语言多样性演化的理论模型
Theoretical model for the evolution of the linguistic diversity
摘要：
在这里，我们描述了一些重要的比例法则，在地球上的语言分布观察可以从一个简单的计算机模拟出现。语言动力学包括选择性地理殖民、语言异常扩散和变异以及不同地区人口之间的相互作用。结果发现，殖民化后的语言多样性的区域的依赖性显示两个幂律政权，都描述了依赖于突变概率的临界指数。最重要的是，对于世界人口的未来前景，我们的研究结果表明，语言多样性总是减少到一个渐近非常小的值，如果考虑大面积和足够长的时间的人口之间的相互作用。
英文摘要：
Here we describe how some important scaling laws observed in the distribution of languages on Earth can emerge from a simple computer simulation. The proposed language dynamics includes processes of selective geographic colonization, linguistic anomalous diffusion and mutation, and interaction among populations that occupy different regions. It is found that the dependence of the linguistic diversity on the area after colonization displays two power law regimes, both described by critical exponents which are dependent on the mutation probability. Most importantly for the future prospect of world's population, our results show that the linguistic diversity always decrease to an asymptotic very small value if large areas and sufficiently long times of interaction among populations are considered.
