Hypotheses range from explosions in space to “intrinsic genomic reorganization” and many others. Most current ideas fall into three categories. They propose that, “The rapid diversification of animals in the early Cambrian is likely to have been the result of a complex interplay of biotic and abiotic processes.” The rest of the article presents evidence for this statement. A focus was the emergence of Bilaterian animals and the food web that developed with…

S.1992), because of the unexpectedness presence of animal life in the Cambrian. Figures have it that it started back 542 million years ago and terminated approximately 40 million years later. This era is marked by the emerging of profuse skeletonized metazoans, an abrupt intensification in biodiversity and the appearance of most modern lives (Von Bloh 18). Animals that…
