Despite humans (Homo genus) having existed for 2.5 million years, the earliest evidence we have of shelling was found by archeologists excavating 30,000-year-old Homo sapiens sites in the European Mainland. As of today, the oldest known instruments came from bones, fashioned into early forms of flutes. Cone types are the other general shape.
