A linguist's view of the Bellman-Goldberg thesis

From a linguistic perspective, the Bellman-Goldberg thesis of a necessary relationship between the abilities of organisms to move and communicate is very interesting. Since several concepts and terms are represented in both the thesis and contemporary linguistic literature, these items are discussed in further detail. Questions of the implicit assumptions of the homology of the motor and linguistic systems are also raised here. Finally, there are requests for further clarification on issues of evolution in this test of the strength of the thesis.
