People have inhabited the Andes mountains of South America for more than 9,000 years, adapting to the scarce oxygen available at high altitudes, along with cold temperatures and intense ultraviolet radiation. A new genomic study published in the journal iScience suggests that Indigenous populations in present-day Ecuador also adapted to the tuberculosis bacterium, thousands of years before the arrival of Europeans...
"We found that selection for genes involved in TB-response pathways started to uptick a little over 3,000 years ago," says Sophie Joseph, first author of the paper. "That's an interesting time because it was when agriculture began proliferating in the region. The development of agriculture leads to more densely populated societies that are better at spreading a respiratory pathogen like TB."
The investigators had originally set out to investigate how the Indigenous people of Ecuador adapted to living at high altitude.
"We were surprised to find that the strongest genetic signals of positive selection were not associated with high altitude but for the immune response to tuberculosis," says John Lindo, senior author of the study. "Our results bring up more questions regarding the prevalence of tuberculosis in the Andes prior to European contact."
Previously published research found evidence of the tuberculosis bacterium in the skeletal material of 1,400-year-old Andean mummies, contradicting some theories that TB did not exist in South America until the arrival of Europeans 500 years ago.
