Texas A&M researchers have literally unraveled some of the mystery behind ancient civilizations.
Dr. Chuck Kennicutt was among a team of researchers who examined the tar used to embalm mummies more than 3,000 years ago.
The group discovered the tar originated hundreds of miles away from Egypt.
Meaning Egyptians had a trade route similar to what we have today.
"There's still quite a bit of controversy over whether there was active trade in the region and this just shows that in fact tar was transported as a commodity relatively large distances," says Kennicutt.
The discovery also means Egyptian trade routes are older than previously thought.
