Article: Periodically "clean slate" decrees were signed by rulers which cancelled all the rural (but not commercial) debt and allowed bondservants to return to their homes. Customarily rulers did it at the beginning of the first full year of their reign, but they could also be proclaimed at times of military conflict or crop failure. The first known ones were made by Enmetena and Urukagina of Lagash in 2400-2350 BC. According to Hudson, the purpose of these decrees was to prevent debts mounting to a degree that they threatened fighting force which could happen if peasants lost the subsistence land or became bondservants due to the inability to repay the debt.

Question: Who made the first known clean slate decrees?
Ans: Enmetena and Urukagina

Here is a question about this article: In 1978, Sewall Wright suggested that human populations that have long inhabited separated parts of the world should, in general, be considered different subspecies by the usual criterion that most individuals of such populations can be allocated correctly by inspection. Wright argued that it does not require a trained anthropologist to classify an array of Englishmen, West Africans, and Chinese with 100% accuracy by features, skin color, and type of hair despite so much variability within each of these groups that every individual can easily be distinguished from every other. However, it is customary to use the term race rather than subspecies for the major subdivisions of the human species as well as for minor ones.
What is the answer to this question: When did Sewall Wright make his suggestion about human populations?
****
So... 1978
