摘要

．我们提出了一个随机进化模型，通过突变和自然选择在T + d树上进化的群体。我们认为这个模型是描述种群进化适应性景观的一种方式。我们在一组参数上得到了灭绝和生存的明显条件。

Evolution with mass extinction on Td+

. We propose a stochastic model for evolution through mutation and natural se-lection of a population that evolves on a T + d tree. We think of this model as a way of describing the evolution ﬁtness landscape of a population. We obtain sharp and distinct conditions on the set of parameters for extinction and survival.

期刊介绍： The Brazilian Journal of Probability and Statistics aims to publish high quality research papers in applied probability, applied statistics, computational statistics, mathematical statistics, probability theory and stochastic processes. More specifically, the following types of contributions will be considered: (i) Original articles dealing with methodological developments, comparison of competing techniques or their computational aspects. (ii) Original articles developing theoretical results. (iii) Articles that contain novel applications of existing methodologies to practical problems. For these papers the focus is in the importance and originality of the applied problem, as well as, applications of the best available methodologies to solve it. (iv) Survey articles containing a thorough coverage of topics of broad interest to probability and statistics. The journal will occasionally publish book reviews, invited papers and essays on the teaching of statistics.
