热带雨林以其生物多样性著称。原因何在？有一种理论认为，驱动力主要是气候变化。在过去较寒冷、较干燥的时期中，雨林缩小和分隔成片，在其中孤立的群体开始趋异作用，而形成新的物种。澳大利亚昆士兰大学科学家克雷格·莫里兹等现在找到了支持上述观点的基因证据。他们选择 The tropical rain forest is known for its biodiversity. What is the reason? One theory is that the driving force is mainly climate change. In the colder and drier periods of the past, the rainforests shrank and separated into pieces, where isolated groups began to diverge and form new species. Auger University of Queensland scientist Craig Moritz and others now found genetic evidence in support of this view. They choose
