  1. The Biology and Origins of LanguagePart 2

  2. Tonal Language Example Mandarin Tone Use Word Intonation Meaning ba [/] to uproot ba [--] eight ba [\/] to hold ba [\] a harrow

  3. Genes and Language The newer version of ASPM is traced back to 5800 years ago. The newer version of Microcephalin is traced back to 37,000 years ago. (Dan Dediu and Robert Ladd of the University of Edinburgh, Scotland, May 2007)

  4. When did language first appear in humans? ?????????

  5. Fossil Evidence for Language1

  6. Australopithicines Australopithecines lived between 5 and 2 million years ago. (Artists rendition based on skeletal and muscular reconstruction.)

  8. Fossil Evidence for Language2

  9. Fossil Evidence for Language3

  10. Australopithecus vs. Homo habilis Homo habilis 600 cc Australopithecus 400 cc

  11. Fossil Evidence for Language4

  12. Homo erectus Homo erectus lived between 1.5 and .5 million years ago. They hunted large game and gathered plant foods. (Artists rendition based on skeletal and muscular reconstruction.)

  13. Fossil Evidence for Language5

  14. Homo neanderthalensis Neanderthals lived between 200,000 and 28,000 years ago in what is now Europe and the Middle East. There is evidence that they may have buried their dead, and that they may have had other religious rituals. (Artists rendition based on skeletal and muscular reconstruction.)
