Today, when you look around the Earth, you see a lot of green. It is easy to imagine that things were the same before humans or even dinosaurs roamed the Earth, but if you go back far enough, you will find a life that does not have much of a life. interest in the color green. New research has revealed what is believed to be the oldest known pigment created by a living creature … and pink
Scientists from the Australian National University were studying ancient marine schists – a type of rock formed of mud or sediment – when they discovered what appears to be the remains of some seriously old bacteria. The researchers milled the shale and were able to isolate the pigment that was present in the bacteria, noting that it shines bright pink when exposed to sunlight

We surprisingly know little about what the Earth could have been a billion (or more) years ago. The remains of complex life forms do not appear in the fossil record until hundreds of millions of years later, and the soft-bodied organisms that evolved in the ocean have not tendency to produce good fossils. Studies like this give us a rare glimpse of the distant past, and now we know that the past was rosy.
