How Language Began
Abstract:
This talk lays out the hypothesis further developed and supported in my 2017
book, How Language Began, that language is a technology/tool that began 1.9
million years ago, emerging from Homo erectus culture. I distinguish language
from communication by the following:
- Communication is the transfer of information.
- Language is the transfer of information via symbols.
In the talk I offer several sources of evidence for the thesis that erectus had
language: tools, cultural organization of villages, travel, physiology,
evolution of the erectus larynx, evolution of the erectus brain, and sailing
voyages, among others. I make the case that the evolution of language followed a
Peircean progression, visible in the archaeological record. All animals use
indexes. The first clear example of an icon is the Makapansgat pebble, collected
by Austrolopithecus africanus roughly three million years ago. Finally, we see
evidence one million years after the first record of an icon for the use of
symbols by erectus. Interestingly, this follows the independently developed
principles of semiotics of C.S. Peirce. Although erectus had a more primitive
vocal apparatus, smaller brains, and less developed form of the FOXP2 gene found
in sapiens, they were nevertheless completely capable of full language. I also
argue for the existence of three types of grammars: G1 (linear), G2
(hierarchical), and G3 (recursive).
