Microevolution of the Chibcha-speaking peoples of Lower Central America: rare genes in an Amerindian complex
(1992)
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 ...

(2018-01-01)
Astyanax anai, a new species of characid fish, is described from the Sixaola River basin, eastern Costa Rica–western Panama, Central America. The new species can be distinguished from all other congeners by the following ...
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
(1990)
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 ...
