Scientists say molecular ecology may finally give future space missions a clear alien biosignature target instead of only searching for water or organic molecules, future probes could look for ecological patterns that may reveal active extraterrestrial life interacting and evolving.
Scientists may have found a powerful new way to hunt for alien life, Scientists say molecular ecology may finally give future space missions a clear biosignature target instead of just searching for water or organic molecules, missions could look for ecological patterns that strongly suggest life is actively interacting and evolving not by searching for specific molecules, but by looking for hidden patterns in how those molecules are organized. Researchers discovered that living systems leave behind a kind of chemical “fingerprint” in the statistical distribution of amino acids and fatty acids, one that consistently differs from nonliving chemistry.
