Title: Evolution of Language: Neanderthal Speech


1
Evolution of LanguageNeanderthal Speech
  • One clue to the evolution of speech is the
    descent of the larynx which allows for the
    articulatory control of air.

2
Arch of Cranial Base Indicates descended larynx
  • Earliest hominins (Australopiths) had cranial
    base similar to apes
  • Cranial base approximates human angle in Kabwe
    and Steinheim skulls (around 300,000 ybp)
  • Neanderthal cranium actually flatter than some
    older samples.

3
Hominin Evolutionary Chronology
  • 5-7 mybp split between chimp and hominin lines
  • 5-4 mybp emergence of earliest hominins
    australopiths
  • 2.5-2 mybp emergence of genus Homo (first major
    brain size expansion
  • 1.8 mybp emergence of Homo erectus/ergaster
    (first evidence of human-like traits)
  • .5 mypb emergence of Homo heidelbergensis (first
    of the archaic Homo sapiens second major
    expansion in brain size
  • 200,000 ybp emergence of Homo sapiens,
    Neanderthals
  • 35,000 ypb Upper Paleolithic revolution

Animal Language Vervet Alarm Calls
  • Different alarm calls appear to be referential

5

  • Washoe Koko Nim Chimpsky
  • Fouts/Gardners Francine Patterson Herb Terrace

  • Lexigram symbol language
  • Simple syntax
  • Spontaneous acquisition
  • Referential/symbolic understanding
  • 90 utterances requests/commands

  • Two steps protolanguage associated with
    increasing brain size
  • Full language associated with cultural
    revolution in UP
