In Search of the Wild Fava Bean


14,000-year-old faba seeds contain clues to the timing of the plants' domestication

Seeds from a site in Northern Israel are the ancestors of today's fava beans

Like all food crops, the faba, or fava, bean – a nutritious part of the diet of many cultures  – had a wild ancestor. Wild faba is presumed to be extinct, but Weizmann Institute of Science researchers have now identified 14,000-year-old remains of seeds that offer important clues as to the time and place that this plant grew naturally. Understanding the ecology of the wild plants’ environment and the evolution they underwent in the course of domestication is crucial to improving the biodiversity of the modern crop. The findings were reported in Scientific Reports.

Dr. Elisabetta Boaretto, Head of the “Timing of Cultural Changes” track of the Max Planck-Weizmann Center for Integrative Archaeology and Anthropology, and Dr. Valentina Caracuta, a former postdoctoral fellow in Boaretto’s group who is currently a researcher at the University of Salento-Italy, had previously shown that 10,200-year-old faba beans discovered in three archaeological sites in Lower Galilee were the earliest faba bean ever domesticated.

The new finding – faba seeds from an archaeological site, el-Wad, on Mount Carmel in Northern Israel – came from the earliest levels of an excavation...(Video) Weizmann Institute of Science

Newfound Tusk Belonged to One of the Last Surviving Mammoths in Alaska

A prehistoric campfire and a number of archaeological treasures — including a large tusk of a mammoth, and tools fashioned out of stone and ivory — remained hidden for thousands of years in the Alaskan wilderness until researchers discovered them recently.

Researchers found the 55-inch-long (140 centimeters) mammoth tusk, the largest ever found at a prehistoric site in the state, during a 2016 excavation at the Holzman site, located about 70 miles (110 kilometers) southeast of Fairbanks, Alaska. A radiocarbon dating analysis revealed that the tusk was about 14,000 years old, the researchers told Live Science in an email.

"The radiocarbon dates on this mammoth place it as one of the last surviving mammoths on the mainland," Kathryn Krasinski, a co-principal investigator of the excavation and an adjunct faculty member in the anthropology department at Adelphi University in Garden City, New York, told Live Science in the email.

The research team found the tusk in soil deposits about 5 feet (1.5 meters) underground. Though other sites have ivory fragments, this discovery marks only the second time that researchers have uncovered an entire mammoth tusk from an archaeological site in Alaska, the researchers said.

The findings suggest that the earliest documented people in Alaska likely went out of their way to acquire mammoth ivory, and that they were creating tools with the material, the researchers said. [...] livescience.com / Link 2 (Video
