Description:
The brain of Homo floresiensis was assessed by comparing a virtual endocast from the type specimen (LB1) with endocasts from great apes, Homo erectus, Homo sapiens, a human pygmy, a human microcephalic, specimen number Sts 5 (Australopithecus africanus), and specimen number WT 17000 (Paranthropus aethiopicus). Morphometric, allometric, and shape data indicate that LB1 is not a microcephalic or pygmy. LB1's brain/body size ratio scales like that of an australopithecine, but its endocast shape resembles that of Homo erectus. LB1 has derived frontal and temporal lobes and a lunate sulcus in a derived position, which are consistent with capabilities for higher cognitive processing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Falk, Dean -- Hildebolt, Charles -- Smith, Kirk -- Morwood, M J -- Sutikna, Thomas -- Brown, Peter -- Jatmiko -- Saptomo, E Wayhu -- Brunsden, Barry -- Prior, Fred -- New York, N.Y. -- Science. 2005 Apr 8;308(5719):242-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, Florida State University, Tallahassee, FL 32306, USA dfalk@fsu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15749690" target="_blank"〉PubMed〈/a〉
