Ancient Origins – In May last year, archaeologists made the announcement that a complete Ice Age skeleton had been found in an underwater cave in Tulum. Since then, more than eight well-preserved skeletons, ranging in age from 9,000 to 13,000 years have been retrieved from cenotes in Mexico and now scientists are beginning to unravel the secrets that they hold, remaining hopeful that the bones may eventually reveal how the Americas were first populated.
