They wanted a concerted effort and new approaches to some long-unsolved problems concerning the chemical origins of life.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EBiological evolution deals with changes in living organisms, past and present, while chemical evolution, as defined by the CCE, focuses on uncovering how simple molecules present on the early Earth gave rise to the more complex molecules that eventually allowed for the emergence of life.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EWhen molecules, or chemicals, undergo a reaction, such as in laboratory experiments, it is often the case that a complex mixture of molecules is produced, including the production of many unexpected or undesired molecules. Scientists studying chemical evolution have long sought to understand how biomolecules, like DNA and proteins, then, could have evolved from the complex mixture of molecules present on the prebiotic Earth \u0026mdash; without the aid of a chemist to guide particular reactions or to purify specific products.\u003C\/p\u003E\r\n\r\n\u003Cp\u003ECCE approached this problem by posing a different angle than most other scientists, Hud shares. \u0026ldquo;We came in with the idea that the molecules that are in life today were not necessarily those that started life \u0026mdash; because the molecules that started life may have evolved, they may have been refined by evolution to become what they are today,\u0026rdquo; he explains. \u0026ldquo;An overarching hypothesis of ours was that if we make even small changes to the molecules that are the building block of the biopolymers found in life today, that we might find molecules that form polymers much more easily.\u0026rdquo; Biopolymers are very large molecules, such as DNA, protein, and polysaccharides, that are central to all life on Earth.\u003C\/p\u003E\r\n\r\n\u003Cp\u003ETen years later, Hud says the CCE now has several examples of how such changes can make it much easier to form molecules and polymers very similar to those found in living organisms, but in reactions that are believed to have happen on the early Earth. \u0026ldquo;Now we have several models for the synthesis of molecules that may have facilitated the emergence of life. We\u0026rsquo;ve advanced origins of life science by experimentally testing and refining this hypothesis.\u0026rdquo; Possible applications to the fundamental advances made by CCE chemists include new and more efficient methods for the syntheses of pharmaceutical drugs.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAnd while the CCE is officially sunsetting, the group\u0026rsquo;s work will continue to live on through collaborative projects, and will be soon celebrated by the\u0026nbsp;\u003Ca href=\u0022https:\/\/petitinstitute.gatech.edu\/\u0022\u003EPetit Institute for Bioengineering and Bioscience\u003C\/a\u003E\u0026nbsp;through its annual Suddath Symposium.
