The genetic information for this work came from a very large collection of gene frequencies for 'classical' (non-DNA) polymorphisms of the world aborigines. The data were grouped in 42 populations studied for 120 alleles. The reconstruction of human evolutionary history thus generated was checked with statistical techniques such as 'boot-strapping'. It changes some earlier conclusions and is in agreement with more recent ones, including published and unpublished DNA-marker results. The first split in the phylogenetic tree separates Africans from non-Africans, and the second separates two major clusters, one corresponding to Caucasoids, East Asians, Arctic populations, and American natives, and the other to Southeast Asians (mainland and insular), Pacific islanders, and New Guineans and Australians. Average genetic distances between the most important clusters are proportional to archaeological separation times. Linguistic families correspond to groups of populations with very few, easily understood overlaps, and their origin can be given a time frame. Linguistic superfamilies show remarkable correspondence with the two major clusters, indicating considerable parallelism between genetic and linguistic evolution. The latest step in language development may have been an important factor determining the rapid expansion that followed the appearance of modern humans and the demise of Neanderthals.
Self Organizing System Obtaining Communication Ability - A Primitive Model for Language Generation
Biological Cybernetics 58:417-425, 1988
As one of the synthetic approaches to brain functions, the possibility is discussed that two intellectual robots could make “words” for themselves and come to communicate with each other. Associatron, a model for associative memory with a neural network structure, is ...

Morphology as lexical organization
Theoretical morphology, pages 119-141, 1988
Most current conceptions of the apparatus behind linguistic behavior postulate separate components for rules and representations. Representations are static and fixed, the individual and idiosyncratic content of the morphology, while the rules are the" moving ...
