Shakya made the discovery after he had returned to LSU from an expedition to Sumatra. He was sequencing the DNA of several bird specimens from Sumatra and Borneo to compare them when he discovered that the white-eyed bulbuls from Borneo were genetically distinct. 2019–20 | 3 “This discovery was made due to Subir’s dogged detective work The discovery of these high-quality materials—jadeite and and a little serendipity,” said co-author Fred Sheldon, the LSU rosewood—used as utilitarian tools, demonstrates that Museum of Natural Science curator of genetic resources and salt workers played an important role in the Classic Maya Shakya’s PhD advisor. marketplace economy more than 1,000 years ago.

Salt: Mover and Shaker in Ancient Maya Society Salt is essential for life and a biological necessity. However, as ancient civilizations evolved from hunters and gatherers to agrarian societies, it has not been clear how people acquired this mineral.
