Abstract

The survival of ancient DNA in specimens up to several thousands of years old is established. However, there have been several claims concerning the recovery of geologically ancient DNA from fossil material many millions of years old. The authenticity of these fossil DNA sequences is questionable on theoretical and empirical grounds, and the existence of authentic geologically ancient DNA remains to be proven.

摘要

古 DNA 在几千年历史的标本中得以存活已被证实。然而，有一些声称从数百万年前的化石材料中回收了地质古老的 DNA。这些化石 DNA 序列的真实性在理论和经验上都存在疑问，而且真正的地质古老 DNA 的存在仍有待证明。
