Chemical Evolution
Chemical evolution refers to the gradual process of chemical changes that occurred in the early universe, leading to the formation of the first stars, galaxies, and eventually life on Earth. It involves the formation of chemical elements through nuclear fusion in stars, the distribution of these elements through space by supernova explosions, and the formation of planets and other celestial bodies from the leftover materials. Chemical evolution also encompasses the study of the chemical reactions that occurred on early Earth, leading to the formation of organic molecules and the emergence of life. This field of study is important for understanding the origins of life and the evolution of the universe.
