修剪生命之树：k-核渗流作为选择机制
Pruning the Tree of Life: k-core Percolation as Selection Mechanism
摘要：
我们提出了一个进化模型，旨在再现化石数据的统计特征，特别是灭绝事件的分布，每属物种的分布和寿命的分布，所有这些都是已知的幂律类型。该模型结合了种间相互作用和祖先关系。这项工作的主要新颖之处是显示的K-核心渗流作为一种选择机制的可行性。我们给出了可观察到的分布的理论预测，通过计算机模拟确认其有效性，并报告与化石数据良好的一致性。该模型的一个关键特征是由底层物种相互作用的拓扑结构决定的共同进化的适应度景观，生态位自然出现。预测的分布是独立的物种形成的速度，即是否采取渐进或间断的进化观。
英文摘要：
We propose a model for evolution aiming to reproduce statistical features of fossil data, in particular the distributions of extinction events, the distribution of species per genus and the distribution of lifetimes, all of which are known to be of power law type. The model incorporates both species-species interactions and ancestral relationships. The main novelty of this work is to show the feasibility of k-core percolation as a selection mechanism. We give theoretical predictions for the observable distributions, confirm their validity by computer simulation and report good agreement with the fossil data. A key feature of the proposed model is a co-evolving fitness landscape determined by the topology of the underlying species interactions, ecological niches emerge naturally. The predicted distributions are independent of the rate of speciation, i.e. whether one adopts an gradualist or punctuated view of evolution.
