新的研究将澳大利亚和南美树蛙的差异 推向至少5500万年前。 New study pushes back divergence of Australian and South American tree frogs to at least 55 million years ago.

一项新的研究表明,澳大利亚和南美洲的树木青蛙至少5 500万年前就出现差异,比以前想象的要早得多。 A new study reveals that Australian and South American tree frogs diverged at least 55 million years ago, much earlier than previously believed. 研究人员从大约5500万年前的澳大利亚古树蛙Litoria Tylerantiqua中发现了一个新物种。 Researchers identified a new species of ancient Australian tree frog, Litoria tylerantiqua, from around 55 million years ago. 这一发现基于昆士兰州的化石发现, 表明这些青蛙群落比想象的要老, 挑战其进化分裂的早期时间表。 This discovery, based on fossils found in Queensland, suggests these frog lineages are older than thought, challenging earlier timelines of their evolutionary split.
