6500万年前，大规模的火山活动在印度-塞舌尔大陆上产生了过去2亿年来最大的大陆熔岩沉积（德干圈闭）。我们使用一种不依赖于分子时钟的方法来推断分子系统发育的年代信息，表明在漂流的印度与世隔绝数百万年后，多种青蛙谱系在德干陷阱火山活动中幸存下来。印度板块和欧亚板块之间的碰撞之后，这些谱系中的几个广泛分散。这种“印度之外”的情况揭示了一种动物地理模式，这种模式可能会调和其他脊椎动物群体的古生物学和分子数据。
Sixty-five million years ago, massive volcanism produced on the India-Seychelles Landmass the largest continental Lava deposit (Deccan Traps) of the past 200 million years. Using a molecular clock-independent approach for inferring dating information from molecular phylogenies, we show that multiple Lineages of frogs survived Deccan Traps volcanism after millions of years of isolation on drifting India. The collision between the Indian and Eurasian plates was followed by wide dispersal of several of these lineages. This "out-of-India" scenario reveals a zoogeographical pattern that might reconcile paleontological and molecular data in other vertebrate groups.
