Chromosomal breakage in leukocytes of South American Indians

Cytogenetics and Cell Genetics, 2008
Cytogenetic studies were performed in 1969, 1970, and 1971 on the Yanomama and Piaroa Indians of Venezuela. The early studies involved 49 Yanomama, of whom 13 had 23 cells with extensive chromosome breakage and rearrangement, so-called complex cells. The virtual disappearance of these complex cells in subsequent studies of the Yanomama was accompanied ...

1969
At the end of the Pleistocene period, more than ten thousand years ago, nomadic hunters and food gatherers from North America penetrated into South America and rapidly pushed forward to the southern tip, probably following the same route which was later taken by the Incas and which is followed by the Pan-American Highway today.

North and South American Indian Music

The Journal of American Folklore, 1967
as a nonspecialist, I am impressed by the competence of this group. A third point of interest is much more academic, but it is one which should be food for thought for folklorists concerned with the "folksong revival" and with other sorts of transfer of folklore from a rural habitat to a foreign or urban culture.

On South American Indian languages: reply to Aikhenvald

Journal of Linguistics, 2003
My aim here is to clarify some misinterpretations in Aikhenvald's (2002) review of my book (Campbell 1997). It is an unusual review, written four years after the book appeared, and not so much a book review as a critique of one chapter, on South American languages; even here it concentrates only on languages of Amazonia.

South and Central American Indian Languages

1977
Data from numerous maps have been consolidated for the maps in the present volume. The major contributions, however, have been those of Swanton for North America and the wall map of Loukotka for South America. It is hoped that the maps in the present volume will be found useful in spite of the deficiencies which plague attempts to include a great range

Esterase D in South American Indians.

American journal of human genetics, 1976
Significant variation in the frequency of Esterase D isoenzymes was found in 1,070 individuals belonging to eight South American Indian tribes. The Es D1 allele shows frequencies varying from .36 to 1. A region of low prevalence of this allele seems to exist in northern Brazil, involving the Parakanan, Gorotire, and Krahó.
