High up in the high Andes mountains of Argentina, researchers have identified the first-ever evidence of a population uniquely adapted to
tolerate the toxic chemical arsenic.
For thousands of years, in some regions of the Andes, people have
been exposed to high levels of arsenic, a naturally occurring phenomenon
that happens when arsenic in the volcanic bedrock is released into the
groundwater. How could this population adapt to tolerate arsenic, a
potent killer of such ill repute that it’s often the overused
plot-driver of many murder mysteries?
