Abstract

Determining whether a planet can harbor life remains a fundamental question in science and society. In this study, we leverage network theory to explore the distinctive patterns exhibited by minerals and their mineralizing environments in biotic and abiotic contexts. The examination of mineralogical networks in diverse planetary contexts enriches our understanding of Earth's history and provides a platform to investigate the factors that influenced the development and sustainability of life on our planet. Our investigation spans a wide range of systems, from the earliest solar system bodies to the early Hadean Earth, plate tectonics, and modern Earth. By analyzing the mineralogical relationships within biotic and abiotic settings, we reveal compelling evidence supporting the existence of distinct characteristics within biotic networks that set them apart from their abiotic counterparts.

This research advances our comprehension of the complex and evolving interplay between Earth and life. Network analysis provides deeper insights into the underlying mechanisms governing the connections between minerals and living systems, offering invaluable perspectives on the emergence and co-evolution of life on our planet. Moreover, our findings contribute to the identification and characterization of planetary biosignatures, crucial for the exploration for extraterrestrial life. The recognition of unique patterns within biotic networks lays the foundation for the development of targeted exploration strategies for extraterrestrial life. As we endeavor to identify signs of life beyond our planet, comprehending the distinctive characteristics of biotic mineralogical networks enhances our capacity to detect potential biosignatures and interpret the complexities of planetary environments.

In conclusion, our network analysis of minerals and mineralizing environments presents a novel and powerful approach to investigating the relationships between Earth and life. By probing the intricate interconnections within biotic and abiotic systems, we gain a deeper appreciation of our planet's dynamic history and advance our knowledge of potential habitats for life beyond Earth.
