Homo Floresiensis

  1. 1. Homo Floresiensis By Matthew Winter, Will Mairs, and Cindy Cochran
  2. 2. Homo Floresiensis <ul><ul><li>Homo Floresiensis are a possible species in the genus Homo. </li></ul></ul><ul><ul><li>They have a remarkably small body and brain. </li></ul></ul><ul><ul><li>Two skeletons were found in the island Flores, were dated back to 18,000 years </li></ul></ul><ul><ul><li>The early hominid, know by scientists as LB1(or the hobbit), is comparatively a dwarf, standing at just over a meter tall. Careful observations have shown that LB1 had a brain roughly 2/3 the size of a modern human’s. </li></ul></ul><ul><ul><li>  </li></ul></ul>
  3. 3. Comparisons to Humans <ul><ul><li>LB1 (one of the skeletons) has many ape-like features, and many human-like features </li></ul></ul><ul><ul><li>Their brain was the size of a chimpanzee, but had features to help their cognitive ability </li></ul></ul><ul><ul><li>  Their brain cavity had an enlarged Broadmann area 10 </li></ul></ul><ul><ul><li>  That part of the brain allows complex thoughts e.g. making tools </li></ul></ul><ul><ul><li>  This allowed them to be as advanced as Humans, even with a brain the size of a chimp </li></ul></ul>
  4. 4. Is this all real? <ul><ul><li>Scientists believe that LB1 was the result of a disease </li></ul></ul><ul><ul><li>  Fossil Evidence supports the theory because there were more advanced hominids at the time </li></ul></ul><ul><ul><li>But the wrist of LB1 is like an african ape </li></ul></ul><ul><ul><li>In modern humans the wrist bone is like a boot, but in LB1 it is a pyramid </li></ul></ul><ul><ul><li>  </li></ul></ul>
  5. 5. The Lord of the Rings wasn't too far off with the &quot;hobbit&quot;
  6. 6. Other Facts <ul><ul><li>Evidence suggests that the species lived until about 12,000 years ago, making them the longest surviving hominid </li></ul></ul><ul><ul><li>Some individuals were born without a thyroid, possibly causing growth failure, or mental retardation </li></ul></ul>
  7. 7. Acknowledgments <ul><li>For Information and pictures: </li></ul><ul><li>http://en.wikipedia.org/wiki/Homo_floresiensis#Discovery   </li></ul><ul><li>Original article from Scientific American November Issue </li></ul>
