- The extreme climate arisen from "snowball Earth" may promote evolution of life and trigger the "Cambrian Explosion". "雪球地球"的极端气候环境变化,促进了生命的演化,造成了寒武纪生物大爆发。
- This event is sometimes called the "Cambrian Explosion", because of the relatively short time over which this diversity of forms appears. 这次事件有时称"寒武纪爆炸",由于形式这变化看上去的相对地短时间。
- If I can engineer a world to the threshold of the Cambrian explosion and let it boil over the edge on its own, that will be truly impressive. 如果我可以操控一个世界达到寒武纪大爆发的临界点,然后让它自己沸腾溢出边界,那才是真正的永生难忘。
- Recent research suggests that the period prior to the Cambrian explosion saw the gradual evolution of a "genetic tool kit" of genes that govern developmental processes. 最近研究建议,期间在寒武纪爆炸之前看了"基因工具箱的逐渐演变治理发展过程的"基因。
- These new materials provide new evidence for the origin, evolution and the functional evolution of the metazoan during the early stage of the Cambrian explosion. 本文报道的奇异星状生物可能代表了初具原始触手的腔肠动物早期演化类型,为研究真后生动物起源演化、能进化提供了新的实证材料。
- For a long time, it has become a common belief that in Cambrian there must have been some miraculous life explosion, which is “Cambrian Explosion” so called by geologist. 长期以来,人们普遍相信寒武纪一定发生了什么奇迹性的生命爆发事件。也就是地质学家们所说的“寒武纪大爆发”。
- The Middle Cambrian Burgess Shale, discovered at the early of the last century, has long been considered as one of the best windows on the Cambrian explosion. 中寒武世布尔吉斯页岩发现早、研究历史长,是早期人们认识寒武纪爆发规模的较理想的窗口。
- A lagerst?tte older than the Burgess Shale, in the Chengjiang area of China's Yunnan Province, has yielded many important recent finds of soft-bodied organisms also characteristic of the Cambrian explosion. 在中国云南的澄江一带,有著比伯吉斯页岩更古老的特异埋藏点,已发掘出许多同样具有寒武纪大爆发特色的重要软体生物。
- This investigation placed the last common ancestor of bilaterian animals at a much younger date, though still older than the Cambrian explosion, somewhere between 573 million and 656 million years ago. 这项研究把两侧对称动物最后的共同祖先,定置于较晚的时间,不过仍比寒武纪大爆发的时间要早,大约是6亿5600万年至5亿7300万年前之间。
- So while there are points in evolution where results are sensitive to initial conditions (the birth of the Cambrian explosion could be one) this by no means rules out the influences of large trends. 所以,虽然进化的观点认为结果对于初始条件是非常敏感的(寒武纪生命大爆发就是其一),但是这绝不可能排除大趋势的影响。
- And then something wild starts to happen: a dazzling diversification of life into multi-celled forms during a geologically brief time period that scientists call the Cambrian Explosion. 接着便有不可思议的事情发生了,在科学家称作“寒武纪爆发”的短暂地质时期内,生命具有了令人目眩的多样化,进入了多细胞形态。
- Cambrian and the Cambrian Explosion 三寒武纪及寒武纪大爆发
- STRANGELOVE OCEAN BEFORE THE CAMBRIAN EXPLOSION 寒武纪生物爆发前的死劫难海洋
- The explosion toppled the near chimney. 这次爆炸把不远处的烟筒炸倒了。
- Whatever the cause, there was one big difference between the Avalon and Cambrian explosions: The Cambrian produced groups that endure to this day, Xiao says, whereas the Ediacaran forms soon vanished. 不过,无论原因为何,阿瓦隆纪大爆发和寒武纪大爆发之间存在着一个最大不同,即寒武纪出现的生物种类持续至今,而埃迪卡拉纪物种形式很快就消失了。
