Journal ArticleDOI
Gene Regulatory Networks and the Evolution of Animal Body Plans
TL;DR: This work identifies a class of GRN component, the kernels, of the network, which, because of their developmental role and their particular internal structure, are most impervious to change.
Journal ArticleDOI
The Cambrian conundrum: Early divergence and later ecological success in the early history of animals

TL;DR: A compilation of the patterns of fossil and molecular diversification, comparative developmental data, and information on ecological feeding strategies indicate that the major animal clades diverged many tens of millions of years before their first appearance in the fossil record.
Journal ArticleDOI
The Permo–Triassic extinction
TL;DR: The end-Permian mass extinction brought the Palaeozoic great experiment in marine life to a close during an interval of intense climatic, tectonic and geochemical change as mentioned in this paper.

TL;DR: High-precision geochronologic dating constrains probable causes of Earth's largest mass extinction and reveals that the extinction peak occurred just before 252.28 ± 0.08 million years ago, after a decline of 2 per mil (‰) in δ13C over 90,000 years, and coincided with a δ 13C excursion that is estimated to have lasted ≤20,000 Years.
Journal ArticleDOI
Pattern of Marine Mass Extinction Near the Permian-Triassic Boundary in South China
TL;DR: A statistical analysis of the occurrences of 162 genera and 333 species confirms a sudden extinction event at 251.4 million years ago, coincident with a dramatic depletion of delta13C(carbonate) and an increase in microspherules.
