麻省理工研究:地球上最早的动物很可能是古海绵
麻省理工科学家发现,地球上最早的动物很可能是古海绵。科学家在541万年前的岩石中发现了罕见的分子“指纹”,这些指纹与现代海绵产生的化合物相匹配。通过测试岩石、活海绵和实验室合成的分子,研究人员确认这些信号来自生命,而不是地质过程。…

ScienceDaily MIT study finds Earth’s first animals were likely ancient sea sponges Scientists at MIT have found compelling chemical evidence that Earth’s earliest animals were likely ancient sea sponges. Hidden inside rocks over 541 million years old are rare molecular “fingerprints” that match compounds made by modern demosponges. After…
