渐变论 meaning in English

gradualism

The dispute is between the gradualists and those who think that the sudden shifts in fossil types seen in the geological record are real , rather than a consequence of the irregular way that rocks are laid down
争论的双方分别是渐变论者和突变论者（认为地质记录中所见的化石类型骤变是一种真实的现象，而不是岩石的不规则排列所造成的结果）。
But , in a similar way to dr jablonski ' s study , which suggests that models of cradles and museums present a false dichotomy , a paper from a member of the gradualist camp of time biology endorses some features of jerky evolution
但是，正如捷布朗斯基博士的研究表明将源、汇模型对立起来是错误的一样，一篇出自时间生物学领域里渐变论阵营中某个成员的论文同样地支持某些跳跃式进化的特性。
