O'Dea . challenged the inference that the Isthmus of Panama has been in place for the last 10 million years or more and from "an exhaustive review and reanalysis of geological, paleontological, and molecular records," they argued for a "formation of the Isthmus of Panama sensu stricto around 2.8 Ma." I review environmental changes since ~5 Ma throughout Earth, and I argue that environmental changes in the Central American-Caribbean region have been part of a concurrent, worldwide phenomenon that requires a global, not local, explanation. Accordingly, evidence of environmental change from the Central American-Caribbean region does not implicate the emergence of the Isthmus of Panama.
奥黛(O'Dea)质疑巴拿马地峡在过去 1000 万年或更长时间内一直存在的推断,并从“对地质、古生物学和分子记录的详尽回顾和重新分析”中,他们提出了“巴拿马地峡 sensu stricto 的形成大约在 280 万年前。”我回顾了自约 500 万年前以来地球各地的环境变化,并认为中美洲-加勒比地区的环境变化是同时发生的全球现象的一部分,需要全球而不是局部的解释。因此,从中美洲-加勒比地区获得的环境变化证据并不暗示巴拿马地峡的出现。
