LB1 and Homo sapiens
After LB1's discovery, some scientists had suggested that the hobbit was really a modern human, just a small one. But when Falk's team measured the brains of LB1 and Homo sapiens, they confirmed what seems obvious to the eye—the two brains are very differently shaped. In addition, LB1's body-size-to-brain-size ratio doesn't match that of a human dwarf. When H. sapiens bodies shrink, the brain and head stay relatively large. That's not the case with LB1—her brain and head are small in proportion to her body. LB1's brain also bears little resemblance to that of a human pygmy, the team noted.
