地球上许多细胞生命体的一个关键特征是硬质的生物结构,例如由矿物质构成的动物骨骼和蜗牛壳。最近,研究人员在加拿大发现了微体化石。这一发现不仅将迄今最古老的生物矿化证据追溯至8.1亿年前,还有助于在其他行星上定位查找化石,研究生命体和行星随时间推移共同演化的方式。研究人员在《科学进展》杂志上详细介绍了该发现。他们获得了美国航空航天局天体 A key feature of many cellular organisms on Earth is their hard biological structures, such as animal bones and snail shells made of minerals. Recently, researchers discovered microfossils in Canada. This discovery not only traces the oldest biological mineralization evidence to date to 810 million years ago, but also helps locate and locate fossils on other planets and studies how life bodies and planets co-evolve over time. The researchers described the findings in detail in Progress in Science. They got NASA astronomers
