Compare the Brains
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.
