Job's tears , scientific name Coix lacryma-jobi , also known as adlay or adlay millet , is a tall grain-bearing perennial tropical plant of the family Poaceae grass family. It is native to Southeast Asia , but introduced to Northern China and India in remote antiquity, and elsewhere cultivated in gardens as an annual. It has been naturalized in the southern United States and the New World tropics. In its native environment it is grown at higher elevation areas where rice and corn do not grow well. Job's tears are also commonly sold as Chinese pearl barley. There are two main varieties of the species, one wild and one cultivated.

Phytolith dating AR
The art of the Upper Paleolithic represents the oldest form of prehistoric art. Figurative art is present in Europe and Southeast Asia , beginning between about 40, to 35, years ago. This latter estimate is due to a controversial study based on uranium-thorium dating , which would imply Neanderthal authorship and qualify as art of the Middle Paleolithic. The emergence of figurative art has been interpreted as reflecting the emergence of full behavioral modernity , and is part of the defining characteristics separating the Upper Paleolithic from the Middle Paleolithic. This has been taken to suggest an artistic tradition dating to more than 50, years ago, spread along the southern coast of Eurasia in the original coastal migration movement.
