This newspaper combined foreign media reports and recent reports from the official website of the University of California, Santa Barbara，Recent bet365 free bets by Lynn Gamble, professor of anthropology at the school，Aboriginal ancestors of North America living in what is now California may have used shells as currency 2,000 years ago，This is about 1,200 years earlier than previously expected by scholars。

Previous archaeological scholars believed，The Chumash people, the ancient indigenous people living in California, used wampum as currency dating back at least 800 years ago。However，Gamble’s study of shell bet365 free bets known as saucer bet365 free bets unearthed in the San Francisco Bay Area，Challenges this conclusion。Gamble said，These early dish-shaped bet365 free bets had the same standardized shape as bet365 free bets that appeared 1,000 years later。Through the investigation of different shell bead shapes、Measurement and Standardization Comparison，Can be seen clearly，These bet365 free bets may be coins，And it appeared much earlier than previously thought。

There is now a lot of evidence that，Early shell bet365 free bets, represented by the above-mentioned saucer bet365 free bets, were produced in the Northern Channel Islands，The evidence includes tools for making shell bet365 free bets such as drills，As well as numerous shell fragments scattered on the surface of the island’s archaeological sites。Comprehensive information from various aspects，Gamber thinks，When California Indians first came into contact with Europeans，Just trade many types of goods，The use of shell bet365 free bets undoubtedly greatly contributed to the formation of this extensive exchange network。

Gamble’s bet365 free bets not only redefined the origins of American currency，Also refreshed the old concepts。Because the Chumash people are non-agricultural people who live by hunting and gathering，Long time，People think they don’t need currency。The great significance of this bet365 free bets is，It challenges a long-held view among some economists and archaeologists，That is, the so-called "primitive" society cannot have a commodity economy。
