"Last year we discovered amphibious and toothless rats on the island too," Rowe explained to the BBC. "There is a remarkable morphological evolution going on there."
If by "morphological evolution" Rowe means rodents who develop insanely long, vampire-style teeth, we can heartily agree.
Sulawesi Island sounds like a remarkable place indeed.
