Presentation Transcript

  1. Daisuke Kubo University of Tokyo • Graduate School of ScienceDepartment of Biological Sciences

  2. Research? • Anthropology • Brain size • The evolution of brain size

  3. Homo floresiensis The Hobbit People

  4. Height Difference

  5. Flores Islands

  6. 9 remains 1 intact skull • LB1 (Liang bua)

  7. And tools?

  8. Demonstration

  9. 1/3

  10. Where did it come from?

  11. “ Brain size of Homo floresiensis and its evolutionary implication”

  12. Two Hypotheses

  13. I • Floresiensis brain reductions • From Homo erectus 1000cc • To 426cc

  14. II • Floresiensisevolved from ancestor • From Homo habilis or Australopithecus 600-400cc • To 426cc

  15. How were we to test this?

  16. 1 Calculations • 2 Preparation, preservation and alteration of the cranium. • 3 reconstruction of cranium and possible errors.

  17. Results

  18. What did we confirm?

  19. Yes Javaman

  20. Argue

  21. Microcephaly

  22. Tools? Hunting?

  23. DNA Analysis

  24. Teeth Size

  25. Island Insular Environment

  26. Continued Research?

  27. Questions? Thank you for your time.
