Scientists have re-examined Mastadon bones found in the San Diego area in 1992. They find the bones to be over 100,000 years old. Moreover, the bones appear to have been broken by humans. This means that modern humans may have travelled to North America fare earlier than is commonly accepted, which is about 15,000 years ago.
