Microevolution in lower Central America: Genetic characterization of the Chibcha-speaking groups of Costa Rica and Panama, and a consensus taxonomy based on genetic and linguistic affinity
There is evidence that Amerindians have continuously occupied the lower Central American Isthmus for as long as 10,000 years. There remains some doubt about the relationships of these original colonizers to the resident ...
Mitochondrial DNA “clock” for the Amerinds and its implications for timing their entry into North America
Students of the time of entry of the ancestors of the Amerinds into the New World are divided into two camps, one favoring an "early" entry [more than approximately 30,000 years before the present (YBP)], the other favoring ...
Microevolution of the Chibcha-speaking peoples of Lower Central America: rare genes in an Amerindian complex
Models are developed for the survival, history, and spread of variant alleles, in order to consider what can, and what cannot, be inferred from this type of data. The high variances of the processes involved, and questions ...
Migration and Genetic Infrastructure of the Central American Guaymi and Their Affinities With Other Tribal Groups
(American Journal of Phisical Antropology: 58 p.201-214, 1982-06)
New genetic data on 40 red cell enzymes, antigenic blood groups, and serum proteins representing 42 separate loci, are reported for two Guaymi communities in Southeastern Costa Rica. These two settlements, Limoncito and ...
