Evolution of Language:Neanderthal Speech One clue to the evolution of speech is the descent of the larynx which allows for the articulatory control of air.
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.
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
