The study published in the International Journal of Astrobiology says how evolutionary theory can be used to support alien predictions and how better can we understand their language.Scientists from the University of Oxford in the UK show that aliens are potentially shaped by the same processes and mechanisms that shaped humans, such as natural selection.
“A fundamental task for astrobiologists (those who study life in the cosmos) is thinking about what extra-terrestrial life might be like,” said Sam Levin, a researcher in Oxford’s Department of Zoology. “But making predictions about aliens is hard. We only have one example of life – life on Earthto extrapolate from.
“Past approaches in the field of astrobiology have been largely mechanistic, taking what we see on Earth, and what we know about chemistry, geology, and physics to make predictions about aliens,” said Levin.
In the new study, researchers gives an alternative approach, which is to use evolutionary theory to make predictions that are independent of Earth’s details.
“This approach is useful, because theoretical predictions will apply to aliens that are silicon based, do not have DNA, and breathe nitrogen, for example,” Levin said.
