    ''What scientists, who, what field of science? What are their names?''

    I don't think that you are willing to accept anything that does not conform to your beliefs....however, as an example;
    Quote:
    In China, the use of the cowrie shell as a currency is attested during the Neolithic area. Due to its scarcity, imitations of the shell have been found made from jade, stone, bone, earthenware, gold, tin, and bronze in many archaeological sites. This type of shell was found in Oceania, Africa and in the Middle and Far East, with varying value depending on the distance traveled to collect it. As a matter of fact, this very type of shell is still used as a currency in Ethiopia and remote regions of Africa nowadays (Davies, 1994).
