Thomas Sutikna lives with Homo floresiensis

BLOG - On October 28, 2004, a paper was published in Nature describing the dwarf hominin we know today as Homo floresiensis that has shocked the world. The report changed the geographical landscape of early humans that previously stated that the Pleistocene Asia was only represented by two species, Homo erectus and Homo sapiens . The report titled "A new small-bodied hominin from the Late Pleistocene of Flores, Indonesia" written by Peter Brown and Mike J. Morwood from the University of New England with Thomas Sutikna, Raden Pandji Soejono, Jatmiko, E. Wahyu Saptomo and Rokus Awe Due from the National Archaeology Research Institute (ARKENAS), Indonesia, presents more diversity in the genus Homo. “Immediately, my fever vanished.
