Diver Gemma Smith brings up bones from the Antikythera wreck.

The individuals found at Antikythera could be from the crew, which would probably have consisted of 15–20 people on a ship this size. Greek and Roman merchant ships also commonly carried passengers, and sometimes slaves. One reason people get trapped inside shipwrecks is if they are chained, points out Dunkley. “The crew would be able to get off relatively fast. Those shackled would have no opportunity to escape.” Intriguingly, the recently discovered bones were surrounded by corroded iron objects, so far unidentified; the iron oxide has stained the bones amber red.

Schroeder says that because ancient underwater remains are so rare, DNA analysis on such samples using state-of-the-art techniques has barely been tried. (Analyses were conducted on skeletons from the Mary Rose and the Vasa, but specialists no longer see those methods — based on amplifying DNA using a method called PCR — as reliable, because it is too difficult to distinguish ancient DNA from modern contamination.) Exceptions include analyses on 8,000-year-old wheat from a submerged site off the English coast (although these results have been questioned because the DNA did not show the expected age-related damage4), and mitochondrial DNA from a 12,000-year-old skeleton found in a freshwater sinkhole in Mexico5.
