The degree of gradualism with which tertiary structure and function of protein changes with stepwise changes in primary structure (assumed to be influenced by redundancy of weak bonding) is both a precondition for and consequence of evolution. The resulting selection for degree of gradualism has implications for a number of structural and functional properties of modern proteins as well as for the significance of neutral (so-called non-Darwinian) phenomena in relation to selection.
蛋白质的三级结构和功能随一级结构的逐步变化(假定受弱键冗余影响)而渐变的程度,既是进化的前提条件,也是进化的结果。由此产生的对渐变程度的选择,对现代蛋白质的许多结构和功能特性,以及对中性(所谓非达尔文式)现象与选择相关的意义都有影响。
