The species known as Homo floresiensis was previously thought to have a brain volume of 400 cc, but it was actually 426 cc, bringing their brain size to roughly the same as a chimpanzee. That is, compared to about 1500 cc we currently have as Homo sapiens.
Researchers determined the larger brain size with a high-definition CT scanner.
The remnants of the “hobbits” were discovered on the island of Flores, part of Indonesia, in 2003.
The individuals were roughly three and a half feet tall, and had short legs when compared to their arms and feet.
