The idea really isn't that far-fetched as the remains of the people who died in the caves are likely to still be there, albeit ground up in to tiny fragments of bone and mixed in with the dust and dirt.Incredibly, the researchers have already succeeded in locating some ancient human DNA using this technique however there is still a long way to go before it will be possible to fully analyze it.

The next step will be to develop the techniques needed to determine exactly where each sample originated as well as to piece together a more complete picture of a particular species.

"We've been recently trying to explore new sources of ancient human DNA as the fossil record is very limited," said Meyer. "You just take a shovel with some dirt, and then you look for DNA."
