Resumo

The plow is one of those seminal inventions which has transformed history; unfortunately, we have little archaeological evidence about its origins. We believe that the plow existed 4,000 years ago in both ancient Sumar and Egypt, but we do not know when it was first introduced, or where, or by whom. It arrived in human history without fanfare and was an integral part of complex technological and social systems by the era from which we have first evidence of its presence.
