The evolution of life on Earth has always been a subject of fascination for scientists. From the emergence of single-celled organisms to the complex web of biodiversity we see today, the origins and mechanisms of evolution have been a matter of intense study. Now, a groundbreaking research paper published in Proceedings of the National Academy of Sciences has proposed a new evolutionary law that sheds light on the interplay between living and non-living entities, specifically minerals and biological organisms.
According to this study, natural systems, whether living or non-living, tend to evolve towards states of greater complexity, diversity, and patterning. As life on Earth evolved from simple single-celled organisms to more complex multi-cellular forms, minerals also underwent a transformation, becoming more intricate and diverse in the process. The researchers argue that this increase in mineral diversity played a crucial role in driving biological evolution.
The concept of biodiversity leading to mineral diversity, and vice versa, highlights the intricate connection between the two systems. Both biological and mineral systems interacted and shaped each other, ultimately leading to the rich tapestry of life we observe today.
What sets this research apart is the collaboration between scientists and philosophers of science. By combining the empirical and theoretical perspectives, the team behind this study aimed to develop a comprehensive theory that explains the bewildering complexity and diversity of the natural world.
The key insight provided by the research is that evolution occurs when new configurations or arrangements of atoms and molecules facilitate improved functionality. While Darwin famously defined function in terms of survival, this study identifies three fundamental types of functions: stability, dynamic energy systems, and novelty.
Stability refers to systems characterized by stable arrangements of atoms or molecules that can persist over time. Dynamic energy systems require a continuous supply of energy to sustain their functionality. The concept of novelty revolves around evolving systems exploring new configurations or arrangements, which can give rise to new behaviors or characteristics.
By applying these principles to the early Earth, the researchers demonstrate how minerals with stable atomic arrangements served as the foundation for subsequent generations of minerals. These minerals then became incorporated into living organisms, such as shells, teeth, and bones.
In the early years of the Solar System, Earth was home to a mere 20 minerals. However, over billions of years and through intricate physical, chemical, and biological processes, the number of known minerals has expanded to nearly 6,000.
A similar pattern emerges when looking at the evolution of stars. The early stars of the universe consisted primarily of hydrogen and helium. Yet, through nuclear fusion, these stars produced heavier chemical elements. Subsequent generations of stars further enriched the galaxy with new elements.
According to Michael L Wong, the lead author of the study, the key to evolution lies in the generation of novel combinations of atoms, molecules, and cells. Systems that achieve stability while also fostering further novelty continue to evolve.
This groundbreaking research has far-reaching implications for various domains of science, from astrophysics to ecology to artificial intelligence. It opens up new avenues for collaboration among scientists, as they work together to uncover the underlying principles of evolution in different fields.
