An analysis of the 18,000-year-old "hobbit" skull found on the Indonesian island of Flores in 2003 (pictured left, next to a human skull) shows that the tiny creatures were an entirely separate species from modern humans. Some scientists previously thought the fossil may have belonged to an ancient human with a genetic disease. A new study led by Dr. Karen Baab, a biological anthropologist at Stony Brook University, suggests this theory is incorrect. Get more details at findingDulcinea.
