Life in space by Levin, S

“…(vii) Finally, I consider the universality of natural selection and major transitions in individuality, demonstrating how evolutionary theory can be used as a powerful tool in astrobiology. As a whole, this body of work extends the range of inclusive fitness theory’s application earlier in evolutionary time, to a wider range of biological scenarios, and further in space. …”
