One of the biggest difficulties of defining technosignatures is to think
about how to accurately distinguish biosignatures and technosignatures.
In order to distinguish them, we need to further advance our
understanding of what biology and technology are fundamentally doing. In
this work, we introduce big data approaches to statistically investigate
universal patterns within all biological life on Earth. We measure
chemical complexity produced by life and investigate how universal or
different biology is. Revealing universality of biology can help clarify
the properties unique to biological life and help distinguish
technosignatures from biosignatures.
