One of the biggest challenges in molecular evolution studies is to gain informations about the evolution of protein tertiary structures. When we try to determine the evolutionary origins of proteins, we basically consider the structure similarities between contemporary proteins, since we don't generally have enough paleo- materials to analyze. Therefore, we can only abstract a … Continue reading Four billion years old protein 3D structure determined by an Euro- American team. Showing the potential of evolutionary research.
