The urge to understand alien life is something that has long fascinated scientists. Many processes have been applied by scientists when it comes to understanding the workings of different planetary environments and it seems that the study of micro-organisms may be the answer to their questions. According to the latest research, microbes contain proteins that are able to retain atmospheric information for long periods of time and were used by scientists to understand how the Earth was in its early days. Microorganisms date back millions of years and scientists believe a similar study could help them find possible traces of alien life.
“Early Earth is an alien environment compared to today’s world. Understanding how the organisms here have changed over time and in different environments is going to teach us important things about how life is discovered and lived elsewhere. be identified,” said Edward Schwieterman, University of California, Riverside astrobiologist, in a study about the research and its potential uses.
The study looked at how microbes adapted to the lack of oxygen as well as the absence of the ozone layer during that period and could be used to find other habitable planets.
“On the early Earth, energy may have been very scarce. Bacteria and archaea figured out how to harness energy from the Sun without the complex biomolecules needed for photosynthesis.”
“Life as we know it is as much a manifestation of the conditions on our planet as it is of life itself. We revived the ancient DNA sequences of a single molecule, and this allowed us to link it to the biology and environment of the past. Granted,” said University of Wisconsin-Madison astronomer Betul Kakar.
