The earliest life on Earth might have been just as purple as it is green today, a scientist claims.
Ancient microbes might have used a molecule other than chlorophyll to harness the Sun’s rays, one that gave the organisms a violet hue.
Primitive microbes that used retinal to harness the sun’s energy might have dominated early Earth, DasSarma said, thus tinting some of the first biological hot-spots on the planet a distinctive purple color.
The researchers speculate that chlorophyll- and retinal-based organisms coexisted for a time.
“You can imagine a situation where photosynthesis is going on just beneath a layer of purple membrane-containing organisms,” DasSarma told LiveScience.
But after a while, the researchers say, the balance tipped in favor of chlorophyll because it is more efficient than retinal.
