3D technology is unlocking the secrets of the Tasmanian Tiger an extinct marsupial with a surprisingly canine appearance. Scientists are hoping the scans will help explain why the creature evolved to look so much like a dog, even though the two species last shared a common ancestor some 160 million years ago. This is a computer-generated model of a young Tasmanian tiger, also known as a thylacine. The computer model was created after scanning 11 preserved Tasmanian tiger joeys aged from just a few days old to fully grown juveniles. The team is hoping the scans will provide new clues as to why the Tasmanian tiger evolved to appear so similar to a dog, even though they last shared a common ancestor some 160 million years ago.
