Uncovering the Ancient Bacteria Species That First Colonized Our Planet
A new study published in the journal Nature has revealed that an ancient species of bacteria called Parcubacteria may be the earliest known form of life on Earth. The bacteria have been found in rocks that are over 3.5 billion years old, which suggests that they may have been among the first organisms to colonize the planet. The discovery of the Parcubacteria is important because it gives us insight into the evolution of life on Earth and may help us understand how and why life emerged on our planet.
