摘要

The rapid uplift of the Tibetan Plateau during the late Cenozoic changed it into a habitat island isolated from an increasing complexity of less elevated environments.This makes it a laboratory similar to the Galapagos Islands for studying evolution in action.Inspired by studies on the spatial distribution of Recent schizothoracine fishes on the Tibetan Plateau,we report on evolution of Cenozoic fossil schizothoracines and habitat fragmentation against the backdrop of tectonic uplift.Our results show that the earlier fossil schizothoracines had more rows of pharyngeal teeth and lived at lower altitudes than their relatives from younger deposits.They belong to the primitive grade whose living representatives now live in the peripheral area of the Tibetan Plateau at relatively low altitude.These earlier fossil schizothoracines have been uplifted to the present elevation,and some are in the central area of the Plateau,where they would not have been able to survive were they still alive.Thus,the temporal distribution pattern of the fossil schizothoracines approximately mirrors the spatial distribution pattern of their living counterparts,which reflects the biological responses to the stepwise uplift of the Tibetan Plateau.The consistency in independent lines of evidence between extant and extinct fishes illustrates the beauty of Darwinism.Through ascent with modification,the fossil schizothoracine fishes demonstrate how their own group has adapted to the ever-changing environment caused by geological,biological,and climatic interplays.We also discuss future research prospects provided by the Tibetan Plateau for related disciplines.
