  The Americas were the last continents reached by modern humans, most likely through Beringia. However, the precise time and mode of the colonization of the New World remain hotly disputed issues.
  Native American populations exhibit almost exclusively five mitochondrial DNA (mtDNA) haplogroups (A-D and X). Haplogroups A-D are also frequent in Asia, suggesting a northeastern Asian origin of these lineages.
  However, the differential pattern of distribution and frequency of haplogroup X led (...)

  Mitochondrial and Y-chromosome DNA were analyzed from 10,300-year-old human remains excavated from On Your Knees Cave on Prince of Wales Island, Alaska (Site 49-PET-408).
  This individual’s mitochondrial DNA (mtDNA) represents the founder haplotype of an additional subhaplogroup of haplogroup D that was brought to the Americas, demonstrating that widely held assumptions about the genetic composition of the earliest Americans are incorrect.
  The amount of diversity that has accumulated in the (...)

  Data demonstrate the existence of a shared maternal genetic structure between Central American Chibchan, Mayan populations and northern South American Chibchan-speakers.
  It has been suggested an expansion of Chibchan-speakers into South America associated with a shift in subsistence strategies because of changing ecological conditions that occurred in the region between 10,000-14,000 years before present.

• Cayapa
  28 September 2005

  The Cayapa are an Ecuadorian Amerindian tribe belonging to the Chibcha-Paezan linguistic branch.
  Three major maternal lineage clusters fit into the Haplogroup A, Haplogroup B, and Haplogroup C.
  A fourth lineage, apparently unique to the Cayapa, has ambiguous affinity to known clusters.
  The time of divergence from a common maternal ancestor of the four lineage groups is of sufficient age that it indicates an origin in Asia and supports the hypothesis that the degree of variability (...)
