This is a stupid statement, if you were a nomadic tribe you buried people where they were when they died, whether it was near home or not. If your nomadic then you live in a general area. Perhaps you are collecting eggs bye the ocean during the spring time when the gulls roost or you could be in the highlands during the summer to collect berries and follow prey. So when you are nomadic, wherever you are is where you live and when you die you are always close to your home, unless your remains are to be interred elsewhere like Indian burial mounds.
Not true, nomads cover huge areas of land each year following the food. Where ever they die is "near home" alright but simply because they found a body there doesn't mean a city was thriving at that time. Nomads don't build cities. The whole point of the article was to state that that city had been the center of human culture many years longer than originally thought, simply because they found one grave. My statement called them on it, because nomadic tribes buried people where ever they happened to be at the time.
Since only one body was found, I assume that they were passing by and buried this woman where she fell. Were a city present at that time many other bodies or pieces of them would have been found by now.
