我们讨论了新喀里多尼亚的动物群的背景下，格兰德特雷的长期淹没，直到其重新出现约3 700万年前，以及所产生的动物群是否可以完全解释为水上传播。目前的文献讨论占主导地位的新特有种在新喀里多尼亚进行审查，质疑一些话语的事实，即大多数动物和植物谱系是新特有种应权衡忽视的情况下，古特有种（分支，坚持和多样化在新喀里多尼亚超过37万年）。我们认为，在文献中使用的许多例子，选择用于其他目的，没有选择来测试这个特定的假设，但几个古老的血统的非流浪动物表明，一个不平凡的数量的分支有一个历史，早于假定的新喀里多尼亚的出现。最后，我们提出的问题，应该需要多少额外的证据来证明群岛的地质历史和其生物群的进化历史之间的不一致。
We discuss the fauna of New Caledonia in the context of the prolonged submergence of Grande Terre until its re-emergence around 37 million years ago and whether the resulting fauna can be entirely explained by over-water dispersal. The current literature discussing the predominant neoendemism in New Caledonia is reviewed, questioning some of the discourse about how the fact that most animal and plant lineages are neoendemics should weigh in to disregard the fewer cases of paleoendemism (clades that have persisted and diversified in New Caledonia for over 37 million years). We argue that many of the examples used in the literature, selected for other purposes, were not chosen to test this particular hypothesis, but several old lineages of non-vagile animals show that a non-trivial number of clades have a history that predates the supposed emergence of New Caledonia. We conclude by posing the question of how much additional evidence should be needed to demonstrate a discordance between the geological history of the archipelago and the evolutionary history of its biota.
