New evolutionary law

October 22 , 2023 272 days 299 0
  • Scientists have proposed a new evolutionary law that can explain the evolution of living and non-living entities, from minerals to stars.
  • As life evolved from single-celled to multi-celled organisms, Earth’s minerals, for example, became more complex, creating diversity.
  • This, in turn, drove biological evolution.
  • Biodiversity leads to mineral diversity and vice-versa.
  • The two systems, biological and mineral, interacted to create life as we know it today.
  • Evolution occurs when a new configuration or a new arrangement of atoms and molecules works well and functions improve.
  • Darwin defined function as primarily with survival.
  • But the new study highlights at least three kinds of functions that occur in nature.
  • The first function is stability, which means systems made up of stable arrangements of atoms or molecules will continue to survive.
  • The second one includes dynamic systems with energy supply.
  • The third is “novelty” — the tendency of evolving systems to explore new configurations or arrangements that can give rise to new behaviours or characteristics.
