Parallels between genetic and language evolution have been noticed since Charles Darwin [3] and, although there is still some debate, it is generally accepted that language has evolved and diversified obeying mechanisms similar to those of biological evolution [4].
This further suggests possible links between toolmaking and language evolution.
Such observations have led various researchers to consider possible links between stone toolmaking and language evolution [e.g. 11], [14], [15].
Stout calls the new study "exciting work" that provides "one more piece of evidence supporting a link between stone-tool making and language evolution".
This question is central to the debate regarding the similarities and differences between nonhuman animal (hereafter animal) communication and human language, and consequently, language evolution.
Just like genes, words change over time, and language evolution can be likened to genome evolution accordingly, but what kind of evolution?
This language evolution may weaken the interface between design and implementation, introducing what we call 'design dysphasia' a partial disability in the use of a programming language because of incongruous design methods.
Dr. Daniel Geschwind, a professor of human genetics, neurology and psychiatry at University of California, Los Angeles, School of Medicine, is interested in the connections between language and handedness, and the ways that handedness can help us understand the evolution of the human brain.
A few swipes of a cloth, and many centuries of Northern European language evolution disappeared.
Further research into chimpanzee vocal behaviour may provide more evidence for continuity between elements of monkey and human vocal communication with considerable relevance for theories of language evolution.
