An Agnostic Biosignature for Population-Scale Life Propagation Across Planets via Panspermia and Terraformation
To the point
Harrison B. Smith and Lana Sinapayen propose an agnostic biosignature that looks for population-scale signals of life spreading through the galaxy by panspermia and terraformation, using clustering of planets by observable traits and an objective function to select the nearest planet whose composition matches the parent for studying a terraformed lineage.
