It has been the missing link between chemistry and biology in the origin of life.” “However, the origin of molecular assemblies that proliferate from small molecules has remained a mystery for about a hundred years since the advent of the chemical evolution scenario.
“Since then, many studies have been conducted to verify the RNA world hypothesis - where only self-replicating genetic material existed prior to the evolution of DNA and proteins - experimentally,” Matsuo continues. “Chemical evolution was first proposed in the 1920s as the idea that life first originated with the formation of macromolecules from simple small molecules, and those macromolecules formed molecular assemblies that could proliferate,” says the study’s first author, Muneyuki Matsuo, an assistant professor of chemistry in the Graduate School of Integrated Sciences for Life at Hiroshima University, in a statement. Known as a “coacervate droplet,” it depicts the transition from chemistry to life. Two Japanese scientists created a microscopic particle capable of replicating itself. But the question is, how did the first living organism come to be? This gap between chemical evolution and the beginning of biological evolution may be a little smaller according to recent findings.
Genetic sequencing and the geologic column have enabled biologists to produce the phylogenetic tree, spanning from the most complex organisms all the way down to the simplest, single-celled lifeform that gave rise to all living things. HIROSHIMA, Japan - For many years, scientists have studied the biological evolutionary theory.
