Karen Baab, Ph.D at Stony Brook University and collegues have come to the conclusion that the 2003 fossil found in Indonesia is not “human”. If their research holds up, it would be a remarkable admission, that another “Species” existed on Earth at the same time as Homo Sapiens.
“…To carry out the study, Dr. Baab and colleagues collected 3D landmark data on the LB1 skull and a large sample of fossils representing other extinct hominin species, as well as a comparative sample of modern humans and apes. They performed several analyses of different regions of the skulls. Taken together, these analyses indicated that the LB1 skull shape is that of a scaled down Homo fossil not a scaled down modern human.
The results of the analysis of the asymmetry of the skulls, which refers to differences between the right and left sides of the skull, refutes the suggestion that the LB1 skull was that of a modern human with a diagnosis of microcephaly. In modern humans, a high degree of asymmetry may indicate that the individual was diseased. At least one scientific study on the asymmetry of LB1 supported the argument that this individual had microcephaly. Conversely, Dr. Baab and colleagues found the degree of asymmetry of the LB1 skull was not unexpectedly high and therefore not supportive of the diagnosis of microcephaly.
“The degree of asymmetry in LB1 was within the range of apes and was very similar to that seen in other fossil skulls,” says Dr. Baab. “We suggest that the degree of asymmetry is within expectations for this population of hominins, particular given that the conditions of the cave in Indonesia in which the skull was preserved may have contributed to asymmetry.”
Dr. Baab recognizes that the controversy as to the evolutionary origins of Homo floresiensis will continue, perhaps without an answer. However, all the evidence that she and colleagues illustrate in their article “Size, shape, and asymmetry in fossil hominins: The status of the LB1cranium based on 3D morphometric analyses,” suggest that Homo floresiensis was most likely the diminutive descendant of a species of archaic Homo…”
