Hominin evolution in the African Pliocene and Pleistocene was accompanied and mediated by changes in the abiotic and biotic spheres. It has been hypothesized that such environmental changes were catalysts of hominin morphological evolution and speciations. Whereas there is little doubt that ecological changes were relevant to shaping the trajectories of mammalian evolution, testing specific hypotheses with data from the fossil record has yielded ambiguous results regarding environmental disruption as a primary catalyst. Proposed mechanisms for abiotic and biotic causes of evolution are not always consistent with the timing and trends exhibited by the African fossil record of hominins and other mammals. Analyses of fossil and genetic data suggest that much of hominin evolution, and by extension mammalian evolution, was autocatalytic, driven by feedback loops within a species or lineage, irrespective of changes in the external environment.

与非洲人源蛋白进化的相关性和催化剂。
非洲上新世和更新世的人红素进化伴随着非生物和生物领域的变化并由其介导。据推测,这样的环境变化是人均形态演化和物种形成的催化剂。尽管毫无疑问,生态变化与塑造哺乳动物进化的轨迹有关,但是用化石记录的数据检验特定的假设已经产生了关于环境破坏作为主要催化剂的模棱两可的结果。非生物和生物进化原因的拟议机制并不总是与人类化石和其他哺乳动物的化石记录所显示的时间和趋势一致。对化石和遗传数据的分析表明,大多数人源素的进化以及哺乳动物的进化都是自催化的,
