Bolivian archaeologists search for ancient DNA in mummies
2010-02-04 09:11 BJT


Archaeologists at the Tiwanaku ruins in western Bolivia are searching for ancient DNA in mummies. The effort is part of a five-year global project to better understand how human beings migrated from Africa to every corner of the planet.

The Geno-graphic Project will collect more than 100-thousand DNA samples from mummies and indigenous people around the world. It was launched in April 2005, and aims to trace how humans migrated from Africa to nearly every corner of the globe.

Five years on, the project is coming to an end. And the samples from these mummies are some of the last to be collected.

Samples have been taken from twelve archaeological sites in Bolivia over the last six months.

They'll be sent for analysis at a laboratory in Australia, then compared with DNA samples from living Aymara and Quecha people two of the major indigenous groups in Bolivia.

Experts say the analysis to be conducted in Australia will assist researchers in gaining clues from often incomplete DNA samples.

Guideo Valverde, Investigator, San Andreas University, said, "One of the characteristics of this ancient DNA is that it is fragmented, meaning that the DNA chains are not well conserved. The analysis and techniques used by the lab (in Australia) will permit us to reconstruct the DNA that is isolated in the specimens."

The Tiwanaku civilization spread throughout southwestern Bolivia and parts of neighboring Peru, Argentina and Chile from around 1500 BC to 1200 AD.

Its capital was the city of Tiwanaku, which at its peak stretched over 1,480 acres and had a population of over 100,000. It was one of the precursors of the Inca empire, the largest pre-Columbian civilization in the Americas.
