摘要
破解"寒武纪生命大爆发"之谜,仍有若干困惑值得思考,一是三十多个不同门类的动物何以在寒武纪同时出现?二是还没有发现任何证据表明寒武纪三十八门同时出现的生物是从瓮安动物渐变进化而来,那么,谁是寒武纪三十多个不同门类动物的共同祖先?三是寒武纪以来不同门类的动物进化速率何以如此悬殊?四是寒武纪原始脊椎动物何以出现几乎没有任何价值的原脊椎?
Resolving the mystery on the 'Cambrian explosion of life',there is still some confusion worth considering: The first,more than 30 different categories of animals occurred at the same time in the Cambrian,why? The second,no evidence has yet been found to show that the 38-Cambrian organisms are graded animals evolved from the 'Weng an' animals.So,who was common ancestor of more than 30 different categories of Precambrian animals? The third,why evolution rate of different categories of animal since the Precambrian varied so hugely? The fourth,why did Cambrian primitive vertebrate has the original spine of no value?
