“I don’t really have a good answer for you,” Ann Ollila, a geochemist at Los Alamos National Laboratory who published the report on these purple rocks, told reporters.
Biochemists are at a loss as to where the bright purple color could have come from. An accurate chemical analysis of these stones will make it possible to understand how the evolution of the planet took place. There is speculation that the mysterious coloration may be evidence of the existence of life on Mars in the past. Proponents of this theory cite the Earth as an example, where living organisms have repeatedly created colored coatings on stones.
