That means that alien life could be using the same strategy. Regardless of whether the first life on Earth was purple, it's clear that lavender life suits some organisms just fine, Schwieterman and DasSarma argue in their new paper. There is even some evidence that modern purple-pigmented salt-loving organisms called halophiles might be related to some of the earliest life on Earth, which thrived around methane vents in the ocean, Schwieterman said. The appearance of the pigments across many living organisms hints that they may have evolved very early on, in ancestors common to many branches of the tree of life, the researchers wrote. Retinal pigments are also found in the visual system of more complex animals. These purple organisms have been discovered everywhere from the oceans to the Antarctic Dry Valley to the surfaces of leaves, Schwieterman told Live Science. ![]() Retinal light-harvesting is still widespread today among bacteria and the single-celled organisms called Archaea. They're not as efficient as chlorophylls in capturing solar energy, but they are simpler, the researchers wrote in their new paper published Oct. Retinal pigments absorb green light best.
