It's not exactly easy to study the Tasmanian tiger. The marsupial has been extinct for over 80 years, and it wasn't given much scientific attention when it was alive -- settlers saw it as a threat to their livestock, not a curiosity. However, that isn't about to stop scientists from learning more about the sadly neglected species. Researchers have scanned two preserved Tasmanian tiger brains and discovered that the creatures were considerably more intelligent than many thought. While their brains were similar to those of Tasmanian devils, their larger frontal lobes suggest they were better at planning and making decisions. That backs the belief that they were hunters, not scavengers like their genetic cousins.
