Some historians think the most important development in human history was ? ?

Most historians definitely believe in agriculture as being the most important addition to human history. This is because without agriculture, and i am being serious now, there would be no meat, there would be no eggs ,or syrup or even the best of all ,pizza. In short, historians have recognized Agriculture as the most popular, and important development of human kind!
Hope this helps

The native americans, spanish, french and americans all name places in our state. the word “arkansas” came from the quapaw indians, by way of early french explorers. at the time of the early french exploration, a tribe of indians, the quapaws, lived west of the mississippi and north of the arkansas river.

Because the discoveries were some of the oldest human remains.
